USA - The Mercedes CLA gets a more refined look as well as a host of other trim and equipment upgrades.

The sporty, expressive design of the CLA is now further honed in a facelift involving new front and rear bumpers as well as new light-alloy wheel designs. The interior also benefits from numerous enhancements, among them new seat covers and trim parts, as well as chrome-plated controls. LED High Performance headlamps, HANDS-FREE ACCESS and further possibilities for integrating smartphones into the control system are all options that serve to enhance safety and comfort. 
The addition of Active Brake Assist as a standard feature further strengthens the CLA's credentials as a leader in its class, as does HANDS-FREE ACCESS as an optional convenience feature. The Mercedes-AMG CLA45 now features even more dynamic styling and a further upgraded interior. With a peak performance of 375 hp and maximum torque of 350 lb-ft, it is amongst the most powerful vehicles in its segment.

The facelifted version of the CLA 4-door Coupe will make its physical debut at the New York International Auto Show on March 23rd. The 2017 CLA will be available in US- dealerships in the third quarter of 2016.
In undertaking the facelift modifications, the Mercedes-Benz designers have subtly honed the distinctive look of the CLA. All models now have a new front bumper with a silver, black or chrome trim strip. 
The rear bumper is optionally available with a panel incorporating a trim strip in chrome or black (Night Package) between the tailpipes. The tailpipe trim panels themselves are now integrated flush into the bumper. This adds visual width to the vehicle and ensures a superior high-quality appearance thanks to even and narrow gaps where the panels join.
There is a new metallic paint available, Lunar Blue. Most of the available wheels now feature a new design – overall, six different wheels are available to chose from for the CLA250. The CLA previously included the latest generation of assistance and safetysystems that are, in some cases, only now gradually being introduced in the other model series. 
Among these are Active Brake Assist as standard (known until now as COLLISION PREVENTION ASSIST PLUS), which is able to trigger autonomous braking as a means of reducing the danger of rear-end collisions, as well as the transmission mode selection function DYNAMIC SELECT. 
With this system the vehicle characteristics can be adjusted at the touch of a button, as the system modifies the engine, transmission and steering feel. The ambient lighting system, which can be individualized by setting any one of twelve color moods, has been part of the specification since the start.
The interior: slimmer display, new trim parts, chrome-plated controls
The interior also benefits from features such as new seat covers and trim parts, as well as chrome-plated controls. The highlight here is a much slimmer-looking freestanding 8-inch media display with a new-style glass cover, standard equipment in the US. The new-style dials and red needles in the instrument cluster make it easier to read the instruments.
Meticulous attention to detail is also evident from the silver chrome finish to the controls and to the fascia and switches in the doors for the electrically adjustable seats, as well as from the chrome surround to the stowage compartment in the center console.
New trim elements in sail-look finish, matt black ash wood, black DINAMICA microfiber trim (optional in conjunction with the Sport Package Plus) or aluminum with honeycomb grain, serve to liven up the interior. There is also a revised range of seat covers: for the optionally available Interior Package there is a new leather upholstery option in beige/black.
The equipment features: LED High Performance headlamps as an option 
The CLA is optionally available with LED High Performance headlamps with a color temperature that is closer to that of daylight than traditional xenon headlamps. This is more restful to the eyes and therefore provides relief to the driver at night. The 34-watt LED low-beam headlamps also have very low energy consumption – around 60 percent less than xenon and around 70 percent less than halogen.
The low-beam headlamps use LED projection technology, while the main-beam headlamps use LED reflection technology. Direction indicators, daytime running lamps and position lights are in the form of multifunctional fiber-optic cables, which are also used for the 'Coming Home' function. As all lights use LED technology, there is never a need to change a bulb over the entire service life of the vehicle.
The new optional LED High Performance headlamps are combined with automatic intensity control tail lights, which reduce the dazzling effect for vehicles following. The multi-level functionality regulates the brightness of the brake lights and direction indicators in three stages (Day/Night-time driving/Night-time stationary).
Loading becomes easier with the HANDS-FREE ACCESS option. This system allows the trunk lid or tailgate to be opened without any physical contact; all it takes is a motion of the foot in the area of the rear bumper. HANDS-FREE ACCESS is now included as part of the Premium Package.
The optionally-available Smartphone Integration Package allows the integration and voice-operated control of iPhones® and Android smartphones via Apple CarPlay® and Android Auto™ respectively. Selected functions can be operated using vehicle controls, thus allowing safe use even while on the move.
A Rear View Camera is now included in the standard equipment for the United States.
Drive system: Efficient and dynamic
The four-cylinder engine in the CLA250 delivers an output of 208 hp and is paired as standard with the 7G-DCT. It is available in both front-wheel drive or with optional 4MATIC.

Latest AMG design language and improved aerodynamics: AMG CLA45 
"Avant-garde meets Driving Performance" is the motto for the Mercedes-AMG CLA45. Offering a unique combination of a sporty driving experience, extravagant design and maximum individuality, the CLA45 also benefits from updated exterior asthetics. LED High Performance headlamps now come as standard, as does the twin louver radiator grille finished in silver chrome.
Aerodynamics have been further improved and the coefficient of drag has been reduced, all to the benefit of driving dynamics and stability. Further exterior features of the facelift include the AMG front bumper in a new A-wing design with front splitter inserts in matte titanium grey and high-gloss black flics, and a new design for the AMG lip spoiler on the trunk lid. New at the rear is the design of the diffuser insert, with four vertical fins. An AMG Aerodynamics package is now available as an optional extra. This comprises a larger front splitter, additional flics, a black AMG lip spoiler plus black accents over the simulated air outlets on the rear bumper.
Two attractive light-alloy wheels join the range: the standard specification includes 18 x 8.0-inch AMG ten-spoke wheels painted titanium grey or black and with a high-sheen finish, with 235/40 R 18 tires. Available as an option are 19 x 8-inch AMG cross-spoke light-alloy wheels with 235/35 R 19 tires. Here, too, there are two color variants, with matte black or titanium grey paintwork, in each case with a high-sheen rim flange.
The interior has been similarly upgraded and interiors are given an exclusive finishing touch of red contrasting topstitching. The new AMG trim design features a matte painted finish while the structure still has a polished surface that bears the AMG logo. It is available in black/red or in black/silver, depending on the chosen upholstery. Also new is the optional AMG DINAMICA Interior package with a trim element in DINAMICA as well as a full-DINAMICA AMG Performance steering wheel.
With a peak performance of 375 hp and maximum torque of 350 lb-ft, the Mercedes- AMG CLA45 4-door Coupe is among the most powerful vehicles in its segment, accelerating from 0 to 60 mph in just 4.1 seconds.
Extensive modifications undertaken by Mercedes-AMG last September had already added to the fun at the wheel and emotional appeal of the CLA. Along with the more powerful engine, the new features included the AMG DYNAMIC SELECT transmission modes as standard, plus shorter gear ratios of the AMG SPEEDSHIFT DCT 7-speed sport transmission. A mechanical limited-slip front differential is available in conjunction with the Dynamic Plus package (optional extra).
Did you know that... 
...on sale in the USA since 2013, the CLA was the first compact car to be marketed in the US market by Mercedes-Benz. As the new entry-level model, it has proved hugely successful, with sales of 29,643 units (2015: +8.3% vs. 2014) making the USA the single most important market for the CLA in 2015.
…more than four million compact cars from Mercedes-Benz have already been delivered to customers worldwide?
…the model series is built at the company's production facility at Kecskémet in Hungary? Production of the compact four-door Coupe started in January 2013. Since the facility opened in 2012 a total of 500,000 vehicles have already left the production line of the Kecskémet plant, which also produces the B-Class.
...as far as its technology is concerned, the AMG 2.0-liter turbo unit is related to the 4.0-liter V8 biturbo engine in the Mercedes-AMG GT that delivers up to 503 hp.
...the four-cylinder turbo engine has already received the renowned "Engine of the Year Award" twice? The AMG unit won the award in the category for engines with a displacement of 1.8 - 2.0 liters in both 2014 and 2015. The independent experts were impressed by the trailblazing engineering and outstanding characteristics of this high- end four-cylinder unit.

Mercedes-Benz announces details of the All New GLC Sports utility vehicle.

The second generation of the mid-range SUV from Mercedes-Benz goes by the name of GLC and represents a big step forward on several fronts: On a technical level the new SUV clearly makes its mark with the excellent standard of safety that is a brand hallmark. 

Featuring state-of-the-art assistance systems and outstanding energy efficiency. Fuel consumption has been cut by up to 19 per cent in comparison to the previous model. 


At the same time, the AIR BODY CONTROL multi-chamber air suspension that is without parallel in this segment, the extended range of DYNAMIC SELECT dynamic transmission modes and the 4MATIC permanent all-wheel drive increase not only the ride comfort, but also the vehicle's sporty agility – whatever surface it is driving on. 

Visually, the body follows the clear and sensual design idiom which was demonstrated so successfully by the GLC Coupé showcar concept in the spring, and which serves as the standard for future SUV families.

"Our new GLC represents a further, systematic step in the implementation of our successful SUV philosophy. 

It combines the ultimate in driving comfort with a sporty touch, impresses on the road and – more than ever – off it as well, and appeals to the eye with the new design and equipment line," says Thomas Weber, member of the Management Board of Daimler AG and responsible for Group Research and Mercedes-Benz Cars Development.

The design philosophy behind the new GLC essentially favours sensual purity and a modern aesthetic over the classic off-road look. 

The dynamic design exudes emotional appeal while also employing purist forms. Surfaces embodying a degree of tension and precise lines cite the clear design line followed by all state-of-the-art SUVs from Mercedes-Benz. 

The GLC only represents a departure from its progenitor – the G-Class – in terms of appearance, however. On a technical level it sets new benchmarks in all disciplines – the mid-size SUV's off-road capabilities remain as outstanding as ever.

The characteristic SUV front with a short, succinct overhang, upright, three-dimensional radiator grille with a twin louvre and centrally positioned brand star follows the successful new design line. Striking headlamps, optionally available as LED High Performance lamps, lend the GLC a self-confident look which is further emphasised by their distinctive night design. 

The bumpers with integrated underguard come in three variants: in addition to the base version there is a version optimised for off-road use with a larger angle of approach/departure, plus a particularly sporty AMG variant.

The side view showcases the almost coupé-like greenhouse, which together with the 118 millimetres larger wheelbase lends the GLC an elegant long profile. This impression is further reinforced by the gently sloping dropping line which is a hallmark of the brand and by the powerful shoulders. 

The rising lower feature line also enlivens the vehicle's side view. Matt black cladding in the wings, wheels up to a size of 50.8 cm (20 inches) and the optional side running board provide clear indications of the GLC's off-road credentials.

The rear is characterised by the broad, muscular shoulders, the horizontal orientation of the contour lines and the split LED rear lamps featuring a distinctive night design. 

As on the front, the different bumper variants are available here as well. By integrating all the antennae into the exterior mirrors and the roof spoiler, it has been possible to do away with the fin which has featured on the roof to date.

GLC interior: added class

The paradigm shift in the area of design affects not only the outside appearance. The model change also signals a marked upgrade for the interior. 

A modern setting prevails which is quite in keeping with the standard set by its bigger brother, the GLE. The new design idiom combines sensual purity with dynamic sportiness and embodies a new interpretation of modern luxury.

The GLC's interior conjures up the feel-good atmosphere which is a brand hallmark courtesy of high-class materials featuring a hand-crafted character, such as nappa leather or open-pore wood trim, meticulously finished details and an appealing overall touch and feel. 

Last but not least, substantially more space is available for occupants and luggage. The optional large-area panoramic glass roof further enhances the light and airy feel inside.

A key focus of the totally new interior design is the dashboard and the centre console with its flowing lines, with a large, one-piece console panel performing an elegant sweep from the centre air vents to the armrest. These clear-cut lines create a feeling of open space and establish a purist, modern vibe. 

The newly developed innovative touchpad in the handrest over the rotary pushbutton nestles ergonomically in the centre console. As on a smartphone, this provides for very simple and intuitive operation of all the head-unit functions using finger gestures. 

The touchpad also permits letters, numbers and special characters to be entered in handwriting – in any language supported by Audio 20 or COMAND Online. A centrally positioned media display is partially integrated above the centre console. 

Five round air outlets with metallic "cool touch" effect lend the dashboard a sporty air and create an interesting contrast to the warm look of the other materials.

More space, more fun, more comfort

In comparison to its predecessor, the new model is substantially more spacious for front and rear occupants alike. The increase in the GLC's length in comparison to the previous model has been translated effectively into useful interior space. 

Almost all key comfort factors have been improved – substantially in some instances – above all the space on the rear bench. Comparison of key comfort dimensions:

GLKGLC
Middle of front wheel to driver SRP15271567+40
SRP distance, driver to rear808846+38
Effective legroom in rear891948+57
Elbow room in front14421449+57
Elbow room in rear mm14401474+34
Shoulder room in front14011455+54
Shoulder room in rear14081436+28

Another comfort criterion – entry and exit space for the rear passengers – has also been enhanced substantially, with 34 millimetres more foot space now available for the purposes of entering and exiting the vehicle.

Through the effective use of space and intelligent packaging, the engineers have also managed to increase the size of the luggage compartment with level a load area and its attendant utility value substantially. The rear bench features a 40/20/40 split and offers a cargo position which increases the load capacity by locking the backrests at a steeper angle. 

The load capacity behind the rear bench increases by 80 to 110 litres, to a total of up to 580 litres. In all, the GLC 1600 is able to transport up to 1600 litres – 50 litres more than was previously possible.

The maximum luggage compartment length is 1320 millimetres, while the maximum width increases by 150 to 1100 millimetres.

Added convenience for loading and unloading is provided by lowering of the load compartment sill by 40 mm with the AIR BODY CONTROL option and by HANDS-FREE ACCESS, which enables the tailgate to be opened automatically by performing a swiping movement with the foot under the bumper.

Energy efficiency: crucial parameters

Mercedes-Benz has applied an extensive package of measures to enhance the GLC's energy efficiency and performance substantially. 

Modified or new drive systems, outstanding aerodynamics and intelligent lightweight design are the primary factors behind the vehicle's fuel efficiency. 

The diesel and petrol models boast significant reductions of up to 19 per cent in both fuel consumption and CO2 emissions in comparison to the previous generation, while at the same time improving performance with the same power output:

All models comply with the EU6 emissions standard and offer a start/stop function. 

For the first time in this segment, with the GLC 350 e 4MATIC Mercedes-Benz is additionally offering a plug-in hybrid which combines the merits of agile all-wheel drive with the lowest fuel consumption and emissions: the mid-size SUV emits only 60 g of CO2 per km* and attains a top speed of 146 mph with a best-in-class system output of 211 + 116 hp.

The semi-electric vehicle can cover up to 21* miles in zero-emission all-electric mode, accelerating to 62 mph in 5.9 seconds if necessary, courtesy of the boost function. 

Like its plug-in big brother of the S-Class, the GLC 350 e 4MATIC offers all the characteristic comfort and efficiency systems - from the flexible, intelligent operating strategy through the specific hybrid driving programs and the haptic accelerator pedal to pre-entry climate control. 
  
* Provisional figures

The design transition has also bestowed superlative aerodynamics on the new GLC. With a Cd value of 0.31 (GLK 0.34) and total aerodynamic drag of 0.794 (GLK 0.87), it sets a clear benchmark in this segment. 

Apart from the vehicle's substantially more aerodynamically efficient basic shape, this exceptional aerodynamic performance also results from a host of solutions relating to points of detail, such as sealing of the radiator and headlamp surrounds, a radiator shutter, the extended roof spoiler or the optimised underbody panelling.

Despite markedly larger outer dimensions, a longer wheelbase and a more extensive scope of equipment, the vehicle's weight has been cut by 80 kilograms. 

The main contributory factor to this reduction is the totally new body, which is 50 kilograms lighter than the smaller GLK counterpart, thanks to an intelligent mix of materials comprising aluminium and high- to ultra-high-strength steels. 

Aluminium components additionally reduce the weight of the chassis, which also benefits ride comfort due to the attendant reduction in unsprung masses. 

The optional AIR BODY CONTROL full-support multi-chamber air suspension features spring elements in lightweight yet robust glass-fibre-reinforced plastic, which reduce the system weight in comparison to conventional air suspensions. 

The use of the new compact transfer case as an add-on module and the 9G-TRONIC with its magnesium transmission housing results in a reduction in weight of 12 kg in comparison to the previous model.

AIR BODY CONTROL: innovative air travel

The new GLC features the AGILITY CONTROL suspension with steel springs and a variable damping system as standard. The GLC is the sole model in this market segment to offer the option of fitting the chassis with a full-support multi-chamber air suspension system and electronically controlled, continuously adjustable damping.

The AIR BODY CONTROL suspension combines excellent driving stability and sporty agility with optimum comfort and outstanding off-road capabilities. Specific characteristics are pre-selected according to the settings of the DYNAMIC SELECT driving dynamics program. 

In Sport mode the GLC's occupants feel as if they are sitting in a sports car with a high level of lateral dynamics due to the tauter connection of the chassis, which is additionally lowered by 15 millimetres. 

Comfort mode offers the very opposite ride experience, focussing on particularly comfortable running with soft connection of the chassis. 

To ensure maximum driving safety in this mode, too, the spring and damper forces adapt within 60 milliseconds in response to sudden evasive manoeuvres, for example. 

When the GLC is equipped with the Off-Road Engineering package, AIR BODY CONTROL optimises the wheels' ground contact, ensuring good progress in off-road terrain by raising the driving level by up to 50 mm and providing for particularly soft basic tuning.

Further benefits of the system include reduced rolling during cornering, automatic level control and lowering of the load compartment sill for convenient loading and unloading.

Powertrain: agility, dynamism and comfort à la carte

The new GLC offers the DYNAMIC SELECT handling control system with five driving programs as standard. In addition to the ECO, COMFORT, SPORT, SPORT+ and INDIVIDUAL settings which are familiar from other models, the new all-rounder can also be equipped with the Off-Road Engineering package. 

This comprises up to five programs. "Slippery" and four off-road driving programs are totally new here. "Off-road" is predestined for easy off-road terrain such as gravel or sand tracks. "Incline" boosts climbing capabilities on steep ramps or long, slow uphill stretches. 

In conjunction with AIR BODY CONTROL air suspension, the additional "Rocking Assist" program offers the last resort, should the vehicle get stuck. Here the driving level is raised by 50 millimetres and the wheel-slip control thresholds are increased so as to enable the GLC to work its way free. 

The fourth off-road program, "Trailer", is designed for optimum trailer towing off-road and facilitates moving off on wet grassland, for example. The Off-Road Engineering package further includes a robust Gemtex underride guard, which takes the stress out of heavy ground contact as on the previous model, and Downhill Speed Regulation. 

The system, which goes by the abbreviated name of DSR, automatically maintains the speed which has been pre-set on the cruise control on steep downhill stretches.

All DYNAMIC SELECT programs are visualised on the central media display. Especially impressive are the off-road animations: various parameters, such as incline, steering angle or heading are presented in dynamic mode in real time on the central media display.

All models feature 4MATIC permanent all-wheel drive with a basic drive torque split of 45 to 55 percent between front and rear axle. In cooperation with the ESP®, ASR and 4ETS dynamic handling control systems, this provides for superior and clearly predictable handling. 

The multiple-disc clutch in the centre differential assists the system in the event of really low friction coefficients between tyre and road, for example on snow or ice. A basic locking force of 50 Nm between the front and rear axles brings about a significant increase in traction with the same high level of driving stability.

The nine-stage 9G-TRONIC automatic transmission also comes as standard on the GLC 220 d 4MATIC, GLC 250 d 4MATIC and GLC 250 4MATIC. 

Depending on the mode selected for the DYNAMIC SELECT dynamic handling control, the automatic transmission with a torque converter boasts great agility and responsiveness or poised composure. 

The potential of the transmission is exploited to the full. It offers an impressively high shift speed and perfect transitions for energetic sprinting as well as with gentle, barely perceptible gear changes for enjoyable cruising.  

As with all hybrid models from Mercedes-Benz, the GLC 350 e 4MATIC is equipped with the latest version of 7G-TRONIC PLUS, which has been specifically optimised in line with the needs of hybrid applications and also combines high driving dynamics with excellent drive comfort and superior efficiency.

Mercedes-Benz Intelligent Drive: guardian angels on board

Almost all of the driver assistance systems which are familiar from the C-, E- and S‑Class are available for the new GLC. As part of the Intelligent Drive concept, these systems combine data from various sensor technologies to enhance comfort and safety substantially. 

COLLISION PREVENTION ASSIST PLUS, Crosswind Assist, Headlamp Assist and ATTENTION ASSIST are on board as standard. 

The Driving Assistance package Plus provides an even more comprehensive scope of active safety features, comprising DISTRONIC PLUS with Steering Assist and Stop&Go Pilot, PRE-SAFE® Brake with pedestrian detection, BAS PLUS with Cross-Traffic Assist, Active Blind Spot Assist, Active Lane Keeping Assist and PRE-SAFE® PLUS. 

The latter feature also offers added protection in the event of a rear-end collision. By means of a radar sensor in the rear bumper PRE-SAFE® PLUS identifies impending rear-end collisions, alerts the traffic behind by operating the hazard warning lights at a particularly eye-catching flashing frequency, activates preventive occupant protection measures and brakes the vehicle to a standstill after a rear-end collision to reduce the levels of stress acting on the occupants. 

Greater safety for all road users is provided by Traffic Sign Assist with its wrong-way warning function, which in addition to speed limits can also alert the driver to no-overtaking and no-entry signs.

On vehicles equipped with the LED Intelligent Light System, Adaptive Highbeam Assist Plus allows main beam to be left on permanently by masking out the area of the main-beam light cone which is occupied by other vehicles. 

Simpler handling and a clearer view when manoeuvring in tight spaces or driving in dense urban traffic are ensured by the 360° camera, which is able to show the vehicle and its surroundings from different perspectives, and by Active Parking Assist, which manoeuvres the vehicle fully automatically into detected parallel and end-on parking spaces.

The improved ergonomics and simpler controls in the GLC also help to enhance safety. All important vehicle functions and settings can be carried out intuitively using the central rotary pushbutton or the touchpad. The desired settings or information are visualised by the large, partially integrated colour media display in the middle of the dashboard.

Direct selection buttons next to the light switch module to the left of the steering wheel additionally enable direct activation of the most important assistance systems.

Also new is the Head-up Display, (HUD). The HUD displays important information directly in the driver's field of vision on the front windscreen, thus providing for clear legibility and less distraction from the road ahead. 

The system provides information on speed, posted speed limits, navigation instructions and messages from the DISTRONIC system.

Airbag & co.: cushioning protection for the occupants

In keeping with the Mercedes-Benz tradition, the body forms the foundation for exemplary crash safety. 

A high-strength safety passenger compartment forms the core of this concept. It is surrounded by specifically designed and field-tested deformation zones, which ensure maximum safety for the occupants by virtue of optimised force paths and a combination of die-cast aluminium components and ultra-high-strength materials.

In addition to 3-point safety belts with pyrotechnical and reversible belt tensioning and belt-force limitation for driver, front passenger and those in the outer rear seats, numerous airbags serve to protect the vehicle's occupants in an accident. 

These include the combined thorax/pelvis sidebags for driver and front passenger and a newly developed windowbag extending over both seat rows, the optional sidebags for the outer rear seats and a driver kneebag.

The front passenger seat can additionally be fitted with automatic child seat recognition, which dispenses with the previous transponder in favour of a weight mat. This enables any child seat to be used. The airbag is automatically deactivated when a child seat is fitted and reactivated once it has been removed.
