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.

Mercedes pays tribute to 1955 Mille Miglia with special-edition SL

The Mercedes-Benz SL is one of the longest-running nameplates in the business, and its history has been marked with numerous achievements. But few were as impressive as the 1955 running of the Mille Miglia, and Mercedes pays tribute to that race and the results it achieved there with this latest special-edition roadster. Called the SL Special Edition Mille Miglia 417, this roadster starts with the eight-cylinder SL550 with dynamic stability management and adaptive damping and adds on several highlights. Red trim adorns the front spoiler, the stripe across the matte carbon rear spoiler, the brake calipers and the rims of the black AMG Performance wheels. The red pieces accent the matte black paint, while the interior features AMG Line sports seats with carbon-finish leather and red trim, along with a red and black nappa leather steering wheel and carbon trim. The SL arrives 60 years after the Mille Miglia in which a 300 SL driven by American gentleman racer John Fitch - bearing the number 417 and starting at 4:17 a.m. - led a 1-2-3 class finish, landing fifth overall and leaving many purpose-built racers in the dust. The special edition is confirmed for the US, arriving this fall with pricing to be announced closer to launch. SPECIAL EDITION SL "MILLE MIGLIA 417" Exclusive SL passion February 17, 2015 - Stuttgart -- Mercedes-Benz celebrates the 60th anniversary of a memorable motor racing success with an extraordinary special model of the SL Roadster. Its name commemorates the unexpected victory of a 300 SL in the production sports cars class at the 1955 "Mille Miglia", one of the world's most challenging long-distance races. What's more: the SL Special Edition "Mille Miglia 417" provides a special experience of the unique symbiosis of maximum comfort and motor racing spirit that traditionally characterizes every SL. The Special Edition adds a distinctive note, among other things, with red exterior highlights and fine materials in the exclusively appointed interior. The Mercedes-Benz SL Roadster is more than an icon. Passion shapes its character and its charisma – in the past and today. Legendary vehicles and their stories dominate the model history. One of them is told by the SL that started the famous "Mille Miglia" in 1955 with race number 417 at 4:17 am. After 11 hours, 29 minutes and 21 seconds it had completed the race distance of 1597 kilometres on public roads from Brescia to Rome and back.

Mercedes C350e PHEV will start at 51,000 euros

Mercedes-Benz will start selling its C350 Plug-In Hybrid in Europe next month, for a somewhat reasonable price. The Daimler division has announced the sedan will cost about 51,000 euros ($58,000 US). Which isn't insanely expensive by Benz standards. Mercedes first showed off the model stateside at the North American International Auto Show in Detroit last month, and the specs were pretty impressive. The car delivers a combined 275 horsepower and 443 pound-feet of torque from its gas-powered engine and electric motor. The C350 PHEV also offers a 112 miles per gallon equivalent fuel efficiency rating (using the more lenient European driving cycle) alongside a 0-60 mile per hour acceleration time of less than six seconds. And the car can go as far as 20 miles on electricity while reaching a top speed of 130 miles per hour. Both lead-footers and tree-huggers can rejoice at that. Americans won't be that far behind their European brethren, as the model will go on sale as a 2016 model-year version in the US this fall. In the meantime, for some more information on a sedan that we think qualifies as a bit of guilt-free fun, take a look at Mercedes's press release below. Sales release for the C 350 e: Future inside Stuttgart, Feb 02, 2015 Stuttgart – As a plug-in hybrid, the new Mercedes-Benz C 350 e combines an extraordinary level of efficiency, dynamism and comfort. In both its Saloon and its Estate guise, the performance of a sports car makes it a convincing proposition, especially combined with certified consumption figures of just 2.1 litres of fuel per 100 kilometres and a range of up to 31 kilometres in all-electric mode. Both the Saloon and the Estate model are equipped with air suspension and a pre-entry climate control system as standard, delivering a unique level of driving and climate comfort. The C 350 e is available to order now from 50,961.75 euros for the Saloon and 52,627.75 euros for the Estate (prices include VAT). Both vehicles will be at dealerships from March 2015. As a plug-in hybrid, the C 350 e combines a combustion engine with an electric drive system and a high-voltage lithium-ion battery with a capacity of 6.38 kWh, which can be charged from an external power source. Thanks to an intelligent on-board charging system, this takes approximately one hour and 30 minutes at a wallbox. A charging time of around two hours is achievable via a socket.
