• Latest model to benefit from economical and refined 1.6 CDTi ‘Whisper Diesel’
• From 104g/km CO₂ and up to 72.4mpg combined economy
• Up to 320Nm torque and 136PS offers increased performance

Vauxhall’s rakish GTC, is now available with the refined and powerful 1.6 CDTi ‘Whisper Diesel’ engine. It is the latest model to benefit from the economical new engine, following its introduction in the Astra, Meriva and Zafira Tourer.

The engine replaces the 1.7 CDTi, providing 320Nm torque (up 20Nm) and 136PS (an increase of 6PS) to ensure its refinement and economy is matched by its performance, delivered through an improved six-speed manual transmission.

Available in Sport, Limited Edition and SRi trims and equipped with Start/Stop plus a braking energy recuperation system as standard, the GTC 1.6 CDTi delivers fuel economy of up to 72.4mpg on the combined cycle and has CO₂ emissions from just 104g/km.

The already Euro 6-compliant 1.6 CDTi is one of the best engines in its class for noise and vibration thanks to an efficient combustion process with multiple injection, re-designed components and the use of acoustic covers.

“We are delighted to see the 1.6-litre ‘Whisper Diesel’ introduced into our flagship GTC model,” said Stuart Harris, Vauxhall’s Head of Carline Brand. “The new 1.6-litre engine is a result of significant investment and provides an exceptional blend of performance, refinement and economy.”

The GTC can be ordered with the new engine for prices starting at £22,260.
