BMW M Still Committed to Manuals

The last generation BMW M5 (F10) was the beginning of the end for BMW M manuals in the M5. It was offered without a manual around the world but, after relatively high demand, BMW offered a manual in the US and Canada. The current BMW M5 doesn't offer a manual at all, not to mention going AWD. That doesn't bode well for purist fans of the brand since BMW M has clearly thrown crucial traditions of the brand (i.e. RWD and manual) to the curb in the name of performance and/or efficiency. It looks like that isn't the end of all manuals, though, at least not yet. BMW’s M division boss Frank van Meel told Car and Driver at a press event a couple of months ago that the brand is still committed to manuals. Presumably, he was referring only to the M2 and M3/M4 since all other M cars including the M5 and "SUV" M cars like the X5/X6 M are only offered with automatics now and you can bet that the M6's replacement - the M8 - will be offered with only an automatic. As ...

550 hp V8 Cadillac CT6 V Coming in 2019

Cadillac's largest car - the not-quite-a-flagship CT6 - is becoming a little more flagship-y by getting the full V treatment like you can get on the CTS and ATS (for just one more year before they're axed in anticipation of replacements, so grab them while you can). Cadillac calls the CT6 top-of-the-range but won't call it a flagship, clearly wanting to leave that distinction to a larger and/or more grandiose vehicle in the future. It was previously announced in March earlier this year to be getting a high dose of performance enhancements, the highlight of which is a new twin-turbo V8, and was going to join the line-up as Cadillac's skim-V models called V-sport. Think of it like M-performance packages from BMW vs full fledged M models, the only difference being V-sport models typically get unique (and much more powerful) engines. But just a couple of weeks ago, Cadillac announced that it will make it a full-fledged V line model, making the car inch a bit higher in p...

2020 Mid-engine Corvette C8 - What You Need to Know

Rumours of a mid-engine Corvette have been around basically since the C2 Corvette, the first Stingray. I've heard some people argue that the Corvette is already mid engine because the engine sits almost entirely behind the front axle, making it mounted midship. But everyone knows that the classic definition of a midengined car is that of an engine mounted between the seats and the rear axle, not the front axle. That's what everyone pictures if you say "mid-engine". Worse still (for the Corvette), a true midengined layout has a lot more traction - all else being equal - than a front-midship mounted engine like the current Corvette, no matter how far back it is mounted. Chevy knows this, and there has been no shortage of Corvette mid-engine concepts for decades. This time, however, it's different. For one, manufacturers these days tend to keep very special/high performance models under wraps for a very long time during development, only revealing them when th...

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...

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....

2015 Mustang GT breaks into the 11's in the 1/4 mile!

It went 11.77 seconds to be exact and past the traps at 116 mph and that's with minor modifications. The modifications were courtesy of the folks at Ford Racing. They recently got a hold of three 2015 Mustangs, one with the 2.3L EcoBoost engine making 310 hp and two GT's with the 5.0L V8 making 435 hp. The power modifications are minor for two of the three Mustangs. The 2.3 EcoBoost gets a "Prototype Off-Road Exhaust" which most likely means there are no catalytic converters or "cats", a more free flowing exhaust and a tune. One of the GT's gets the same off-road exhaust treatment and a tune plus "ARH Cobra Jet Long Tube Headers". In the video, they say they did "a few changes to the air intake system but basically these are close to what any consumer can buy" so they may have included a K&N drop-in filter which FRPP Performance Packs for the 2014 Mustang GT included or an aftermarket CAI with a cone style filter....

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...
