Mercedes-Benz C-Class Coupe looks just as banging as big brother

When Mercedes-Benz redesigned the C-Class, the new sedan was crafted as a sort of baby S-Class, both inside and out. So is it really any surprise that with the 2017 C-Class Coupe, MB has once again looked to its flagship model for inspiration? The new C Coupe is, for all intents and purposes, a scaled-down S-Class Coupe, featuring many of the same styling cues that make that big two-door such a stunner. The pert tail is set off by the same kind of duck-bill spoiler integrated into the rear decklid and horizontal taillights. A strong shoulder line emphasizes the aggressive slope of the roof and the high beltline, which if anything is more aggressive than what Mercedes penned for the S-Class Coupe. Up front, a strong grille is flanked by scale model's of the S Coupe's headlights, complete with LED lighting accents. It's a similar story in the cabin, where Mercedes scaled things down but really didn't skimp on style or materials. Expect the C Coupe's mechanicals to mirror those of its four-door counterpart. The C300, the only version of the new two-door to be announced so far, will use the same 241-horsepower, 273-pound-foot, 2.0-liter, turbocharged four-cylinder as the C300 sedan. We'd expect the rest of the engine range to get fleshed out over time, with the more potent C400, C450 AMG Sport, and C63 AMG coming online. While not specified, a seven-speed automatic should be on hand to funnel power to either the back wheels or to a 4Matic all-wheel-drive system, here in the C300. As for optional extras, Mercedes specifically mentions an Airmatic suspension, a vast suite of safety systems, and a 360-degree camera, to name just a few. As with the engine lineup, expect the options sheet to mimic the C-Class Sedan. You can read more about the new C-Class Coupe in the attached press release. We've also embedded a hefty gallery of images at the top of the page. The new C Coupe will make its auto show debut at next month's Frankfurt Motor Show, and will hit dealers in the US next this spring.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.
