Super Green: The New Wave Of Environmentally Conscious Exotic Supercars

It's not that easy being green, least of all if you're a builder of exotic, high performance supercars or uberluxury sedans. Recently however, there has been a move towards improving fuel economy and reducing emissions by many of the world's biggest and most well known luxury and performance brands.

Take Ferrari's stop-start equipped California HELE or Mercedes-Benz's SLS AMG E-Cell concept, for instance. And there's more on the horizon, including the plug-in hybrid 918 Spyder from Porsche and BMW's Vision EfficientDynamics, the latter of which allegedly will offer M3 performance with a CO2 emissions rating of just 99 grams per kilometer.

And it's not just these four who are in it for the environmental crowd cred: other makers including Lotus, Audi, Lamborghini, Jaguar and Bentley are also looking to green up their model ranges.

This comes as no surprise to Christoph Stuermer, an analyst at IHS Automotive in Frankfurt:

"These upper-end, high-performance cars have always been examples of the best car technology out here, and being green is now part of being technologically advanced They have to come up with something so as not to be seen as technical dinosaurs."

Enrico Galliera, the commercial and marketing senior VP at Ferrari, agrees that it's definitely something that the company's customers are all for:

"When you consider buying a Ferrari, you're considering it for the performance. At the same time, when we approached customers and said, 'Here's a way you can still have that and be greener,' the reaction was extremely positive."

So there you have it. Now you can have your cake and eat it too, though you'll have to pay for the cake part first. And with prices around €180,000 (US$252,376) for the California HELE and an expected €500,000 (US$682,260) for the 918 Spyder that is one expensive, green frosted cake.

PS: Metaphors aren't my strong point...

Volkswagen to offer Media Test Drives of All-Electric Golf Blue-e-motion at LA Auto Show

At next week's Los Angeles Auto Show, Volkswagen will offer U.S. media representatives the chance to drive the all-electric Golf blue-e-motion. Based on the five-door version of the German hatch, the Golf blue-e-motion has a 115 hp (85 kW) electric motor, powered by a 26.5 kilowatt-hour lithium-ion battery, and a driving range of up to 150 km (93 miles).

A production version is scheduled for launch in 2013.

The car's 30 battery modules (consisting of 180 lithium cells) are installed in the floor of the boot, under the rear seats and in the center tunnel of the underbody. This way much of the boot space was retained, as useable cargo capacity amounts to 275 liters. However, the weight of the battery pack is another story. It adds a whopping 315 kg (695 lbs) to the car's weight, seemingly crippling it.

Luckily, as with any electric motor, the Golf blue-e-motion has plenty of torque, more precisely 270 Nm (199 lb-ft), so it's capable of completing the 0-100 km/h (62 mph) sprint in 11.8 seconds, while top speed is limited to 135 km/h (84 mph). Granted, that's not a new world record, but, still, it's enough for your everyday commuter's needs.

To extend the range as further as possible, engineers made the car more aerodynamic, reducing the drag coefficient to 0.295. Furthermore, the blue-e-motion can "sail". This occurs when the driver releases the gas pedal. At that moment the torque drops to zero, helping the car coast with the least possible drag, while recovering kinetically generated energy and storing it in the battery pack.

Three driving profiles are available in order to make the blue-e-motion more suited to specific needs. In "Comfort+" mode, full power is used, so the car can reach its top speed. When "Normal" is activated, output drops to 87 hp (65 kW), as does the top speed to 115 km/h (72 mph). In "Range+", the focus is on, well, maximum driving range, so power is limited to 67 hp (50 kW). In this mode, the car's top speed is further reduced (105 km/h or 65 mph) and the air conditioning system is also completely deactivated in order to save battery power.

Compared to a standard Golf, the blue-e-motion has a slightly tweaked exterior with a wider, double-bar grille, LED daytime running lights, black window trim and a roof spoiler.

Inside, it's business as usual, with the usual amenities seen such as eight-way adjustable seats, foldable rear bench and brushed metallic trim inserts.
