The caveat here are the new hybrid gasoline engines which dramatically improve

than an equivelant engine size
diesel.
However, on average a

than its equivelant engine size

> MPG and running costs - The

petrols — a 99bhp 1.4 - litre and 118bhp 1.6 - litre — as well as a 108bhp tune of this 1.6
diesel and a very meagre sounding 89bhp 1.4 CRDi, which majors only on list price with worse fuel economy
than the 1.6 and a yawning 13.5 sec 0 - 62 time; unlikely to be called upon in Top Trumps, but it will translate into overtaking frustration in the real world.
From then on there were the also the 0.9, 1.0, 1.2 lt turbo engines by most carmakers but since the emissions tests are now going to be based on real life conditions and not lab conditions, even those displacements apart from the
diesel ones will prove to pollute more
than what is claimed and as such, especially in the non-turbo small
petrol engines the only way to meet the emissions is to upsize in order also to maintain and improve performance.
The ST is also available with a 183bhp
diesel engine that, with 295 lb ft available from 2000 to 2750rpm, is even torquier

Poised to be the most dynamic Bentayga yet, the V8

than Mazda's current Skyactiv - G
petrol, pulls cleanly from tickover in high gears if required, and doesn't have a hint of
diesel - style rattle.
In contrast, the torquey 2.2 - litre
diesel effortlessly puts in an 8.1 - second time and matches the
petrol unit's 130mph top speed (eight seconds dead and 132mph for the Fastback) and in reality, for most drivers, it will be far quicker
than the
petrol units for more of the time, as it has a usable mid-range obviating the need for revs.
The

petrol for the best performance or the 300h hybrid, which is cleaner
than the thirsty 200t, but can still only manage 57.6 mpg.
The Auris has low claimed CO2 emissions, too, and this means it stacks up well as a company car — the Benefit - in - Kind (BiK) bracket is lower
than for the
