Audi Sport Lowballs Performance Numbers, According to Tech Boss

You may remember late last year watching Motor Trend’s “World’s Greatest Drag Race 6!” and seeing the Audi R8 win with a 10.6 second (Dom Toretto approved) quarter mile time and a 0-60 time of just 2.6 seconds. And that last number may have caught your attention because Audi, who made the car, say that it does the 0-60 run in 3.2 seconds.

Why the disparity? Well, apart from human error (which any tester worth their salt will run multiple tests to try to avoid) it could just be that Audi is lowballing.

Okay, not lowballing, quite, but according to Audi Sport’s head of technical development, Stephan Reil, the brand deliberately quotes conservative numbers to keep buyers from being disappointed and journalists from getting too snarky.

“And the reason we are conservative with these numbers is simple,” said Reil, speaking to Australia’s CarAdvice. “I simply don’t want to hear, when you guys write ‘well, they claim 3.9, but we got 4.0’.”

According to Reil, the practice has been going on since he started in his position nearly 20 years ago and goes on to this day with the RS5.

“So, if we say 3.9 seconds, you will measure, maybe, 3.7 if the conditions are fine, probably 3.8, but even under the worst conditions, you’ll do it in 3.9 seconds. But you will not find a 4.0,” said Reil.

Reil also revealed that Audi kept the RS5 producing just 450 hp, but upped the torque to 442 lb-ft for the customer’s benefit.

“Let me put it this way: The customer buys horsepower, but what he drives is torque,” he said. “And what’s important is how the engine delivers that torque. Does it come early, does it come with some lag, or does it come the moment you give it some throttle?”

So Audi focused on giving the new RS5 more torque (100 lb-ft more than the outgoing model) instead of more hp. And with the torque peaking between 1,900 and 5,000 rpm, it’s available from way down low.

That’s thanks to the turbochargers’ location: between the cylinder banks. With less piping and better flow, the driver gets better throttle response and minimal lag. Reil admits, though, that there’s still room for improvement.

“What we have done with the new RS5 is the best we can do right at this time, but of course technology gets old quickly, so we will be able to do better once new systems arrive, such as 48 Volt systems, which we will be able to fit into cars like this one – otherwise it’s more suited to SUVs like our SQ7 at the moment.”

Watch: The Stig Drives (nearly) Seven Generations of Golf GTI

With Volkswagen announcing “major” updates to the Golf, it seems an appropriate time to look back on what we’ve had so far. And who better to guide us through the rich history of the most popular European car ever made than Ben Collins, the former Stig? Some say he’s never met a GTI he doesn’t love, and that he can’t grow any of his own facial hair. All we know is … Ben Collins is actually a pretty solid presenter. Working his way through seven generations of the GTI (skipping over the Mk6) Collins tells us a little bit about each one and matches each mark to its corresponding facial hair craze. The Mk1 GTI for instance, is light and quick, but can lose traction under hard acceleration (in heavy rain). Despite that, Collins calls the Mk1 a “pure gem.” The Mk4, meanwhile, is a powerful return to form after the perhaps too sensible Mk3. Collins ends in the only way he could, with the Mk7, which accelerates faster than a Lamborghini Countach and is all kinds of wonderful. Watch, ...

Watch: The Story of the Ads that Made VW Big in America

The ads for the original Beetle are almost as famous and well-loved as the Beetle itself. Looking back now it’s easy to forget, though, just how easily things could have wrong. A new short from Dial M Films tracks the history of those early Volkswagen ads that sold America on the people’s car. The story, of course, begins with the visionary agency that made the ads: Doyle Dane Bernach (DDB). As a popular agency for Jewish products, no agency was more aware of the implications of Volkswagen, and no one, it seems, was more skeptical of the brand than DDB. “Remember Those Great Volkswagen Ads?” from Dial M Films on Vimeo . William Bernbach, though, was adament that the firm take the client, probably as a way of attracting other lucrative automotive clients. Saddled with a client that he didn’t want, art director Helmut Krone says in the film that he originally came up with ads that were all wrong. Krone tried to do what other manufacturers did and was intent on selling the Beetle ...

Watch: The Zerouno Cruis’n USA

ItalDesign is drumming up excitement for its new supercar based around the same 5.2-liter Audi V10 that powers the R8. Naturally, it hit the road for a cruise around California last week to celebrate Monterey Car Week. There isn’t much in the way of V10 noise—which is a real shame given the sound it makes—but you do at least get a good look at the car inside and out in this video. With a body made entirely of carbon fiber and designed to be as aerodynamic and light as possible, ItalDesign figures that it will be good for a 0-60 time of just 3.2 seconds. “We put it our best skills into the production of the first car,” said Massimo Bovi, head of pre-series production, when the Zerouno was first unveiled in Geneva earlier this year. “Using some of the finest productions methods and engaging our high-skilled workers.” The car features clever aero tricks gleaned from single-seat racing, like a y-duct up front to improve downforce and turn-in. Available in a number of trim levels, the...
