PSA’s Puretech petrol engines typically offer good mechanical refinement, and the same is true of the one in the DS 7 Crossback. Full throttle acceleration is met with a mild hum that only becomes truly noisy as you reach the top end of the rev band.
Not that you’ll be inclined to allow the tacho needle to stray that far north too often anyway, since the engine starts to run out of puff from above 5000rpm. We measured the 1.6-litre motor’s vocality, at max revs in third gear, at 78dB, and at 68dB at a steady 70mph cruise.
By comparison, the Toyota C-HR hybrid we tested in 2016 measured respective figures of 73dB and 67dB – the latter, allowing for the effect of the Toyota hybrid transmission, being quite flattering on the DS 7.
There isn’t a great deal separating the acceleration figures we recorded on the car from those claimed by DS. According to the French manufacturer, its new SUV will hit 62mph from a standstill in 8.3sec; on a dry track with two occupants on board, we measured the 0-60mph sprint at 8.6sec. While the Crossback’s Puretech engine pulled strongly once up and running, the 235/50 front tyres did momentarily struggle to find purchase off the line.
