Why waste energy and tyres accelerating fast?
We do it cycling too ? It's just in-case !

In some cases, even with outwardly the same engine, same capacity, two different generations of the same car can behave completely different.Like others have said, trickery and turbos etc increase power. With turbos you need to make sure oil is changed regular. You can get say anything from 120 bhp to 200 bhp out of a 1.6 petrol !!
Things have moved on massively. Diesel turbos pull like stink from low revs, but some of the newer petrol turbo engines produce a huge amount of power.
I would recommend driving some though. As peak power doesn't come in when you need it. We have two cars, an old 1.8 with VVT and a new 1.6 VVT, both from the same company and the same power. The old 1.8 pulls better and accelerates much quicker in gear, despite the same BHP. The torque is better on the old car. The new car is more fuel efficient !
Unfortunately the Citroen auto is an horrendous thing, please please please make sure he has a good drive in one before he buys, it is one of the worst auto systems I have ever had the misfortune to have to drive. They took a great idea from the German's & tried to make it as cheap as possible in their on unique French way. Whereas the Germans use a double clutch to make almost seamless changes, the French use an hydraulic or might even be pneumatic clutch which is supposed mimic a driver, it really is horrible & this is from somebody who had Citroens for over 20 years.Having said that the better fuel economy appeals to him as much as anything, plus he's hoping to get an automatic as he's always preferred that since he had a Bongo a few years ago.
Thanks, I'll make sure he has a decent test drive before we decide.Unfortunately the Citroen auto is an horrendous thing, please please please make sure he has a good drive in one before he buys, it is one of the worst auto systems I have ever had the misfortune to have to drive.

Be aware with the advances in turbocharging similar sized engines can have wildly different outputs...so, you can get a 140bhp 1 litre in a Ford Fiesta but slightly larger engines in the same car with half that power. Totally confusing or what.?You can have two similar engines with different power outputs (forget about bhp, just think delivered power) if one has been fiddled/tuned/set up to use more fuel or, if one has had some fancy work done to it such as balancing, porting, exhaust work etc etc.
Two identical engines will have extremely similar power delivery, so if the one delivers more than the other, they are not similar. Similarity is not only defined by engine size. Typically, a company will have three variants of say, it's 1.9l engine ranging from 74kw to 115 kw. It is not just about engine size but also about fuel delivery, engine management and inlet/outlet port differences.
