Posted by admin in Concept Car, New Audi R8 E-Tron on March 29, 2011
With the Frankfurt motor show’s press days underway, Audi revealed a technical study that examines what its R8 
sports car might be like if powered by four powerful electric motors. The answer is E-Tron. The four motors fitted under the hood produce a modest 313 horse power but an astronomical 3,319 pound-feet of torque. Isn’t it amazing!
The total torque produced does not come at once. Such a quantity of twisting force usually found in the M47 Patton tank would turn all the tires into rubber vapor at the first throttle. The E-Tron is equipped with an electronic version of torque-vectoring system that is found in some of the Audi cars which are already on the road. This electronic version distributes the required torque to each wheel as needed to maximize traction the cornering ability. As Audi says it takes 4.8 seconds to get to 100 Km/h (62 Mph) from 0. This may not be termed as spectacular when compared with other super-cars. But once the rolling sets to go, the plot quickens – 37 Mph to 75 Mph in just 4.1 seconds, the extra torque stepping into defeat the mountain forces of friction and the resistance by wind.

New Porsche Concept Car

Who would have thought that you could have a mean looking, fast racing, good looking sports car that also has impressive green credentials? Well, that’s exactly what Porsche are proposing with their latest concept car: the Porsche 918 Spyder. Let’s take a closer look.
Unveiled on the eve of the famous Geneva Auto Show, the Stuttgart based company, Porsche, lifted the lid on their new concept car which happens to be a mid engine, two seater sports cars with hybrid and electric drive technology. It certainly looks mean, but what are the stats like? Remarkably impressive when looked at. Nought to Sixty in less than 3.2 seconds with a top speed of 198mph and it happens to be faster than the Carrera GT, as proven by successfully finishing the Nurburgring lap in less than 7 minutes 30 seconds.
So, how can a car have all this power and claim to be green? The 918 Spyder has electric motors at the front and rear axles. The drive to the front wheels is purely electric via a fixed ratio. The liquid cooled lithium ion battery pack sits behind the cockpit and can be ideally charged at home or by brake regeneration.
This sports car is a high revving V-8 related, 3.4 litre racing car. It produces more than 500 brake horse power with engine revs of up to 9200 rpm. Yet, it does an incredible 78mpg, driven the right way, plus the emissions level sit at just 70 grams of CO2 per kilometre.
The chassis is made from CFP (Carbon fiber reinforced plastic), along with the use of a lot of magnesium and aluminium to keep the frame as light as possible. The stylish interior is designed to be driver orientated with touch screens and intuitive controls. Read the rest of this entry »
