Cadillac CTS Vsport laps the N"urburgring in 8:14.10 [w/video]

You don't have to be German to test your car at the Nürburging. You just have to be serious about beating the Germans on their own home turf. That's why Nissan tests its GT-R at the Nordschleife to challenge the Porsche 911, and why Cadillac - which is no less serious about putting up a fight to German performance sedans - has returned to the 'Ring once again with its latest.
This time it's the turn of the new CTS Vsport, the sportier version of Cadillac's new mid-range sedan that aims to bridge the gap until the arrival of the next CTS-V. So how'd it fare? At the end of what we're sure was an exhaustive test session, the new CTS Vsport clocked a time of 8:14.10.
To put that into context, General Motors points out that the time places the new sedan six seconds ahead of the first-gen CTS-V, whose 400-horsepower V8 engine was actually less potent than the Vsport's new 410hp 3.6-liter twin-turbo V6. That's still a good fifteen seconds slower than the outgoing CTS-V that clocked a 7:59 in 2009 with its 556hp supercharged V8, but only a second behind the E60-generation BMW M5 with its high-revving 500hp V10.

Cadillac's 4.2-liter Blackwing V8 to die with the CT6?

Cadillac's 4.2-liter twin-turbo Blackwing V8 debuted only last year, popping up in the CT6 V-Sport — now the CT6-V — with 550 horsepower and 627 pound-feet of torque. The engine's been stymied in every attempt to power a different Cadillac model since then. Its only two use cases have been a first and second run of the original, limited-edition super sedan and the CT6 Platinum V8 trim at a slightly detuned 500 hp and 553 lb-ft. Motor Trend cites "a highly placed source at GM" as saying that the Blackwing won't go into the coming high-performance version of the CT5-V nor in the next-gen Escalade. Left without options, there's a chance the Blackwing will die with the CT6, itself a sedan with its grille on the executioner's block just waiting for the bite of an ax that might or might not shortly fall. Cost-cutting has been tagged as the reason for this misfortune; Cadillac's sales malaise and lack of clarity as to how to turn sales around led GM to downsize the brand's allowance. The parent company chose to build the new CT5 on the Alpha platform used for the erstwhile ATS and CTS instead of the Omega platform underpinning the CT6. Along with that choice, the MT report says expense reasons nixed fitting the Blacking V8. We know the lower-tier V series CT5 will work with a twin-turbo 3.0-liter V6 making 355 hp and 400 lb-ft. When we heard spy video of the upper-tier V series CT5 out testing, the engine sounded like the 6.2-liter supercharged V8 that would be a carryover from the last model.  The XT6, also rumored to get some V sauce, simply can't fit the V8. Instead of sitting on the Omega platform as once planned, the XT6 rides on the C1XX architecture under other GM products like the Buick Enclave and Chevrolet Traverse. The C1XX engine bay doesn't have room for a stouter V6, much less a hi-po V8. The next-gen Escalade ruled itself out due to price issues in back, not in front. MT writes that the independent rear suspension supporting GM's next-gen full-sized SUV quartet has burned through cash in development, putting engineers a few direct deposits short of the funds needed to massage Blackwing installation. Earlier this year at least one report said the twin-turbo DOHC V8 could serve the top-spec next-gen Escalade. More recent reports of a performance-heavy next-gen Escalade have predicted the 6.2-liter supercharged LT4 V8 from the Chevrolet Camaro ZL1 and Corvette Z06.

Why the 2015 Detroit Auto Show will be the best since The Crisis

The Detroit Auto Show clearly has its swagger back, and the 2015 edition will be a veritable feast for the enthusiast senses. We're talking serious performance, and it will be exhibited in a variety of forms. Sports cars. Supercars. Muscle-bound luxury cars. They're all set for splashy debuts in January in the Motor City. It's another signpost that companies have recovered from the global economic crisis that gripped the industry from 2008-09. For a while, automakers played it safe at Detroit and other shows. Environmentally friendly cars were important, especially for General Motors and Chrysler that were living on loans from Uncle Sam. Ford, Toyota and other companies generally focused on their best-selling or core models. With a few notable exceptions, recent auto shows have been a bit more buttoned-down than in the past. Boring probably isn't the right word, but austerity has been reality. That's changing. Car companies are making money. Sales are up. Aside from the many nagging recalls – and they are notable – the industry now has the time and energy to make performance cars a priority. That will be offered in hard evidence in Detroit. A year from now when we look back at this auto show, we'll sum it up with one word: Horsepower. But make no mistake, this isn't frivolous. Sports and luxury cars are expensive. They're profitable. They boost images and highlight strengths. With that in mind, here are five significant performance-oriented reveals to watch for when the show kicks off in less than two weeks. 2016 Acura NSX Acura's reborn NSX is a strong bet to earn plenty of votes for our Editors' Choice awards. It's one of the most anticipated – and strung-out – reveals of the year. Think back: we actually saw an NSX concept at the 2012 Detroit show, and Acura has spent the last three years teasing the car in a variety of ways. The slow burn, however, means we know a lot about the NSX. It's will use a mid-mounted twin-turbo hybrid powertrain and run with all-wheel drive. It will also wear an innovative zirconium e-coat paint, a new paint process that Honda says is more environmentally friendly. Honda has also said it will build the new NSX in Ohio, where a large part of the car's development work has been done. The original NSX was produced from 1990-2005 and helped establish Acura's performance credentials in the United States. It was a landmark car and a shot across the bow of Ferrari, Lamborghini and others.
