Brabus spools up new 850 6.0 Biturbo Coupe

With a 5.5-liter twin-turbo V8 cranking out 577 horsepower and 664 pound-feet of torque, the Mercedes-Benz S63 AMG Coupe is not the first vehicle we'd figure was in need of an upgrade. But the folks over at Brabus have evidently felt otherwise, bringing the 850 6.0 Biturbo Coupe to the Geneva Motor Show this year. Now the name might be slightly misleading, but not by much: the revving heart of this beast has been bored out to 5.9 liters and its output raised to 838 horsepower (by our standards). The modified engine also includes new turbochargers, breathing apparati and a remapped ECU to produce an even more prodigious 1,069 pound-feet of torque – although to keep the whole thing from going up in flames, Brabus has limited that last figure to 848 lb-ft. The top speed has been limited to "only" 217 miles per hour to keep the tires from melting, but it'll reach 62 mph from a standstill in just 3.5 seconds. That makes this bahn-stormer blisteringly fast, though the seven-speed automatic transmission and all-wheel drive system have been left largely unchanged. Naturally that's not the end of the story, as the Brabus 850 6.0 Biturbo Coupe also features a full new carbon-fiber aero kit, wheel options ranging from 18 inches to 22, a completely refitted interior and oh, so much more. Chances are you'll never see one sitting still, so you'll want to scope it out in the slideshow of live images from the floor of the Geneva Palexpo for a closer look. Related Video:

Daimler and Volvo could jointly develop internal combustion engines

BERLIN — Luxury German carmaker Daimler and Volvo, owned by China's Geely, are considering cooperating to cut the costs of developing combustion engines, a magazine reported on Sunday, citing unnamed company sources. The Automobilwoche weekly cited a Volvo manager as saying there were initial talks with Daimler, but no concrete plans, while a company spokesman said it was too early to talk about firm projects, although it was not excluding anybody. A Daimler spokesman said the company's cooperation with Geely, which owns a 10% stake in the German carmaker, was developing in a positive way, but declined to comment further. Global tariffs, accelerated by a trade war between China and the United States, as well as higher investment requirements for electric and autonomous vehicles, are forcing carmakers to seek new ways to cut and share costs. In October, Volvo said it would merge its engine development and manufacturing assets with those of Geely, creating a division to supply in-house brands and also potentially others with next-generation combustion and hybrid engines. Automobilwoche said this new division would start operating by the end of March, which could be a possible starting point for cooperation with Daimler, while a further step could be a partnership to develop electric power trains. Geely and Daimler have said they plan to build the next generation of Smart electric cars in China through a joint venture and the two companies are also cooperating on a premium ride-hailing service in China. Geely bought Volvo Cars in 2010 from Ford, allowing the Swedish brand to operate on an arms-length basis. But in recent years, it has deepened cooperation between the two brands. Volvo already supplies engines to some Geely-branded vehicles, sharing technology through Geely's Lynk brand. Both companies share and develop common vehicle platforms.

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).
