Comparing Cadillac's crazy classy coupes

I just returned from the press launch of Cadillac's new ATS-V, a high-performance version of the US luxury marque's entry-level compact car. While ordinary ATVs offer a choice of a 202-horspower, 4-cylinder, a 272-hp turbocharged four or a 321-hp V-6, this one packs a twin-turbo V-6 that pumps out 464 thoroughbred horses and 445 pound-feet of hard-charging torque. Starting at $62,000 for the sedan and $64,000 for the sexy coupe, ATS-Vs are available with a 6-speed manual (with Active Rev Matching and no-lift shift capability) or an 8-speed automatic with steering-wheel shift paddles. They comes with GM's latest 4-mode Magnetic Ride Control, 5-mode Performance Traction Management (with launch control), competition-spec traction and stability controls, an electronic limited-slip differential, specially-tuned electric power steering, huge Brembo brakes, and added air cooling for their engine, transmission, and rear axle lubricants. They roll on 18-inch Michelin Pilot Super Sport tri-compound summer tires on 9-inch-wide front alloy wheels and 9.5-inch-wide rears. And they will rocket from rest to 60 miles per hour in less than four seconds while delivering 16 city EPA miles per gallon and 24 highway with the automatic and 17/23 with the manual transmission. The obvious purpose of all this technology is to effectively endow Cadillac's latest V-Series models with a rarely achieved true dual personality: go, stop, and corner like race cars on a track, then sooth, coddle, and entertain like luxury cars on the way to and from the track, or work. We had ample opportunity to verify both personalities with multiple hot laps of the Circuit of the Americas (COTA) Grand Prix course, followed by a more leisurely drive on public roads near Austin, TX. Even lacking wheel-to-wheel comparisons, we believe these hot new ATS-Vs are fully competitive with their pricier German competitors, and probably superior in some ways. So now, Cadillac will offer not one but two very sharp-looking, upscale, small-volume, 2016 compact coupes, almost the same size and at similar prices, but with totally different missions: this new high-performance ATS-V and the soon-to-be-upgraded ELR extended-range EV. The key question: why? Aside from its cramped back seat and ridiculous $76,000 starting price, I loved the ELR when it was introduced for 2014.

Cadillac prices 410-hp XTS Vsport from $63,020*

Cadillac has officially released pricing for the 2014 XTS Vsport. Buyers can expect to pay $63,020 for the fleet four-door, including destination and handling fees. That kind of coin will snag you a twin-turbocharged 3.6-liter V6 good for 410 horsepower and 369 pound-feet of torque. As you likely already know, engineers have done a lot more than simply bolt a pair of turbos onto the company's tried and true naturally aspirated 3.6-liter V6. The engine uses an all-new block, strengthened connecting rods and domed aluminum pistons and is fed through a revised direct-injection fuel system. Combined, the tweaks allow the V6 to suck down 12 psi of boost.
The price tag puts the 2014 Cadillac XTS Vsport well under potential (if ambitious) competitors like the Audi S6 at $71,900, plus destination fees. A base BMW 550i will set you back $62,700, excluding destination charges, but throwing options at the German sedan will quickly see that number climb higher. You can check out the full press release below for more information.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.
