I have recently ordered an Allspace and honestly, this never entered my head once.
I was more interested in boot capacity, access, adaptive cruise control and the auto box. The only time the engine entered my head was during test drive to ensure the 150bhp diesel didn’t feel underpowered for a large car.
I’m not sure if it’s a bad thing or not, but I really do not care as the real world mpg will be in an improvement on my previous car (1.6 petrol Tucson @ 33mpg). I did however notice it comes with adblue that filters out the emissions. Only ever heard of this on lorries before now
