Purpose

I will try my best to provide detailed info on various cars and what is like to live with them, I have already produced a few for Jaguar-car-forums, I will do my best to be unbiased, but it will be hard for some cars. I will re-produce press releases and copy from other motoring news.

BMW to consider a third model to add to it's range 'i' models, but not for a while yet !

BMW is currently weighing which type of model will join its “i” family of low-emission vehicles, a top executive said, adding that the model would arrive after 2020.
“We are still in the strategic research phase where we brainstorm,” BMW Group r&d chief Klaus Froehlich told Automotive News Europe. “Teams that start with a white sheet of paper. They talk with customers, hold workshops, then present their ideas and we decide.”

Froehlich disputed media reports that claimed the third model after the i3 and i8 would be a variant of the X5 premium large SUV. He said the mission of the i subbrand is to change the perception of how a low-emissions car should look and perform, therefore there are no plans to re-package an existing BMW Group model and call it an i model.
Also, he said the i subbrand is supposed to be a starting point for cutting-edge innovation that progressively moves down into the rest of the automaker’s lineup. Current examples include carbon fiber, which is a key part of the i3 and i8 and is moving into other BMWs, and the i8’s plug-in hybrid powertrain, which is being added to high-volume models such as X5, 3 series and 4 series.
Better batteries
BMW will focus on steadily improving the i3 and i8 during the six-plus years until the subbrand’s portfolio grows again.
“We have a minimum 20 percent battery density improvement every three years, thus over the i3 and i8’s life cycle, we will offer more performance, more range or a combination of the two,” Frohlich said.
When asked whether current i3 and i8 owners would be able to switch to the more powerful electrical powertrains Froehlich said: “I don’t think a retrofit makes sense. When better batteries are available, we could then offer models with a longer range or with the same range but at a lower price.”
He added that replacing the batteries is very complex because they are integrated and bonded into the chassis.
Last year, BMW sold 16,052 i3s and 1,741 i8s.

The new Lotus Exige S Automatic gives the pure, extreme, high performance Lotus driving experience

The new Lotus Exige S Automatic gives the pure, extreme, high performance Lotus driving experience with both automatic and paddle shift manual options.
  • 0-60mph in 3.8 seconds (0-100kph in 3.9 seconds) - 0.1 seconds quicker than the manual Exige S
  • As fast around the Lotus Hethel test track as the manual Exige S
  • 240 milliseconds gearshift speed
  • Weighs just 1182 kg (unladen)
  • Significant CO2 reduction from 235g/km (Exige S manual) to 222g/km ( Exige S Automatic)
  • Available in both coupĂ© and roadster versions
The much-loved Lotus Exige, with its ground-breaking, extruding aluminium and bonded chassis, lightweight composite body and race-bred double wishbone suspension now features an automatic transmission option that continues its uncompromised sporting profile.
With an exceptional power-to-weight ratio of 292 hp/tonne and stunning performance, an even more focused driving experience is made possible by including the 6-speed automatic gearbox option. 

The automatic control panel is integrated neatly into the centre console of the cockpit, with buttons for Park, Reverse, Neutral and Drive with beautifully crafted, forged aluminium, manual-shift paddles located behind the steering wheel cross-spokes, upshifts take just 240 milliseconds, with rapid downshifts accompanied by a throttle-blip (when in Sport mode).


In both automatic and manual gearshift modes, the Exige S provides the driver with a very rapid driving experience. In Sport mode, throttle response is sharpened and the Lotus Dynamic Performance Management (DPM) increases the traction slip thresholds allowing the driver even more vehicle control before an intervention is required. The system also opens the engine exhaust bypass valve at mid-to-high engine speeds. The Optional Race Pack includes Race mode, which reduces the intervention of the DPM further and incorporates a Launch Control system.

Jean-Marc Gales, CEO Group Lotus plc, stated: “Expanding the Exige range, with a new automatic gearbox, opens up a new market for those who prefer using a paddle shift with the alternative of an automatic gearshift. We expect that the Exige S Automatic will account for over a third of the total global sales for the Exige S range as many drivers will appreciate the involvement of a manual paddle-shift and the convenience of an automatic.”

Aided by the 345bhp, 3.5-litre, supercharged V6 engine, the Lotus Exige S Automatic reaches 60 mph in 3.8 seconds and 100 km/h in only 3.9 seconds. 100 mph (160 km/h) comes up in just over 9 seconds before reaching a top speed of 162 mph (261 km/h); 145 mph (233 km/h) for the Exige S Roadster. Its CO2emissions rating of 222g/km is low enough to warrant a tax reduction in some markets compared to the Exige S with the manual.

The automatic transmission is available on both Exige S and Exige S Roadster models. The RRP, excluding tax, is £1,667 (UK) and €2,185. Orders can be placed immediately.
