2020 BMW M3 Pure to be manual, RWD

By
A couple of months ago, I posted about how the 2020 BMW M3 (code named G80) will bring more than 500 hp and AWD . At that point, I figured all hope was lost for a manual M3 or M4, despite an earlier report that BMW M is still committed to manuals . Thankfully, it looks like hope is fully restored or - better yet - replaced with full expectations of a manual, thanks to an interview by Car Magazine. If you were waiting for a 500+ hp AWD beast, fear not. It is still coming. But BMW M boss Markus Flasch just confirmed to Car Magazine that an entry level version for the purists will bring lower horsepower, a manual stick shift, and RWD. They are code named M3 Pure or M4 Pure internally and will pack "only" 454 hp. According to Car Magazine, this is because BMW does not have a manual gear box that can handle the full output, but I'm sure it also has something to do with hierarchy. It will still come with an electronic limited slip differential like the current M cars...

Limited Slip Differential Types Compared

By
BMW M2 equipped with an eLSD - BMW © A few weeks ago, I posted about traditional clutch-type limited slip diffs (LSD's) and how they work. You can read about those in the previous post: How Limited Slip Diffs Make You Faster on Track . But as you might know or have learned from reading the article, they aren't without their faults, which means engineers are always working to get around those limitations. You may not be surprised to learn that something like the Ferrari 488 GTB doesn't use a traditional limited slip diff, but it's not limited to super cars, far from it. Cars like the Golf GTI, the Civic Type R, various Mustangs, Corvettes, and BMW M cars, and even the Lexus RC F and GS F, all avoid a traditional limited slip diff in favour of one of these technologies. To keep things simple, I'll focus on two wheel drive vehicles. The vast (vast) majority of principles apply to all and 4 wheel drive vehicles, but there are some subtle differences that I'll...

All Mainstream AWD and 4WD Systems Compared and Explained

By
Mitsubishi Evo X GSR at Atlantic Motorsport Park - Kevin Doubleday  © If you live in Canada or the US, you'll find that plenty of people hold sacred the terms '4x4' and '4WD' to describe a 'true 4x4', where you have a butch transfer case with a low speed, perhaps a body on frame chassis, and ideally a solid axle or two. I'm not sure how that translates to the rest of the world. My extensive research into the motoring industry in Europe (which exclusively consists of watching Top Gear and The Grand Tour...) concluded that most people across the pond simply refer to any vehicle that is capable of sending any power to all four wheels as a 4WD vehicle, further muddying the waters. Where I grew up, 4x4 was more or less synonymous with 'Jeep' so that's not much help either. However, despite all various systems attempting to do the same sort of thing - distribute power between all four wheels instead of two - not all systems are created equal,...

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

By
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...

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

By
I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would ...

Limited Slip Differentials - The Basics

By
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...
