Opel will present the new Astra 1.6 CDTI at the upcoming Geneva Motor Show in March. To be available in the high-volume Astra hatchback, Astra notchback and Astra Sports Tourer models, the 1.6 CDTI diesel engine made its debut last year in the Zafira Tourer. (Earlier post.)
The new diesel delivers 100 kW/136 hp and 320 N·m (236 lb-ft) maximum torque (as in the Zafira), with fuel consumption of 3.9 liters diesel per 100 km (60 mpg US) in the NEDC test procedure (New European Driving Cycle)—up to up to 8% less than the 1.7-liter engine it is replacing. An 81 kW/110 hp version of the new turbo diesel is even cleaner and more economical: 3.7 l/100 km (63.6 mpg US) with CO2 emissions of 97 g/km. The 81 kW unit delivers 300 N·m (221 lb-ft) maximum torque (7% more than the 1.7-liter predecessor with the same hp).
Various performance levels of the newest generation all-aluminum turbo diesel will successively replace the engines with 1.7-liter displacement in Opel’s diesel portfolio.

The diesel is the first unit in the Astra portfolio to comply with the future Euro 6 emissions standard, making it the cleanest diesel Opel has ever built. The engine is best-in-class in noise and vibration generation due to its optimized component design; an especially efficient combustion process with multiple injection; and additional acoustic measures.
Opel says that the new 1.6 CDTI is the quietest diesel in its class, and calls it the “whisper diesel”. Further contributors to its performance are the high-pressure common rail system and lean nox trap exhaust after-treatment (LNT). Together with the VTG turbocharger (variable turbine geometry) that enables powerful response, they are the engine’s core technical elements.
The 320 N·m of maximum torque is 7% more than the torque delivered by its 130 hp 1.7-liter predecessor. At the same time, fuel efficiency is improved and CO2 emissions are reduced.
The turbo unit accelerates the Astra from zero to 100 km/h in 10.3 seconds (notchback: 10.1 seconds); from 80 to 120 km/h in fifth gear it needs 9.2 seconds (notchback: 9.1 seconds, Sports Tourer: 9.9 seconds). Top speed is 200 km/h (124 mph) and the notchback even reaches 205 km/h (127 mph).
With the 81 kW variant, the Astra hatchback, notchback and Sports Tourer accelerate from zero to 100 km/h in 12.0 seconds, and top speed is 186 km/h (116 mph).
The new 1.6 CDTI engine in the Astra comes coupled with the further developed, improved six-speed manual transmission.
The 100 kW/136 hp Astra hatchback 1.6 CDTI with Start/Stop and six-speed manual transmission is available from €22,200 (US$30,000), the notchback from €22,700 (US$30,700) and prices for the Sports Tourer counterpart start at €23,300 (US$31,510) (RRP incl. VAT in Germany).
