Mercedes-AMG planning more hardcore A45 hot hatch

The launch of the A45 AMG marked Mercedes-Benz's first real assault on the premium hot hatch segment. And with 355 horsepower from a 2.0-liter turbo four, it is indeed hot. But the latest word has it that Mercedes-AMG is planning an even hotter version. Speaking with Auto Express at the LA Auto Show last week, AMG boss Tobias Moers indicated that his department was toying with the idea of a more hardcore version of the A45. In what Moers referred to as a "street fighter," the A45's engine would be tuned to produce even more power, the cabin stripped out and the rolling stock, brakes and aero upgraded for more serious performance. Think of it, then, as something of a Black Series approach, only it's not expected to carry that name, which has historically been reserved specifically for two-door models. Given AMG's current list of priorities and limited manpower, though, Moers suggests it will be several years – likely towards the end of the model's life cycle – before it may prepare such a model, following a similar formula to the Mini JCW GP and Renaultsport Megane R26.R. Here's hoping an American version based on the CLA could also be in the cards.

Recharge Wrap-up: Daimler spending big for fuel cells, Ford Go!Drive experiment advances

Ford's Go!Drive experiment is entering its beta phase in London. The project, which is one of the automaker's global smart mobility experiments, uses a mobile app for on-demand carsharing of Ford Focus Electric and Ford Fiesta vehicles. The beta phase involves increasing the number of available vehicles from 20 to 50, and collecting new data from users. The program offers one-way rentals and guaranteed parking, with no membership fees and a cost of 26 cents per minute. Ford hopes to get 2,000 drivers involved in the program.

The company expects cost savings "in the range of hundreds of millions of euros until 2020," while maintaining its workforce of 18,700 employees and adding 150 vocational training positions. The upgrades will allow the plant to become a center for building more efficient engines, hybrid powertrains and fuel cell systems. "Alternative drive systems are an important element of our future mobility," says Mercedes-Benz's Markus Schafer. "Their share of automotive production is set to steadily rise over the next few years, complementing our highly efficient engines within the portfolio. This is what we have laid the groundwork for today." Read more at Reuters, or in the press release below. The Department of Energy is providing $20 million in funding for the development of more efficient high speed industrial motors and drives. Ditching old motors and gearboxes for ones that use integrated power electronics could help decrease the energy consumption of the industrial sector, which currently uses more than 25 percent of the electricity generated in the US. The projects being funded will reduce losses and decrease the size of drive systems used in industries like petroleum refining and natural gas, which could affect the lifecycle efficiency of transportation fuels.

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.
