Diesel Engines


Economical, efficient, powerful – by design

Whether you’re a company car driver, running a fleet of vehicles or a private buyer, we know you need the most economical and efficient cars to help you improve fuel consumption, as well as keep CO2 emissions, Company Car Tax and Whole Life Costs as low as possible.

Our range of ecoTEC ‘Whisper Diesel’ and Turbo petrol engines is designed to offer you our highest mpg and lowest emission cars, with the longest range, and all while continuing to fuel driving enjoyment and powerful engine performance.

The combination of our ecoTEC technology and family of state-of-the-art, four-cylinder diesel engines delivers ultra-efficiency, and smooth power with high levels of reward. Unmistakably quiet and refined, ecoTEC diesel engines – boast vastly reduced levels of noise, vibration and harshness.


Key ecoTEC diesel engine features include

  • An aluminium cylinder block and bedplate have been used to save weight and help improve engine efficiency.
  • Performance has been optimised with closed-loop combustion control and multiple fuel injections, up to 10 per cycle, for efficient, clean and quiet running.
  • Acoustic covers are used across the unit, all of which help to attain superb levels of refinement.
  • The 1.6CDTi has the lowest internal engine friction rating in its class. A switchable water pump and variable displacement oil pump all contribute to the outstanding fuel economy and reduced CO2 emissions.

Vauxhall ecoTEC start/stop system

Vauxhall’s cutting edge Start/Stop fuel saving and emissions reduction technology is available on all of our ecoTEC diesel engines. The system switches the engine off when the vehicle stops at the lights or in traffic and then restarts it automatically once the clutch is depressed.


Efficiency is also aided by the addition of our brake energy regeneration system. This re-uses energy recovered from vehicle braking, helping to improve overall fuel consumption.
