2015 Mercedes-AMG C63 S First Drive [w/video]

As I mashed the throttle heading into the back straight of a nearly three-mile-long race track, I couldn't help but center my mind on two ostensibly disparate subjects: physics and pistons. If the heart of an automobile is its engine, the heart of the engine are its rotating bits – the crankshaft, pistons and the block they're nested inside. It seems fitting, then, that the internals of the twin-turbocharged 4.0-liter V8 typify the brand-new 2015 Mercedes-AMG C63 sedan I found myself piloting in Portugal. Whereas the last C-Class AMG availed itself of a brute of an engine, employing 6.2 liters of displacement to make its 451 horsepower the old fashioned way, the latest AMG's V8 engine has been downsized radically. I had the opportunity earlier in the day to actually hold the pistons of the new 4.0 Biturbo V8 in my hands, alongside those of the outgoing 6.2. The difference in size is staggering, the new lumps looking downright picayune in comparison to the latter. These eight seemingly diminutive pistons turn combustion into crankshaft-spinning power inside a block that is smaller, lighter and more compact than I'd have thought possible, considering the prodigious output the engine spits out. I had gone into this assignment expecting to pen an ode to lost love; a sonnet of sorrow bemoaning the switch from massive cylinders to wheezing power adders. But I was wrong. In fact, the report that follows may indeed read a little like a love song, except it will heap praise not on what used to be, but instead on what is now possible. The new heart of AMG more than makes up for its reduction in size by relying on turbochargers and smart engineering to turn just 4.0 liters into 469 horsepower and 479 pound-feet of torque starting at just 1,750 rpm, or as much as 503 ponies and 516 lb-ft in uprated S guise. Foot to the floor, eyes focused on the turn ahead, a hard right-hander named Primeira that requires hard braking and quick reflexes, I had a fleeting moment of clarity: These are some hard-working pistons. A few days on the street and track in and around Faro, Portugal, has convinced me that the new Mercedes-AMG C63 is a better car in any meaningful measurement than it was before. And I'll go one step further. Not only is this the best C-Class AMG ever, it's also my new favorite in the hotly contested segment that includes such knee-benders as the BMW M3 and M4.

Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.

Britain orders 10,000 ventilators from F1/McLaren/Mercedes/Ford/Rolls-Royce/Airbus

Paramedics and ambulance personnel get instructions from a command unit outside London's ExCel Centre arena, which is being turned into a 4,000 bed temporary hospital called NHS Nightingale to deal with coronavirus patients. The hospital is due to open Monday, March 30. / AP     LONDON — Britain has ordered 10,000 ventilators from a consortium of leading aerospace, engineering and Formula One racing companies which will start production this week in response to an urgent government call for industry to help save lives. The 27-strong team, including Airbus, BAE Systems, Ford and Rolls-Royce, have joined forces to ramp up production of a ventilator made by Smiths Group, which supports those with complications from COVID-19. The consortium, which also includes seven Formula One teams including McLaren and Mercedes, home to World Champion Lewis Hamilton, said they had pulled staff off existing projects to meet the national need. Some 1,228 people have died from coronavirus in the United Kingdom and a senior health official said on Saturday the country would be doing well if it manages to keep the death toll below 20,000. "This consortium brings together some of the most innovative companies in the world," Dick Elsy, the head of the consortium, said in a statement. "I am confident this consortium has the skills and tools to make a difference and save lives." The United Kingdom, which initially only had 5,000 ventilators available in its National Health Service, has been trying to secure additional supplies after realising it needed 30,000 to cope with the peak of the outbreak. Prime Minister Boris Johnson, who is now in isolation in Downing Street after testing positive for coronavirus, made an emergency appeal earlier this month for manufacturers to retool their production lines and start making specialist health equipment including ventilators. Britain now has about 8,000 ventilators, with another 8,000 on order from international manufacturers that are due in coming weeks. Last week it placed an order for a newly-designed model from the vacuum cleaner company Dyson that will need to be approved by the health regulator. Mercedes part of a separate effort, too Separately on Monday a second consortium including Mercedes Formula One and other F1 teams said it had developed in less than a week a new version of a breathing aid that can help coronavirus patients.
