Mercedes?

Maybe the SLR if you're looking for a heavy weight with a good pwr.
Other than that most of them are pretty heavy.
The SLK might be worthy of checking out but I haven't done that so I can't really say.
BMW?
Nothing really comes to mind in a pwr discussion.
I love the BMWs in the game, m3, m coupe, etc. but most of them are pretty much average with no unusually light or fast cars to mention (if race cars were the subject it would be different

).
The torque to weight ratio on the diesel 120 is great. 👍
Check it out if you have the time & Cr.
RUF?
Excellent brand.

Standouts are across the board.
The 3400s is a great MR car with an excellent balance of power to weight. Handles well and seems to be good with braking too.
The CTR2... I don't know this car very well at all... Time for some testing.

The RGT is one of my favorite cars in the game, its PWR is nothing to get crazy over but the car's potential is amazing.
... BTR & Yellow Bird...

These are the monsters of the group. Light weight and powerful, they are some of the best cars in the game.
Well,
That's my take on the companies mentioned.
However, I just want to add that one car hasn't had much attention paid... The RX7. 👍
Any generation, any year- they are all powerful and light weight.
