What is it?
Vauxhall's all-important Nissan Qashqai rival mated to a new, PSA-sourced diesel engine. Brought in primarily to ensure all PSA Group cars meet the most stringent emissions regulations, the new 1.5-litre unit officially replaced the 1.6-litre diesel back in May, but this is our first chance behind the wheel of it. We have, however, tried it in a few other PSA Group models, including the recently facelifted Peugeot 308.
The new diesel engine, codenamed DV5R, is a bit ahead of the curve because it's already compliant with the tightest EU6c emission legislation, which won't be enforced until 2020. That legislation is specifically targeted at reducing NOx and particulate emissions in the real-world and not on an unrealistic laboratory test cycle.
Its timing is crucial, with the hope of such engines putting pay to the rather unhealthy image diesel has been labelled with of late in many European countries. The 1.5 Turbo D makes use of the full suite of exhaust-cleaning tech, including the now-common AdBlue urea injection system and a particulate 'trap' filter.
However, the new tech has some other effects: the 1.5-litre diesel produces 4g/km more CO2 officially than the old 1.6 and fuel economy is down by just under 2mpg. PSA is taking the lead in publishing more realistic figures, though, so that may be why. Power has risen by 10bhp, which alongside new internals and a different engine tune helps to reduce the 0-62 mph time by just under a second. The top speed is unchanged.
