New Audi concept of e-Tron is a strong clue yet on the company's intention to build a smaller, lighter sports car known as the R4. New two-seater has the same name as the larger, more powerful concept car revealed at last year's Frankfurt Motor Show and is driven by Autocar last month. However, this car is significantly smaller and, as usual for the Audi concept car with sporting intentions clear, it's rear-wheel drive.
Latest e-Tron, revealed at the Detroit motor show, is also more than one time to display Audi zero-emissions plan: it confirms that the chairman Rupert Stadler Audi has given the green light for new, small, mid-engined sports car.
According to Audi sources, this new concept of e-Tron provides strong evidence for a new production car will be sold as R4. It will share components with the showroom version of the Volkswagen concept BlueSport, and perhaps a new entry-level Porsche roadster, when arriving at a showroom between now and the end of 2013.
Picking up on the styling themes from the first e-Tron, a low slung sports car concept of the traditional silhouette, with a long cap, curved roof line is very short and the back. However, the body is a lot edgier, with fold lines hard, fast surface and the back is sculpted to provide it with a very contemporary look that sets the tone for the next R4.
Elements such as large single-frame grille fins carbonfibre housing for directing air into the front end, and features an enhanced LED headlamp graphics, with a clear set of new cars as the Audi from the front. However, certain features on the back is reminiscent of the Aston Martin models recently - especially the rear lamp graphics.
Organized by a small team working under the British-born manager of Audi's concept car design, Steve Lewis, e-Tron was completed in just four months after the go-ahead from senior management last September.
"We want to encourage electric cars in the sporty without making him look too futuristic," said Lewis. "It's important to give the car a unique technical performance in an effort to convey the message of the electrical package located in the bottom."
At 3930mm long, 1780mm wide and 1220mm high, the concept of shorter, narrower and lower than the original and e-Tron DK today. It rides on a wheelbase, at 2430mm, is 170mm shorter.
At the heart of e-Tron is a new electric powertrain. Using a pair of motors mounted in the rear axle produces 201bhp with a total of £ 1954 with the defeat ft of torque - all delivered to the rear wheels only via a torque-vectoring differential. Official performance figures put the sprint from 0-62mph in 5.9sec and 37-75mph (60-120km / h) in just 5.1sec, but limited top speed of 124mph only to save battery.
Electrical energy is taken from the bank of lithium ion batteries mounted on the back of the villa in the room, the production version of the new R4, will be occupied by the machine. This may include Audi's 335bhp turbocharged 2.5-liter five-cylinder units. Considering a total of 399kg, mid-mounted battery has a capacity of 45kWh, or more than the previous 2.6kWh e-Tron. Fully charged, the concept was placed in the range of 155 miles. Recharging takes 11 hours in a 230V system, but the 400V system this figure dropped to just two hours.
As before R8-based e-Tron, the R4-based version which features an aluminum spaceframe Audi designers have an inherent carbonfibre body panels made of reinforced plastic. This is an exotic combination that helps to provide a car with a curb weight of just 1350kg, although at this stage it is unclear whether the production version of the R4 will follow the same route.
With a lot of weight concentrated in the back, weight distribution is put at 40 percent percent front/60 rear, giving the concept - in the words of the Audi R & D boss Michael Dick - "all the driveability of a go-kart - agile and neutral to the limit ".
