Obviously 458 has shorter gear ratios in comparison to 911 Turbo S or Mercedes AMG SLS. Its engine revs up to 9100 rpm (instead of 6500 - 7000 rpm of 911 turbo or mercedes).
Hmm... You need to get the facts right I am affraid.
Max. revs on SLS AMG are 7200rpm, same on 997.2 Turbo S.
Ferrari is using very short overall gear ratios on 458 to tame true lack of torque on low revs. Period. High reving engine do not need to use gear ratios that short. It was a Ferrari deliberate decision.
Also you MUST order all very expensive CARBON FIBRE items on 458 to get close to official weight claim by Ferrari. Otherwise in standard trim 458 is 1600kg car. Few members here even measured weight of their 458... So, in other words-yes, 458 is extremly fast on the Ring-when it costs above 250K € in Germany(with all CF options). We here on rennteam already discussed this fenomenon few times...
Do not get me wrong 458 is probably the best sportscar on the market currently.
Kresi,
This is a simple table showing up :
1) Speed at 1000 rpm for 458, California and F430
2) Max speed in each gear at rpm power peak

Everybody can simple notice that 458 gear ratios have been shortened (mainly final drive ratio was changed) in comparison to California BUT max speeds at power peak rpm for each gear are the same. This means gear ratios have been only adapted to longer rpm range of the 458 and to the facts it has 20 inches rim option (Increase rims diameter increase speed at given rpm so you have to short gear ratios).
Top speed can be reached under power peak rpm, this is a bit strange for Ferrari models (see F430, 360 Modena, F40, F50 etc etc.) that normally reach top speed over rpm peak power.
About 458 options, I don’t understand the point. Also a stock manual 997.2 turbo will be slower than a 997.2 PDK turbo S and you pay for both PDK and extra horsepower.
Cheer
PS. the only options that really help is 20 inches option rims that help to reduce unsprung mass improving acceleration and tyre – track contact.
