Audi R8 E-Tron

Remember that kid in your elementary class who lived on the edge of town and his cool dad let him drive the old governor-free electric golf cart? Today that cool dad is Audi, that golf cart is the Audi R8 E-tron, and that kid is me.
Banish the memory of the screamin’ red Audi E-Tron that stormed the auto show circuit in 2009. That car is pretty (and looks prettier with R8 V10 wheels) and exists as a drivable prototype, but today we’re talking about the R8 E-tron, a rolling test bed used to beat the snot out of Audi’s prototype electric powertrain. Behind the scenes Audi’s busily working away on a plan to put an electric R8 into production sometime in 2012. Within 20 years it’s planning hybridization or electrification to touch most if its lineup in some way. This is not the end of the world, just the beginning of a brave new one.
From the outside it may look like an R8 tarted-up with electric yellow whatsits and a new engine cover, but underneath it’s all techno-wizardry and electronic nerd stuff. Rather than a thumping V8 or Lamborghini-derived V10, this one packs not one, not two, but four asynchronous electric motors driving each of the wheels independently, together they weigh a sprightly 375 lbs and develop 442 lb-ft of torque with 308 HP. If not for that 53 kWh, 1100 lb lithium ion battery taking up the engine bay we’d be talking some serious get up and go, but alas these are the sacrifices necessary for a 155 mile range.


One or two very powerful motors might seem the ticket but with four independent motors you can make the car turn on a dime, literally. Imagine complete freedom to power any wheel at any time independent from the others. Torque vectoring, yaw control, stability control all take a giant leap forward. Add this bit of vocabulary to your memory banks and store it away: “Selective Acceleration.” Rather than braking an individual wheel to provide stability control, certain wheels can be accelerated to provide both a stable vehicle and even faster corners — tasty. Heck, if they wanted, engineers could scrub those big Pirellis down to nothing in a jiffy by turning the car around in place like a tank. Four motors takes “Quattro” to a whole new level. It’s still a long way between here and there, though.

Let’s go back to that golf cart reference from earlier. It’s pertinent because the R8 E-Tron isn’t nearly a finished car yet, it feels exactly like a sleeker, burlier version of the ubiquitous, white, squirrel-chasers. That’s fine, this is just a mule after all. Beneath the skin, mysterious whirs and clicks are present even standing still, the center console, having no need for crazy stuff like a parking brake, has been remolded. The center LCD screen displays vehicle system statuses and rather than a tach you get a “% Power” meter where doing your best to peg the top end is the hoon’s objective. The seats have been tossed for racing buckets. It’s purpose built, stripped down and techy with little mind paid to the fetishized and bloated ideal of what makes a supercar these days. It’s cool.
Close the door, buckle your seat belt, and whoo hoo! Ignition button. “Click”… nothing. Maybe the biggest let down of an electric supercar is the absence of the dramatic engine firing. It’s fine in any of the mundane human-moving hybrid appliances out there, not even missed, really, but on a supercar it kinda stings the soul a little bit. Turning a key or flipping a momentary switch used to unleash the wrath of hell, now it just turns on the power electronics and initializes software.

Lamenting the idiosyncrasies of the past is for future-fearing curmudgeons though. Mash the pedal and crush your spleen, you’ll get over the lack of an exhaust note. 0-62 mph comes in 4.8 seconds on the way to a top speed of 155 mph, riding a glorious wave of torque all the way. It’s like being kicked out of a plane with the sound of an RC car replacing the wind rushing by your face. Throwing the car into a corner delivers the familiar razor sharpness from the R8 4.2 — a precision instrument designed for trained professionals and delightfully harmful in the hands of the foolhardy. The steering is heavy, overly heavy, as if they’d forgotten to turn on the electronic power assist, but that just adds to the golf kart feel. It’s an R8 in the raw, only with a side of silence and electric motor whir.
But is it a supercar? It’s a little bit herky-jerky, the connection between pedal-to-the-metal and crushed spleen is occasionally delayed or delivered stepwise. The car shudders once in a while. You can hear the wheel bearings turning. There are no heated seats. There are squeaks in the cabin. There’s no suede headliner. The center console isn’t leather wrapped. The cupholders are too shallow. It doesn’t even have satellite radio.
Just kidding. It’s the funnest golf cart I’ve ever driven. Between now and 2012 the drivetrain and power delivery software will be whittled to perfection, a new chassis will arrive designed with the electron-motivation in mind and battery tech will advance even further. When it’s finished, the production R8 E-tron will undoubtedly be the must-have stupid car on every wealthy golfers list. Even Elin Nordigren couldn’t chase this one down.

Second, if they get this thing sorted out, and can off a decent range and R8-deserving performance I could get on board with the electrification of a supercar. I wonder why, with all the TDI-ification of the model lineup at the Four Rings, they don't do a diesel-electric hybrid? Ditch some of the batteries and put in a series diesel as a "range extender"? It seems to me that a pure electric is still too much of a tradeoff due to current battery technology. Some day we may have inexpensive supercapacitors to give us 300 mile range in a weight-efficient package, but not yet. Until then, I take a dim (haha, get it?) and cynical view to pure electrics, particularly in a performance application like this or the Tesla.
First, maybe this time I'll get him on his own and politely ask him how in the heck I pronounce his surname.
Second, I totally agree. Electrification seems to lend itself to supercars, where practicality isn't job #1 and power is everything. And as long as there's enough range for a days fun on the road, back-road blasting rather than crossing continents, it could work quite well.
But it strikes me that hybrids have skipped an evolutionary step by not taking the diesel electric route. A diesel running at maximum torque can be pretty damn economical, even more so if it's only being used to excite a generator. For a family car application, hub motors driven by a diesel generator always perfect sense to me, and are easy to package with no mechanical linkages and no need for huge battery packs.
Lots of automakers have toyed with the diesel/hybrid idea but it's the costs that have kept it out of production so far. Perhaps it would make more sense in a supercar where cost is less of an issue, but then why not go all the way and use turbines? They're very efficient at steady speeds and can use just about any combustible fuel.
Yep. Small, light turbines have been used as Auxilliary Power Units on aircraft for decades.
Hey, Maybe Mazda should experiment with a rotary hybrid?
Jaaaaaag has that very idea in their C-X75 concept, with not one but two little diesel-burning turbines.
Exactly, and a diesel motor running at a fixed speed is darn efficient.
Oh, and it's pronounced "Whoa-di-la", or, as I like to say, "Who-dya-la-la".
Cheers mate, could have been embarassing at the wedding….
I prefer "Wojzilla". Or, because he's somehow related to the previous Pope of the same last name, "Voy-dee-wah". It's not how HE pronounces it, but what does he know?

It's really interesting watching contemporary automakers struggle with century-old technology that hasn't progressed at all when compared with just about everything else that got invented a century ago (for example: the kinematiscope). I have zero problem with electric cars of any sort, be they the Mitsubishi MIEV or this tasty paean to criminally overpaid investment bankers, as long as they represent a real leap forward in efficiency.
Great read; thanks Ben!
This makes sense. Herr Doktor Porsche helped create the 1st cars to wear the 4 rings, and he created one of the first electric cars. It only took Audi seven or eight decades to put zwei und zwei zusammen.
Oh, yeah……hello, Ben.
HOLY CRAP IT'S BEN WOJDYLA!
Great write up Ben. I like that you took the mule at face value and projected where this technology could take us. That and you used a lot of 5-6 syllable words.
The idea of controlling torque at all 4 wheels completely independently of each other has my head approaching critical internal pressures…explosion might be imminent.
Seriously, that could be…huge…
No kidding! When I read that I immediately imagined myself on a track with lots of grass run-off and the torque set to full drifto-mode, or doing a huge front-wheels burnout just to mess with people's heads.
huge *4-wheel* burnouts. With selective torque and what not, you could put the aft wheels in reverse, forward wheels in forward, and mash the go pedal with amazing results!
how about front wheels in reverse, ass end in fwd, and see what kind of joyous, smoky, uncontrolled hoonage ensues?
You know, if you take this to the same level as they take fighter planes, you get unstable steering geometry with an electric nanny keeping things on the straight and narrow, resulting in slalom abilities that put your neck at risk.
Or you could just get out of parking spaces by turning in place like a skid-steer!
Did I mention HOLY CRAP IT'S BEN WOJDYLA!

Imagine a Wrangler ElecriXtreme in rockville!
the correct term, I believe is "head assplode"
"Rather than braking an individual wheel to provide stability control, certain wheels can be accelerated to provide both a stable vehicle and even faster corners — tasty."
I missed you Ben.
I have a feeling that mid year 2012 were going to see alot of blogposts about these beasts being involved in un-Hoonworthy accidents.
Oh yeah….HOLY CRAP IT'S BEN WOJDYLA!!!
And for once, this olelongrooffa has the right to comment on one of his articles!
Ben! Ben! Hey Ben! Hi.
Selective acceleration sounds like the most awesome use of an electric drivetrain yet.
Interesting bit of kit. Four motors introduces a new level of hoon-smoke generation. However, electric and VAG bring to mind dark times of Lucas. Or have the Germans gotten better with their electron management?
HOLY CRAP IT'S BEN WOJDYLA!!One!!exclamationpoint
I trust Germans with electric, but not electronic stuff.
Electric = analog and switches and stuff.
Electronic = chips and digital logic.
HOLY CRAP BEN WOJDYLA IS ON HOONIVERSE!!!!!!
Great write-up, Ben…! I look forward to many more…
A breadboarded arc-welder with wheels. Snort. I want the beast and I want it programmed to do burnouts with the front and rear wheel pairs turning in opposite directions. Muh HHaaa! Mess with their minds!
And, hey, it's BEN!
I don't care about electric cars so much; I really just wanted to say
HOLY CRAP BEN IS ON HOONIVERSE
Which, by the way, is the perfect site to give us an update on the Conti.
Seriously, really good to see you here!
I will not give into the "HOLY CRAP BEN IS ON HOONIVERSE" meme. Ho, wait, never mind…
Brian does bring up a good point: an update on the Continental would be well received in these parts.
An update to the Conti (among other things) is forthcoming. Almost everything is metalwork and bondo right now.
As someone who drives an electric car daily, I can assure you that maximum torque at zero RPM never gets old. Now add all wheel drive and torque vectoring voodoo magic, i would live in it!
Oh hell, why not?
HOLY CRAP BEN WOJDYLA IS ON HOONIVERSE!
And Murilee is now on TTAC.
Super psyched for MM on TTAC, too.
This is a dream right….
Nope it's real, phew
Oh yeah, I read about that the other day. Best move TTAC has made in a long time. It will be interesting to see how Jalop TTAC gets.
Great review Ben. And good to see you on here. You deserve to write wherever you damn well please. You've earned that much.
Ladies and gentlemen, meet your new Hooniverse Detroit Editor and Test Drive Specialist.
Seriously, is there anyone you'd rather have in the job?
HOLY CRAP BEN WOJDYLA TOTALLY KICKED A LEMUR'S ASS!"
Sister site meme incest.
Little known fact, Ben is actually nuclear-powered.
Murilee, on the other hand, is powered by diesel fuel and Pabst Blue Ribbon. That saucy minx.
I'm still laughing about this one. Crossover meme FTW!
(And by crossover, I don't mean a fat wagon.)
I hope we haven't heard the last of Ben, although I'd totally understand if he decided to change gears and return to honest employment.
HOLY CRAP SISTER SITE MEME INCEST!!
Oh, and holy crap Ben is on Hooniverse!!
Ben who? Are you the infamous Ben Wabbles? I keed, I keed.
HOLY CRAP BEN IS ON HOONIVERSE!!
Finally an electric I want to drive.
Thanks everyone, I appreciate your enthusiasm. El Hoon may not pay the bills, but it soothes the soul.
We offered you four whole dollars a month! How much more do you WANT?
Can you withhold payment until he submits a write up on the progress of the Lincoln? Us Hoons are chomping at the bit to know where it is at!
Offer him prizes. That always works.
How about in Trident Layers?
