This is the new BMW M4 which is powered by a twin-turbo 3-litre straight six making 425 hp and 406 lb-ft of torque which is 11 hp and 111 lb-ft of torque. While that is a healthy upgrade, specially the increase in torque, the engine noise is rather disappointing.. Below is a video showing a 2015 BMW M4 start up and rev. You can actually hear someone in the background saying that it sounds like a Prius. Many diehard M3 fans and auto enthusiasts in general were bemoaning the switch to a turbo engine and now there's another disappointment, the engine noise. If you have a laptop, I recommend plugging in good speakers, preferably with a woofer, or at least head phones because laptop speakers will make it terrible.

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load
