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 power. Fuel economy probably will not drop with the increase power. GM will make sure that the Z06 and ZR1 are differentiated enough in terms of hp. As a result, the ZR1 will maintain its hp advantage. The Z06 should pack around 580-600 hp and the ZR1 should be close to or even crack 700 hp.

According to GM, the new LT-1 V8 is expected to make at least 450 hp in the base Corvette. Before the Camaro ZL1 numbers were released, it was expected to have around 550 hp which means that "at least 450 hp" should translate to a power rating of 460-480 hp. The Z06 and ZR1 are expected to be released about a year after the base model to let the base model establishes itself and get sales. Much like the development of the C6 Corvette, the Z06 will probably be released first, followed by the ZR1.

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...

Ford Focus RS vs Subaru WRX STI vs Mitsubishi Evo X MR

All these cars have one common Achilles' heel. The engines sit entirely ahead of the front axles; a great family recipe for understeer. Then tell the front tires - already taxed from trying to keep that front engine sitting outside the wheelbase from going straight - to put some power down and you can only make matters worse. There are ways to mitigate the understeer with suspension tuning, of course, but the toughest part is power-on understeer. I don't want to get much into tires, but the thing to remember is that because tires have a certain "grip budget" - how much total grip they can hold/generate before they let go - when you get on the power in a car that sends power to the front wheels (FWD or AWD), you will rob some of the precious grip you were relying on to turn the car in order to put all or some power down. You'll run out of front lateral grip sooner than you would have otherwise, as a result. Worse yet, because of the unideal en...

2016 Mustang EcoBoost Track Review

Photography by: Graham MacNeil Ford really wants to sell you a Mustang with a turbo four cylinder. They started by derating the V6 engine in the 2015 S550 compared to the 2011-2014 S197 V6 to make the EcoBoost 2.3 litre more differentiated. Then, they offered a performance pack on the EcoBoost but not on the V6. Now, they killed the V6 all together for 2018 and will only sell you a V8 or this EcoBoost. I love a good V8, everyone who knows me knows that. This is a Mustang, which means it needs a V8. If those aren't enough reasons, I always prefer natural aspiration over forced induction. That's three strikes against the EcoBoost-powered Mustang. But I'd be lying if I said the idea never intrigued me. It's the lightest (if you account for features). It has the best weight distribution. It has the same great chassis as the GT. It's very affordable and it has a lot of potential to make more power. Aftermarket? Endless support. There's plenty of good about it....

Why an Open Differential Doesn't Work on Track

C7 Corvette Grand Sport... doing a burnout with a proper diff - Graham MacNeil  © I wrote a tech post comparing various open and limited slip diffs for a comparison and I found that a lot of people were asking questions. To simplify and make it easier to read, I decide to break them up for a future tech article about handling. Make sure to stay tuned for two posts on limited slip diffs this week!. WHY DO YOU EVEN NEED A DIFFERENTIAL? A differential's job is to allow two wheels on the same axle (or two axles in a 4WD drivetrain) to spin at different speeds so a car could smoothly go around a corner. Why do the wheels need to spin at different speeds? Each wheel on a car has to travel a different path to reach the end of the turn. You can see that for yourself every time you drive on snow covered roads or muddy trails.
