2016 Mercedes-Benz C450 AMG Sport is not too hot, not too cold

Mercedes-Benz is moving to a new system for performance models, launching its AMG Sport line that will slot above the standard cars, but below the full-fledged Mercedes-AMG offerings. The perfect example of how this all looks can be seen with the C-Class – we've already driven (and enjoyed) the standard C300 and C400 offerings, and we're absolutely geeked to test the Mercedes-AMG C63. Slotting in the middle, though, is this new C450 AMG Sport, which makes its debut at the Detroit Auto Show this week. Power comes from the twin-turbocharged 3.0-liter V6 found in the C400, but output is increased to 362 horsepower and 384 pound-feet of torque – up from 329 and 354, respectively. That's all shuffled through the company's 7G-Tronic seven-speed automatic transmission, and sent to the road via 4Matic all-wheel drive. Hitting 60 miles per hour is said to take just 4.9 seconds, en route to a 155-mph top end. There's an AMG adaptive sport suspension with adjustable dampers (from the C63), and the interior and exterior aesthetics have been pumped up for a more sporting appearance. It all seems like a good fit, and we think it'll slot nicely in the middle of the already good C-Class range. Check out our fresh batch of lives images of the C450 above.

Genesis G70 vs sport sedan rivals: How it compares on paper

We got our first look at the Genesis G70 sport sedan today. We think it looks good, with enough ties to its fellow Genesises (Geneses?) to further establish the brand and just enough distinction to help it stand out from the crowd. But ah yes, the crowd. Although Genesis didn't release the G70's full spec sheet, it revealed just enough for us to start sizing it up to its future competition. There are certainly others with which to compare (Lexus IS, Cadillac ATS, Alfa Romeo Giulia, Jaguar XE just to name a few), but we decided to take a look at the best sellers and most competitive luxury sport sedans. (And hey, if you like this, we can always do a follow up) So, here we have the Genesis G70 vs BMW 3 Series vs Audi A4 / S4 vs Mercedes-Benz C-Class vs Infiniti Q50. Nothing like a good chart to dig your teeth into on a Friday. Note that we only compared those models that line up with the G70. So, we left out the BMW 320i and Audi A4 Ultra entry level models as well as the Q50 3.0t mid-grade model that's considerably cheaper than the German performance upgrade models we listed. All 0-60 figures are rough estimates based on several sources, models/drivetrains and OEM figures.

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.
