2016 BMW 640i Convertible Test - A Closer Look

"It pounces on corners, tracks flat through the apexes, and devours the straights with a burly snarl from the V-8. It laps up freeway kilometers at triple-digit speeds, the suspension digesting ripples and dips so thoroughly that the body remains almost inert. All the driver has to do is aim the 645 and it goes there. Fast." Sounds great, right? Absolutely, except for the fact that it isn't about this 640i. Keen BMW fans would probably be fast to note that this 640i doesn't even come with a V8. The above is fro m a review of a 645Ci that was published back in January 2004, 12 years ago. This new review , though, was.. let's be kind and say less flattering. As seems to be a pattern now for all BMW's, except the 2-series and M models, there's lots of disappointment. "Our car, equipped with BMW’s M Sport package, offered what seemed to be a slathering of faux sportiness." It only managed 0.86 g on Car and Driver's 300-ft...

Sabine Schmitz in a Porsche 911 GT3 R at the Nurburgring

If you're one of those people who complain about not enough action and passing in racing (I don't blame you), the video below may just restore your faith. Sabine Schmitz, famous Nurburgring taxi driver, race car driver, and now one of the new presenters of Top Gear UK (we forgive her for that), is piloting a GT3 R in the video below at the Nurburgring, in the wet. And it's awesome.

911 GT3 vs Nissan GT-R Track.. in the WET

Ever wonder how a 911 GT3 might stack up against a GT-R Track Edition.. in the wet?  The GT-R comes with Dunlop SP Sport Maxx GT 600 DSST CTT tires and the GT3 comes with Michelin Pilot Sport Cup 2. The Dunlops are classified as Extreme Performance Summer tires on Tire Rack while the Michelins are Streetable Track & Competition so the GT-R should have the tire advantage in the wet. The GT-R obviously has the traction advantage due to being AWD but remember, no 2WD car has more traction than a 911, assuming comparable tires, due to the engine placement so don't place your bets just yet. Watch and find out who wins, but don't forget to comment below!

Falken Azenis RT615k+ Street and Track Review

Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax  set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f...

2007 Saleen Mustang S281 SC Super Shaker Track Review

"Who's your green student today?" asked a friend and instructor at the BMW Club Atlantic Advanced Driver Training (HPDE) weekend in June this year. I said: "The Saleen." The response was: "Oh, boy." Mustangs, generally, have a reputation for being more power than chassis. Mustang drivers have quite the reputation for.. how to put this nicely? Taking advantage of said power/chassis imbalance. To make matters worse, this particular Mustang was a supercharged Saleen, with a honkin' Shaker scoop sticking out of its hood. Did I mention it was also a convertible? And the owner was someone who's never been on track before but clearly has the speed bug. Having had a Mustang for years and driven a few on track, they don't scare me - generally speaking - but the combination of being convertible and supercharged with a new and excited owner worried me a little. Nevertheless, I shrugged it off and got excited about chatting with the owner to find ...

Limited Slip Differentials - The Basics

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...

All Mainstream AWD and 4WD Systems Compared and Explained

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,...
