Why is my Ferrari better?

I have discovered that some cars are better than others when they "shouldn't".
I have the Ferrari 575 GTC - (2004), and when I drive with the same parts as on my Porsche 911 Turbo BTR550 - (2008), with the exception of the exhaust and the ignition that are lvl 19 on the Ferrari and lvl 24 on the Porsche, the Ferrari comes up with a better power/weight-ratio as well as better lap times then the Porsche. The Ferrari is lvl 19 and the Porsche is lvl 24 from the start, Ferrari has 34, 35, 49, 46 whilst the Porsche has 38, 40, 52, 52 from the start. Both are RWD-cars...

Why is this? Bigger engine??
I thought that every car with a higher start lvl would always be better than the lower lvl one...

Take care everyone!

What is the turbo lvl of your cars? Coz the closer you get to the maximum lvl of the car, the better it is. For example, my Corvette ZO6 min-max lvls 25-40 can beat my ZR1 min-max lvls 32-47 and they both have lvls 35 on them. So it all depends on the parts compared to the min and max lvls of the cars.
But there are cars that are better than others for no reason at all and your Ferrari is one of them. I don't know about the Porsche...

Hope this answers your question

Well, I was under the impression that the car with the highest minimum level will be the better one, with same level parts. I mean, I've got a Focus RS with all lvl 25 parts (maximum), it's not even close to the Ferrari with about the same lvl parts...

So, in general, is it better to have a car with a maximum or minimum lvl that's closer to the parts I have?

Anyway, I'm thinking about getting myself the Ferrari 288 GTO - For me the most beautiful car ever
Anyone who have tried it?
