A few reviews of the BMW M5 haven't been too positive - it has improved as a luxury car but moved further away from the "Ultimate Driving Machine." If you have an M5 or an M6 and you agree with these reviews, BMW might have an answer. Starting with model year 2014, BMW will offer a performance package called the Competition Package. The package will bump power from 560 hp to 575 hp. Other upgrades include distinct wheels, black exhaust tips, and, more importantly, a revised suspension and a more direct steering ratio. The revised suspension should sharpen up the handling and, judging by the reviews, should be a welcome upgrade to BMW M fans. Top speed will remain governed at 190 mph and 0-60 mph time should drop by 0.1 s to 3.6 s. We'll have to wait for an official release for more details about the suspension upgrades and pricing but, considering that the M5 and M6's aren't set up equally, (full post: BMW M6 Coupe - The Ultimate Twin-Turbo M Car! ), it...
I'm finishing up a comparison post (link to introduction: Intro: Focus RS vs Golf R vs WRX STI vs Evo X ) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much. By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the...
