SRT Viper ACR is coming!

Unsurprisingly, a more track focused Viper ACR has been confirmed for production (Viper GTS-R shown). SRT CEO Ralph Gilles has previously hinted at a Viper ACR but a high-level at Chrysler has confirmed to  Motor Trend  that a faster snake is already under development. Apparently, the reason for the delay is not budget or technical difficulties facing the SRT team. Rather, it's a problem with the tires. The SRT team would like some of the sticky goodness wrapping the Corvette ZR1's wheels - the Michelin Pilot Sport Cup tires. However, Michelin wouldn't sell the tires to SRT. The Corvette team may have had something to do with it but that would be difficult to confirm. Either way, they are now pressing their supplier, Pirelli, to develop something comparable to the Pilot Sport Cup tires to be used on the Viper ACR. The development for the car and tires are expected to be done for the 2014 calendar year. Along with upgraded tires, the ACR should receive a bunch o

700 hp C7 Corvette Stingray ZR1 may be in the works!

The C7 Chevy Corvette - the Stingray - was revealed last month and the details are very promising (full post:  The Stingray is back! Details about the new 2014 C7 Corvette ) .  If we're to learn anything from the changes from C5 to the C6 Corvette, the C7 base and Grand Sport Corvettes will approach the performance of the current Z06. Carbon fibre bits and an all aluminum frame are now standard across all models. As a result the new car is 99 lbs lighter but the chassis 57% stiffer than the outgoing model. With the added help of 50/50 weight distribution and increased power, GM says the base model Stingray will be quicker than the current Grand Sport Corvette. That means the Z06 will have to move up a lot in performance and so will the ZR1. The next ZR1 is expect to use a supercharged version of the new LT-1 V8 in the new base Corvette, much like the current Corvette ZR1 formula, with about 700 hp. The Z06 may keep its massive naturally aspirated 7.0 litre V8 but with more po

2013 Mazda MX-5 Miata Club vs. 2013 Scion FR-S - A Closer Look

When Jeremy Clarkson presented the Toyota GT-86 (Scion FR-S over here) and Subaru BRZ on Top Gear (Season 19 - Episode 3), he praised them for offering affordable RWD fun. With a balanced lightweight chassis, fuel economy tires (little grip) and RWD, the car offers the same sort of fun you can have in German RWD sports sedans, but with two exceptions - lack of power and a luxury car price tag. It sounds like a good formula but the case changes in North America because the domestics have that area covered - affordable, fun RWD cars and they've even got power to boot so marketing them that way won't work. What's the selling point then? The only advantage cars like the Mazda MX-5 offer over here is lightweight handling. Motor Trend's comparison of $28k high performance two door cars that they had last year (full post:  Comparison: $28K High-Performance Two-Door ) used that advantage to choose the winner. I personally would buy the Mustang V6 if I were in the mark

Details about the new 2014 Chevy SS

Chevrolet has finally revealed its much anticipated RWD flagship sedan. As expected, the car looks nearly identical to its Australian cousin, the Holden VF Commodore SS-V and bears great resemblance to the late Pontiac G8 GXP. Unlike the Holden and the Pontiac though, the Chevy will only be offered with a 6-speed automatic as the sole transmission option. This is disappointing for those of us who prefer to row their own gears but I doubt it will affect sales. Since Dodge pulled out of NASCAR, this makes Chevrolet the only maker to have a RWD production vehicle (and a V8 one at that matter) using the same nameplate that's used for NASCAR. It, unfortunately, still isn't mechanically related to the race car but a shared name and front end is a good start. It will be offered with the LS3 6.2 L V8 making 415 hp and 415 lb-ft of torque routed to the rear wheels and a 3.27 final drive ratio. Chevy is estimating a 0-60 time of about 5 seconds but I am expecting this

Top 5 pictures from the Top Gear inbox

Top Gear posted a few funny/weird pictures of the (probably) very many that fans email to them (full post:  A small selection from the TG inbox ). There are quite a few so be sure to check all of them but here are my top 5: Nurburgring Toaster : I would have toast every day just to use this and print a map of the Nurburgring on my breakfast. Knowledge of British culture : This is one of the top 5 simply because it is true. Evolution (or lack thereof) of the Porsche 911 : I can just imagine Jeremy and Hammond fighting over this picture. Jeremy blaming Porsche's design department for being the laziest and Richard defending the design because it is aerodynamic. I do appreciate keeping heritage in car designs but it is still funny to look at. Bugatti Veyron body kit : It is both sad and impressive that someone went through all the work to do this. Lieber Nurburgring als Ehering : This translates to "Rather Nurburgring than

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

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

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 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

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
