2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

Automakers face reality of EVs' cost — to jobs, and their bottom line

Related: We obsessively covered the Frankfurt Motor Show — here's our complete coverage FRANKFURT, Germany — European car bosses gathering for the Frankfurt auto show are beginning to address the realities of mass vehicle electrification, and its consequences for jobs and profit, their minds focused by government pledges to outlaw the combustion engine. As the latest such announcement by China added momentum to a push for zero-emissions motoring, Daimler, Volkswagen and PSA Group gave details about their electric programs that could give policymakers some pause. Planned electric Mercedes models will initially be just half as profitable as conventional alternatives, Daimler warned — forcing the group to find savings by outsourcing more component manufacturing, which may in turn threaten German jobs. "In-house production is almost irrelevant to the consumer," Daimler boss Dieter Zetsche told reporters on the eve of the Frankfurt Motor Show, in the midst of a German election campaign in which automotive jobs have loomed large. The company set a target of saving 4 billion euros ($4.8 billion) by 2025 to help fund the cost of its electric cars. "Daimler is the first company to state explicitly how much electric vehicles are going to hurt margins," said Bernstein analyst Max Warburton. "It was brave to go first — but of course it won't be the last." Volkswagen, for its part, said it was seeking new global supplier contracts to source 50 billion euros ($60 billion) of electric car content including batteries, which are not yet manufactured competitively in Europe. "A company like Volkswagen must lead, not follow," Chief Executive Matthias Mueller told reporters. VW diesel emissions-cheating exposed by U.S. regulators in 2015 triggered global public outrage, dozens more investigations into test-rigging by the wider industry and a push by some lawmakers to ban diesel and eventually all engines. TIGHTENING NOOSE Tesla shares jumped nearly 6 percent on Monday after a Chinese minister said it was a question of when, not if, Beijing bans fossil-fuel cars, tightening the noose around the combustion engine. France and Britain have promised its outright abolition by 2040. But PSA, the maker of Peugeots and Citroens, said it was concerned about the risks if consumers were left behind in the rush, and a new generation of battery cars does not sell.
