Mercedes-Benz A45 AMG is Affalterbach's first big leap into the little pond

The recent history of AMG is turning out amped-up versions of Mercedes-Benz offerings that would hardly ever be mistaken for their sedate counterparts. Sure, you'd need to pay attention to pick a G-Class from the G63 AMG, but dual side-pipes are a quick giveaway. The Mercedes-Benz A45 AMG is not only a new era in Affalterbach's attention on smaller cars, it is probably also the most subtle transformation we can think of in the line-up.
Low and chunky enough in standard guise to make a sporting impression, the aesthetic makeover is confined to black trim around the lower rim of the hatch, black wheels with red brake calipers and a single, rectangular exhaust tip on either side of the diffuser. It's easier to make a positive ID inside, where the flat-bottomed steering wheel, red seatbelts and red-rimmed details say, "You know what I am..."
If the car is running, though, it won't take but a second. The 2.0-liter turbo spitting 360 horsepower and 332 pound-feet will grumble through a sport exhaust at idle, and bellow through the same on it's way to a 0-60 time of less than 4.5 seconds. And if you need something that looks a little harder - and you want those quad pipes - then the A45 AMG Edition 1 is the treasure you seek. There's a press release below for all the info you'll need until the hot hatch goes on sale in Germany later this year, and photos for the rest of us while we wait to find out if we'll get a chance to buy it.

Test drive the Mercedes SLS AMG Electric Drive with Chris Harris

It's hard to not like the Mercedes-Benz SLS AMG GT. The all-aluminum coupe is fitted with a wonderful naturally aspirated 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque. Not only does the burly combustion engine launch the two-seater to 60 miles per hour in less than four seconds, but it does so with one of the world's greatest exhaust soundtracks as it roars, burbles and cackles down the road.
But what happens when Mercedes-Benz takes away the V8 and its accompanying fire-burning song? Stripped of one of its most appealing assets, does the SLS lose its soul?
Chris Harris recently had the opportunity to take the Mercedes-Benz SLS AMG Electric Drive for a track spin in Europe. Sans gasoline, but with four electric motors providing a combined 740 horsepower (737 pound-feet of torque), all-electric all-wheel drive coupe uses sophisticated torque vectoring and a multi-mode operating system to put oversteer - drifting! - back into the equation. Fun? You bet. See for yourself, below.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
