2015 Mercedes-Benz S63 AMG Coupe

Conventional wisdom would dictate that adding more power and several key performance enhancements to an already very good car, like the 2015 Mercedes-Benz S550 Coupe, will end up equaling an even better car. In the case of the 2015 Mercedes-Benz S63 AMG Coupe, conventional wisdom sort of applies, but perhaps not as much as we'd have initially guessed. We'll get into the nitty gritty details in just a moment, but here's the most immediate takeaway we had in our minds as we walked away from this super coupe: The S63 AMG is excellent, but so is the slightly more mundane S550 Coupe on which it is based, and which is priced some $41,000 less expensive than its more powerful sibling. Chew on those figures while we examine what differentiates the two S-Class Coupes. Drive Notes As expected, the single greatest highlight of the 2015 S63 Coupe is its engine. As a powerplant, it's a gem. As a hand-built engineering exercise, its 577 horsepower and 664 pound-feet of torque are just as impressive in real life as they sound when recited from stat sheets. Not that the old CL63 AMG was lacking in power, but the new S63 AMG Coupe boasts 41 more horses and 74 more lb-ft than the outgoing engine. The run to 60 miles per hour takes a scant 3.9 seconds, according to M-B, aided in no small part by the car's 4Matic all-wheel-drive system and other assorted electronic brains deciding where, exactly, all those ponies should be sent. The rear-biased system is tuned to send two-thirds of the engine's power to the rear wheels in a bid to make the car feel more like what performance-minded drivers expect. Top speed is electronically limited to 186 miles per hour, which is plenty fast enough, even in the days of 200-plus-mph sedans from M-B's former corporate cousin Dodge. We didn't get anywhere near the car's maximum velocity, but our brief trips into triple-digit territory were quiet, comfortable and completely free of drama. The seven-speed automatic gearbox responds quickly to requests of your right foot, but the steering wheel-mounted paddles don't change gears as quickly as we'd like when in Manual mode. Controlled Efficiency (which we'd call Comfort) maximizes efficiency, keeping the transmission in higher gears and shifting earlier than when in Sport mode, and we didn't find much fault with the computer's shifting algorithms in either setting.

Recharge Wrap-up: Honda FCV Concept comes to Detroit, Toyota seeks young green energy fellows

Honda will bring its FCV Concept to the 2015 North American International Auto Show in Detroit in January. The hydrogen-powered concept made its Japanese debut in November, and will now make its way to North America for the first time. The FCV concept improves upon the design of the FCX Clarity with a more striking appearance and roomier interior. Its smaller powertrain packaging means more space for people, and the FCV Concept seats five passengers. Honda also expects the next-generation fuel-cell car, which is scheduled to go on sale in Japan in March 2016, to cost less and have a range of over 300 miles. Read more in the press release below. The Mercedes-Benz B-Class Electric Drive has been awarded an environmental certificate from the TUV Sud technical inspection authority. The certificate is based not just on the vehicle's operation, but the entire lifecycle of the car, including production and recycling. The B-Class Electric Drive produces 24 percent less CO2 over its lifecycle than the Mercedes-Benz B180 when using the EU electricity mix, and 64 percent less when powered by hydroelectricity. Mercedes credits not just the use of electricity, but also the car's energy management system - such as its radar-based regenerative braking - for its carbon reductions.

One of its stops will have a wireless charging station where the bus will recharge for six to seven minutes before continuing on its route again. The charger is located under the road surface and the bus positions itself above it to charge inductively. About $1.3 million will come from the Swedish Energy Agency to fund the test project, which could save up to 90 percent of fuel costs. If expanded to a fleet of 2,000 buses, it could save up to 13 million gallons of fuel each year. Read more at Green Car Congress, and in the press release below. Sandia National Laboratories and Linde are teaming up to expand hydrogen fueling infrastructure. The two groups have signed an agreement to research and develop new hydrogen stations, as well as ways to make fuel cell vehicles more desirable for consumers. They are looking at ways to incorporate hydrogen into existing fuel stations where possible, and make sure that it is able to be done safely.

Mercedes' Tesla fighter will have 311-mile range

Mercedes-Benz is preparing to take the fight to Tesla, and it'll do it using an EV with up to a 311-mile range, the company's research-and-design boss told German publication Auto Motor und Sport (Google Translate warning). Perhaps more impressive than just the range, though, will be the modular nature of the EV platform, which will allow Stuttgart to easily adapt it to multiple vehicles. "We are working on an intelligent concept for a highly attractive electric vehicle with a range of [228-311 miles]," Mercedes' Thomas Weber said in the interview with Auto Motor und Sport. Weber added that this vehicle is coming "soon," although that word can have multiple meanings in this industry. Mercedes is taking Tesla and the all-electric vehicle increasingly seriously, as Automotive News reports. But while it continues to invest heavily in EVs and hydrogen fuel cells – roughly half of Daimler's $6.4 billion research-and-design budget went into research on low-emissions tech last year – the company is most heavily committed to plug-in hybrids. As previously announced, Stuttgart will field ten new PHVs by 2017, including electrified variants of the C- and S-Class.
