Interesting this about FI and NA engines. BMW makes great engines... but it's just their image to not bring turbos -- and that's it. Look what they do about turbo technology for diesels! Twin turbo - one for low revs, one for high revs - E60 BMW 535d. That engine got more power and torgue than their own current commonrail diesel V8!
Turbo is certainly not a bad thing in modern cars. AUDI makes the best diesels today when talking consumption/power, but also the gasolines. A chipped A3 1.8T 5 valve/cyl makes an average fuelconsumption of 7.3litre /100 gasoline, that's totally ok with 220 hp! Ofcourse it depends how you use the throttle, but the fuelconsumption can get much lower than you are able to with a V6 for example.
The pump diesels (TDI) AUDI have is the best engines you can get. |
