What Mpg Are You Getting In An Is220D Se-L?

[Linas.P]

Did little bit of reading for comparative reasons. One engine which sands out is Ford Duratec25/30 V6 known for being nice, reliable, happy reeving over-squared engine. Same engine makes basis for many Mazda, Jaguar cars and was developed by Porsche, later Cosworth with Ford. Same engine forms part of Aston Martin V12 5.9L (2x Duratec30) as well can be found in Noble M400 and now countless kitcars and swaps.

When it comes to specific output 2.5L version makes 170-192Hp, 3L makes anywhere between 195-280Hp in N/A application. So again 4GR-FSE is just bang on the limit what can be expected from non-turbo engine with typical power of 200-212Hp, it is as well over-squared and reliable. The extra power can be due to higher compression ration. If Lexus/Toyota would be into turbocharging game it would be quite promising engine with easy 300-350Hp on stock internals.

Generally peaking, entire GR VVTi family is pushing the limits what can be achieved on N/A petrol engines in terms of power/displacement/economy. Anything above that becomes trade-off between power and economy.
