Cadillac to Corvette: You’re not getting our twin-turbo V8 engine

NEW YORK — Cadillac president Johan de Nysschen bluntly shot down rumors his brand's powerful twin-turbo V8 is also headed for the Chevy Corvette. Speaking Wednesday at the New York Auto Show, he said: "Just quit the speculation it's headed for Corvette. It's not." The 4.2-liter V8 cranks out 550 horsepower and 627 pound-feet of torque in the Cadillac CT6 V-Sport, which debuted at the show. With that kind of performance and the fact the engine will be hand-built at the General Motors Performance Build Center in Bowling Green, Ky. — at the Corvette factory — led enthusiasts to presume the engine would eventually be under the Vette's hood. De Nysschen, however, argued the engine will also focus on levels of refinement, rather than the Corvette's raw, visceral dynamic. "I think Corvette wants a different kind of character," he said. In fact, the V8 is set to be only for Cadillacs, de Nysschen said, giving the luxury brand its first exclusive engine in years. "It's a matter of being a thoroughbred luxury car," he said. "It's really only a luxury brand that could recoup this [development] cost." A version of the engine making 500 hp and 553 lb-ft will also be used in other Cadillac models. De Nysschen declined say which vehicle will get the engine next. The new V8 uses a "Hot V" configuration more common to German performance cars, and has direct injection, electronic wastegate control, active-fuel management and stop-start technology. It teams with a 10-speed automatic transmission and fits either rear- or all-wheel drive systems. With a new mid-engine Corvette — and potentially more versions of the existing generation Vette — on the horizon, speculation pointed to the sports car getting a twin-turbo powerplant of some sort (V6 rumors also have floated), and the Cadillac 4.2-liter seemed to fit on paper. According to de Nysschen, that won't be the case. Still, even though the Cadillac boss says this specific engine won't go to Corvette, it's hard to not think some version of this engine, perhaps in a different displacement, could find its way under the hood of the Vette at some point in the future.

Cadillac: The standard of what?

Cadillac's tagline "Standard of the World" goes back to 1908 when it won the Dewar Trophy. While you might think that the moniker and the trophy have something to do with a feat of racing and daring-do against a cadre of British, French, and German marques, it's nothing of the sort. Rather, Cadillac achieved the trophy because of interchangeable parts. The parts they were producing back then were so well-made that Henry Leland, who established Cadillac, was able to disassemble three Model Ks, mix up the parts, and then put together three functioning cars. This amazed the Brits who handed him the trophy, and the "Standard of the World" was born. During the past several months, Cadillac has been producing news releases that would seem as though the company is the Standard of the World: "Cadillac Global Sales Rise 44.2 percent in January ... 18 percent in February ... 22.1 percent in March. . .40.9 percent in April ... 33.8 percent in May ... 7.2 percent in June." Like the Dewar Trophy being about manufacturing not performance, things are not necessarily what they seem. That is, Cadillac's growth is predicated on performance in China, not in the US. Through June, its China sales are 80,357 vehicles for the first five months of 2017, versus 72,073 in the US. The China number is a 75.4-percent year-over-year increase while the US number is a 1.6-percent decrease. For the entire globe, Cadillac has sold 164,174 vehicles. Of them, 65,250 were the XT5. That was followed by the ATS, at 34,277 units. In the US, the XT5 is doing reasonably well, as it has moved 29,798 units during the first six months. The ATS, conversely, is doing not particularly well, as it is down 26.2 percent with sales at just 7,209 for the year so far. To put that into some sort of context, know that Cadillac has sold 7,370 copies of the generally derided XTS, which is down 24.7 percent. The CTS is down 36 percent at 5,059 units, and the only other car in the lineup (we'll pretend that the ELR doesn't exist anymore and it shortly won't), the CT6 sedan, is up 172.7 percent – but they have sold only 5,397 CT6s. While Caddy talks a good game about competing with the likes of the BMW 5 Series and the Mercedes E-Class, know that those two sedans have been sold 17,036 and 20,783 times this year in the US respectively. So what is Cadillac chief Johan de Nysschen to do? According to Reuters, it is to cull the lineup.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
