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!

2004 Audi TT 3.2 Quattro DSG Track Review

Before getting into this, I have to confess something... I had never driven an Audi TT before. Not until this one, anyway. But that hasn't stopped me from forming an opinion about it from the comforts of my own couch while reading and watching reviews online. After all, if you've never done that, do you even know what the point of the internet is? Now, we all interpret reviews differently. Call it confirmation bias if you will, but if you like a car, you'll read a review and look at the positives as what makes the car great and the negatives are but a few quibbles you have to live with. If you don't like a car, the positives are a few things the manufacturer got right while screwing up everything else. It's a bit harsh to put the TT in the latter category, but that's where it ended up for me... I never took the TT seriously. The problem with the TT for me isn't that it's a Golf underneath, per se. There is nothing wrong with a performance car sharing a

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

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

Limited Slip Differential Types Compared

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
