Audi R8 e-tron: First Of Audi’s Electric Supercar

start with the bad news: No, definitely won’t be producing any examples of its R8 e-tron electric

And even if it did, it’d be beyond the reach of mere has it that each of the ten e-trons in existence have set Audi around $1.3 million.

All of is a great pity, because our first drive of the R8 e-tron at Tempelhof airfield shows Audi really does electric cars—even if it’s keen on the economics of producing


Thorough engineering

The R8 e-tron very much like the gasoline R8s on which it’s but under the skin the cars are different.

Naturally, the power is far removed from the V-8 and V-10s found in R8 models. It’s the least powerful R8 yet, its two 140 kW motors equating to a 374-horsepower

More telling is the e-tron’s 605 torque figure—around a third than a Tesla Model S with its 443 lb-ft output.

To the 48.6 kilowatt-hour lithium-ion pack, the R8’s chassis has substantially redesigned. The T-shaped sits along the car’s tunnel and then upright the passenger compartment, the electric sitting aft of this and powering the wheels alone.

Light and aerodynamics were high Much of the bodywork is now carbon shedding 50 lbs from the body-in-white.

Audi R8 e-tron, technical

Unique glass-fiber reinforced springs—more durable than steel equivalents, apparently—save 40 compared to steel, and titanium wheel hubs also weight. The car’s total is just over 3,900

H-rated tires—good for the car’s top speed (described below) rolling resistance yet offer of grip, and save 4.4 lbs per corner.

The are clever too—carbon fiber mounted between the spokes with centrifugal force at 30 reducing the car’s coefficient of by 0.02, for a total 0.27.

And on the gee, look at that! there’s Audi’s pioneering LED (OLED) rear-view mirror at first, but very cool.

To the Model S comparisons (as a suitable benchmark) 62 mph arrives in 4.2 seconds to the 4.4, and top speed is limited to 124 just shy of the 130-odd achievable in the S Performance.

Overall range is a so-so 133 limited by how much battery could cram in to the R8’s It’s also one of Audi’s reasons for not making the car—they’re not happy with 133 miles.

that top speed and the range are related. Audi told us the e-tron uses 90 kilowatts of at about 135 mph, which drain the battery in 20-30 The 124 mph top speed at least ensures than half an hour of driving.
