Opel has updated the Astra GTC with the company’s new 1.6-litre CDTI engine that is already on offer on the rest of the Astra line-up.

Astra GTC engine specs

The new 1.6-litre CDTI engine replaces the previous 1.7-litre unit, and delivers 100 kW and 320 Nm of torque – an increase of 5 kW and 20 Nm. With the all-new aluminium turbo diesel, the Opel Astra GTC manages to return an average 4.1l/100 km and emits 109 g/km of CO2.

The model can accelerate from 0-100 km/h in 10.2 seconds before hitting a top speed of 198 kph.

In addition being faster than its predecessor, the new 1.6 CDTI engine comes with Start/Stop, plus a braking energy recuperation system as standard and is coupled with an improved six-speed manual transmission. The engine is also the first in the Astra family to already comply with the future Euro 6 emissions standard, making it the cleanest diesel Opel has ever built.

Marketed as a “whisper-diesel” thanks to its low operating noises and running smoothness, the Astra GTC 1.6 CDTI is currently available to order. South African availability is yet to be confirmed.
