| Volkswagen 3.0-litre V6 TDI 240 PS engine |
Volkswagen's current 3.0-litre V6 TDI common rail diesel engine delivers greater refinement and a boost in power while returning higher fuel economy and emitting less CO2.
The name of the engine derives from its compact shape - six cylinders, three to a side, angled in the shape of a 'V'.
Drawing on the virtues of the outgoing unit, the V6 3.0-litre TDI 240 PS engine, linked to an 8-speed automatic gearbox, has an available torque of 405 lbs ft. The result is a significant gain in performance, with the time taken to accelerate from 0 to 62 mph dropping to 7.4 seconds and a top speed of 136 mph. Despite these gains, combined fuel economy is 38.4 and CO2 output falls to 195 g/km. A V6 3.0 TDI 204 PS engine is also available.
New V6 TDI engines are fitted with Start/stop and brake energy recuperation technology as standard. Start/stop turns off the engine automatically when you're waiting in a traffic queue or at lights, saving fuel and cutting emissions. Brake energy recuperation saves and stores the energy that would normally be lost during braking and uses it for starting and acceleration. Another new feature is the absence of a dipstick, with engine oil levels now shown electronically on the instrument panel.
The TDI badge identifies all our diesel-powered models featuring diesel direct injection and a turbocharger, which supplies the engine with fresh air, thereby providing optimum cylinder charging. After compression, the diesel is injected directly into the cylinders at very high pressure by way of a nozzle.
Driving experience is quiet and refined because effective sound insulation keeps noise to a minimum, while hydraulic engine mounts ensure smooth, low-vibration running. The great advantage of TDI engines is that they are very powerful, even at low revs, and economical across the entire speed range.
