2020 BMW M3 Pure to be manual, RWD

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

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 cover in a future post.

Bridgestone Potenza RE-71R Track Review

For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are:

1. They grip as well or better than most R comps.
2. They don't wear as quickly as R comps if driven occasionally on the street.
3. They work better in the rain than R comps.

The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine.

In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman at Tire Rack who has gone faster on RE-71R's than NT01s. In a Mustang (his own, not…

Stock Suspension S197 Mustang With Square 305/30/19's

If you've had any doubts about whether or not they will fit, fear not! You absolutely can run square 305/30/19's. I had a lot of doubts before pulling the trigger, even more so when the wheels where on the car. The tires do poke out a bit and I figured rubbing is all but guaranteed at full compression but I couldn't be happier I trusted APEX and those on here who have run it.

Here's what you need:

1. Camber plates: I have MM C/C plates and they are maxed out at -2.3 deg with the stock struts. I have been running them for years with many track days without issue.

2. 1"/25 mm spacer: I have Motorsport-tech 1" spacers and they look like high quality units. There is maybe a 1/4 inch clearance in the back so you can't go any narrower than 25 mm. http://www.motorsport-tech.com/adaptec/car/ford_s and you want Design 2.


3. Elongated studs: your best bet is to get the FPP hubs with elongated studs instead of reusing the old one. Bearings are consumables anyway so…

This Lanzante Porsche 930 is powered by a GP-winning F1 Engine

Whenever I hear of an outlandish 911 build, I always wonder what hardcore 911 would think. In my experience, they tend to love tradition and preserving the 911 legacy. This car breaks two of the holy trinity of classic 911's; rear engined, flat-six, and air-cooled. It is still rear engined but it uses a V6, water-cooled engine. But I can't imagine a single 911 fan being upset about this.

You see, this isn't just any water-cooled V6 engine. It is a Formula 1 twin-turbocharged 1.5 litre V6 out of a McLaren MP4/3 F1 car. Further preserving the Porsche-ness of this build, the engine was built by a partnership formed between Porsche and TAG to provide engines for McLaren F1 team. Porsche was responsible for the technical burden of design and engineering and TAG financed the effort and stuck its name on the engine as "TAG turbo" since McLaren didn't want Porsche's name on their F1 car.

Lanzante first revealed the car in October last year shortly after the annu…

Brabham BT62 Breaks Bathurst Lap Record

It wasn't long ago that Brabham announced that it was returning to competition with the BT62 to compete at the World Endurance Championship (WEC) and Le Mans. They also announced that they will be building a road-legal version of their mighty BT62, likely to qualify for the GTE class requirements so it can compete at Le Mans. Capitalizing on that, Brabham was planning on taking a BT62 for demonstration laps in the build-up to the Liqui-Moly Bathurst 12 Hour race that's running this weekend, but they gave the people a lot more than a few hot laps.

With minimal testing on Thursday and with just four laps on Saturday, conditions were good so the BT62 test driver Luke Youlden went for a flying lap. That flying lap set a new track record of 1:58.67. The lap time is a verified clocked time, but it is labeled "unofficial" because it wasn't set during a competitive session. The previous lap record was 1:59.29, set by an unrestricted Audi R8 GT3 race car last year in tes…

Everything You Need to Know about the $60k Mid-engine C8 Corvette

By now, you've probably heard one of the most incredible things about the new Corvette. It isn't the mid-engine layout. It's actually the price. It will start just under $60,000 USD (and under $70,000 CAD according to GM Canada Media website). Of course, that number alone means nothing if you aren't getting something special. So the question is: what are you actually getting for $60k? Let's dive right in.


The Drivetrain

Although most publications were anticipating the new Cadillac twin-turbo V8 called "Blackwing" until recently, I predicted last October that the base engine will likely be a revised version of the LT1 V8 in the current C7 Corvette "making anywhere between 480 and 500 hp." The C8 Corvette Stingray (at least until Z versions start coming out) will be powered by a revised 6.2 litre V8 named LT2. The engine will make 495 hp and 470 lb-ft. torque with the Performance Exhaust. The base version hp isn't announced but it will likely …
