The Fastest Audi A4 in the World


On October 22, 2006 the Hohenester HS650 Nardo circled the high-speed test track at a speed of 213.7 mph (343.9 km/h). On December 1, 2006 the world's fastest Audi A4, equipped with an H&R coil-over sport suspension, celebrates its public world debut on the H&R stand at the Essen Motor Show 2006.

Tuning specialist Alfons Hohenester installed a twin-turbo V6 engine with an increased displacement of 3 liters under the hood of a visually discretely modified Audi A4 sedan. The engine was tuned by the company-own engine shop and produces a maximum power output of 650 bhp at 7,300 rpm and a peak torque of 531 lb-ft at 3,800 rpm.

That makes the Hohenester HS650 Nardo a force to be reckoned with not only when it comes to top speed: With sprint times of 3.4 seconds from rest to 62 mph, 10.3 seconds to 124 mph and 29.8 seconds to the 186 mph barrier the 4x4 delivers performance figures that only a very select few super sports cars can match. And it does so while meeting stringent Euro 4 emission limits.

To make safe use of this performance potential Alfons Hohenester relies on a height-adjustable H&R coil-over suspension: "The uneven and banked track in Nardo places extreme demands on the suspension at speeds above 180 mph. Together with our development partner H&R we found a great setup that made our HS650 Nardo absolutely safe and easy to drive. It was this combination of professionally tuned suspension, extremely powerful engine and modified aerodynamics that made our record possible."

Why did they get a midget to drive it?!

thats an amazing car and its soo fast

Why did they block the Single Frame grille and the other intakes? That's just plain Veyron-esque cheating if that's supposed to make it go faster. Wouldn't the lack of intake air make it slower, despite improved aerodynamics?

Why didn't they plan this on a RS4 ?
It might looked better than this A4 .
I'm impressed with it's crazy stats though .

It doesn't seem a 650bhp car. Nor spoilers neither aerodynamics gadgets

^ A spoiler would kill the top speed. It has a lot of aerodynamic gades though. The intakes and the grill is covered. The wing mirrors has been replaced with DTM mirrors.
There's also some aero device placed in front of the front wheel well. I haven't come up with a justification for that thing yet, so don't shoot me if I'm wrong, but I assume it helps improving wheel well extraction.

Haha! He's tiny isn't he!

As for the car, it's er....different? Just looks like a riced up A4. Back lights are not nice, nor are the stickers. All this crap on the sides just nullifies all the performance of it.

Stock one for me.

its a beast and soo fast.

Audi looks so good and that car is a beast with a twin turbo V6.
Where can I get one?

lol, it ain't really that sleeper, considering all the front mods.

Plus, it has 650 written on the side........people aint gona think its the time are they ?

i hate those rims...so ricey looking.and that grill cover looks...err...ok ok.they shud have used the re kit.....simple n sweet.

I agree..the rims do not really fit the car (styling wise). They look too ghetto. Bah, it's uber fast..not to mention it's probably still comfortable. It's a pretty cool car.

They're ghetto as hell, but probably serving a purpose. They could potentially be reducing turbulence. Don't aske me how, but it would be pure pointlessity if they were just meant to look good.

okay i have a question...how much role does suspension play in achieving top speed?

I have never wanted the BMW M5 more.

lol ya they do look ghetto but who cares....when ur goin that fast no one can see the rims.....

okay i have a question...how much role does suspension play in achieving top speed?

i guessing a lot because i think it keeps the car stable and more aerodynamic....correct me if im wrong...

Dam. This thing is as fast as a Ferrari 599 GTB to 200kph (10.3 secs) and its faster than a Ford GT, LP640, SLR to 300kph!

okay i have a question...how much role does suspension play in achieving top speed?

i guessing a lot because i think it keeps the car stable and more aerodynamic....correct me if im wrong...It causes flow detachment on racing cars, which is why they are shrouded on racing sports cars. (It also reduces lift and makes a faux duct, improving the function of the front difusser and the radiators). I don't know if it would mean much on a car like this though, seeing as the suspension is hidden well inside the wheel well. I guess any flow deachment created by that would be beneficial.

Its a great car but I would seriously consider an RS4 over this one! Who agrees with me?!

so from those posts...h&r guys didn't have much of the achievement pie.....top speed is more with
a) aerodynamic design body
or
b) proper suspension setup?

Hmm, why did they use the 3.2V6? If they used the RS4's 4.2V8 and TT-ed it, it would be a lot faster. Even though its bloody insanely fast now.

The RS4 is already tuned to the max (with reliablility in mind) so they would blow it up if they tried to make it faster.

Its pretty insane almost as fast as an enzo and has 4 doors.

so from those posts...h&r guys didn't have much of the achievement pie.....top speed is more with
a) aerodynamic design body

I'd say aerodynamic design, because the shape of the body (as well as type of surface) determines how much force he need to exert on the car in order for it to be pushed through the air. On the other hand, a good suspension setup can limit body pitching, and can therefore improve the aerodynamic stability of the car.

For example, everyone knows about Renault's mass damper setup, which was essentially a mass built into a spring in the nose that would limit the pitch of the front end. By limiting the magnitude of the pitch of the front end, the car would then become more consistent aerodynamically, as the front end wouldn't move as much.

I would say that you would gain a greater top speed with an aerodynamically shaped car with rubbish suspension, then a car with superb suspension but having a rubbish shape.

Why did they block the Single Frame grille and the other intakes? That's just plain Veyron-esque cheating if that's supposed to make it go faster. Wouldn't the lack of intake air make it slower, despite improved aerodynamics?

Well they've done extensive mods on the front, and I guess at those speeds there would be enough of a volume flow rate of air to compensate for the reduced intake area. My guess is that larger intakes are needed for road cars because they aren't exactly travelling fast all the time, so need a greater intake area to get more air in.

They could potentially be reducing turbulence.

My guess would that they may do this, but my other guess is that the wheels would need to be somewhat asymmetrical in order to achieve a greater reduction in turbulence. For instance, the spokes could be shaped to cut through the air, or something similar. I mean I don't know much about wheel aerodynamics (or rotating object aerodynamics), but to me, those wheels don;t especially look like they would do a whole deal of turbulence reduction.

Its a great car but I would seriously consider an RS4 over this one! Who agrees with me?!

obviously no-one.. because that car does 0-100km/h in 3.8.. audi RS4, 0-100km/h in 4.8.. and with out the stickers, this is the perfect sleeper...

Yeah, I agree.... or disagree. I'd take an RS4 over it. It doesn't have all that plastic, it has nice wheels, no stickers and it will be more useable.
