So what did they do to get that extra hp? :roll:

 

[hooolala]

you mean the extra 1 hp?

hmm... use higher grade of gas?

Its marketing, cant have the "lowly" Rav4 on par with the Lexus. 8)

Its a different engine in the 07 RX350, the 06 model was the RX330. Lexus always use the last 3 digits as engine displacement. The RX350 has a 3.5 liter engine and the old RX330 was equiped with the 3.3 liter engine.

I think he means "Why does the same 3.5L V6 rate as 269hp in the RAV4, 268hp in the Avalon & Camry, 270hp in the RX350 and 272hp in the ES350?"

I'd chalk up their slight variances to ECU programming, compression ratios and different transmissions.

We won't count the IS350, because we already know the dual direct injection pumps it up to a marvelous 306hp...

plus Lexus's use Premium, hence slight advantage. IS350's engine is completly different ballgame...

 

[Quickdtoo]

Using premium fuel is a requirement due to the higher compression ratio, not a performance enhancement in itself as many people think. Use of premium fuel in an engine not designed for it will result in a performance decrease or no change at all. :wink:

You do realize that we're talking about the same engine here, right? The V6 in the Rav4 and RX350 is the same.

 

[flyingn]

mhgsx is correct..
