2016 Mercedes-Benz C450 AMG Sport bridges the gap between C300 and C63

Mercedes-Benz is looking to its new C-Class for the second member of its new AMG Sport line, unveiling the C450 AMG 4Matic at today's 2015 Detroit Auto Show. Like the GLE450 AMG Coupe that debuted in early December, this particular C-Class bridges the gap between the standard C300 and the new Mercedes-AMG C63. Considering this, the C450 builds on the standard C400's 3.0-liter, twin-turbocharged V6, rather than getting a bespoke, high-performance engine. Output is up from 329 horsepower to 362 ponies, while torque is turned up from 354 pound-feet to 384 lb-ft. The result of these upgrades is a zippy 0-60-mile-per-hour sprint of 4.9 seconds and an electronically limited top speed of 155 mph. Those figures are identical to the Audi S4, while the BMW 335i xDrive is just a smidge quicker to 60, getting there in 4.8 seconds (the Bimmer is, however, limited to just 130 mph). Shuffling the 3.0-liter's grunt to a 4Matic all-wheel-drive system is the responsibility of Mercedes 7G-Tronic automatic gearbox that, despite not being a member of AMG's Speedshift dual-clutch family, still has its own mind for performance. Along with a quick-shifting, automatic Sport Plus mode, the C450 has a full manual shifting mode that, notably, will not automatically upshift, even when the engine is bouncing off the rev limiter. The C450 AMG hasn't only had its straight-line abilities boosted. Mercedes saw fit to include an AMG adaptive sport suspension with three-stage adjustable dampers, which have been pilfered from the C63 AMG. Paired with the aforementioned all-wheel-drive system, which can send up to two-thirds of its power to the rear axle, it's a fair to say this particular sedan should be one of the brand's more agile and entertaining. Beyond the mechanical bits, Mercedes has beefed up the exterior and interior aesthetics for its second AMG Sport model. The exterior has been touched up with new, staggered 18-inch, five-spoke wheels (or optional 19s), a more aggressive front fascia, a new rear bumper with a matte iridium diffuser, distinctive AMG badges and plenty of chrome and gloss-black elements. The cabin, meanwhile, is home to black MB Tex upholstery with red contrast stitching on the dash and doors, while AMG-specific upholstery lines the sport seats. The flat-bottomed, three-spokes steering wheel, meanwhile, is finished in Nappa leather. We'll have more on the 2016 C450 AMG Sport, including live images, coming soon from the floor of the 2015 Detroit Auto Show.

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.

Cigarette Racing unveils the AMG GT S-inspired 50-foot Marauder

The Cigarette Racing stand at the Miami Boat Show this morning hosted the latest in the eight-year collaboration between Mercedes-AMG and Cigarette Racing: the AMG GT S parked next to the fast-boat it inspired, the Cigarette Racing 50 Marauder GT S Concept. The vinyl ester resin and fiberglass go-fast boat is more than a matching Solarbeam yellow paint job with the coupe that inspired it. Like other carmakers who have partnered with companies outside the industry - such as Nissan's recent tie-up with NASA - there's an exchange of technology involved; Cigarette said that working with AMG on composites and bonding helped them drop 1,000 pounds off the Marauder GT S Concept compared to the standard Marauder twin-engine, which comes in at 14,200 pounds. Customers who order standard Marauders can request the weight reduction (for a price), but we were told that unless they plan to spend most of their time above 100 miles per hour, the extra weight contributes to a smoother ride. Mercedes head designer Gordon Wagener penned the exterior paint job and worked with Cigarette to design the cockpit trim, which would have seen him in familiar surroundings: Cigarette Racing owner Skip Braver is a long-time AMG customer, and the boat company based its bespoke department on the AMG Design Studio in Affalterbach. Every one of its boats is handbuilt in its factory in Opa-locka, Florida using some of the same processes seen in automaking, like bar codes to track the progress of hulls and components, computer controlled paint samples with digital files that can be sent around the world for matching, and doing all the stitching in-house to keep tabs on quality control. The engine compartment holds two, nine-liter, four-valve, DOHC, quad-cam, twin-turbocharged Mercury Racing engines with all-aluminum blocks, each one of them good for an electronically-limited 1,550 pound-feet of torque, and either 1,350 horsepower or 1,550 horsepower depending on whether you run regular 91-octane fuel or 116-octane race fuel. So yes, that's 3,100 hp and 3,100 lb-ft at once, if you go all out. Mercury says they're the most powerful powerful emissions-certified gas-powered marine engines you can buy. The engines don't have knock sensors, though, so you have to turn a key to register the kind of fuel you're putting in, and you can switch from one to the other when two 150-gallon tanks are down to 10-percent full.
