Introduction
Is the TT really front wheel drive? What an outstanding job of making front wheel drive work in a performance car. We drove the Audi through mountain roads with switchback turns and rises that left some passengers heading for the Dramamine. We drove the Audi at redline more than we care to admit and stomped hard on the 4 wheel discs until the rotors were hot enough to fry an egg. We cranked the steering on tight maneuvers with the throttle wide open to monitor the ASR (anti-slip regulation) in operation. And when we gathered around the campfire to compare notes it was a resounding "IT"S OK". We were more impressed with how refined this car is than how quick the 180hp model was we tested. 

Every time we drove the car the conversation would unintentionally center around how this car did compared to the Honda S2000 we tested 6 months ago. If you plan to drive like Juan Montoya then buy the Honda, if you want a refined sports car that provides a stable, smooth platform then consider the TT. Well, that said lets move on to the meat and potatoes. 

The Lake Silver Metallic 2001 Audi TT Roadster we tested had a base price of $32,850. To that we added the Audio Package for $1,200, the Premium Package for $1,450 and the power top for $800. With the destination charge of $525 the MSRP totaled out at $36,825. If we were to purchase this car we would omit the power top and save the $800. 

This price is a tad higher than the Honda but the Audi has some nice standard features such as front and side airbags, anti-theft, headlight washers, glass rear window with defogger, heated outside mirrors, climate control with dust and pollen filters, tilt/telescopic steering wheel, galvanized body w/aluminum hood, 120 watt 7 speaker stereo and wiring for the ever essential telephone. The 4 year 50,000 mile warranty also covers all scheduled maintenance and 4 year roadside assistance. 

The basic layout of the vehicle is the typical unitized body with front wheel drive, struts up front with 3 point lower control arms and a torsion beam trailing arm rear axle. Sound like a VW golf, New Beetle or Audi A4? If you want the fully independent rear suspension you'll need to buy the new 225HP Quattro car. 

Interior
It's difficult to find fault with the interior when Audi really went the extra mile to spoil the occupants. The seats in our tester were leather clad and provided excellent bolstering and lumbar support. They also provided excellent lateral support without sacrificing comfort on those long road trips. Pedal position was excellent and the clutch had good feel without excessive travel. The dead pedal is the size of Wisconsin so you won't have to hunt around for it with your left foot. The adjustable steering column does it's job for most size drivers so there should be no complaint there. Instrumentation is first rate and in direct view of the driver. Below the hamburger warming light (it really does look like a heat lamp) on the center console there are 3 switches, one of which disables the motion sensors in the top to prevent the alarm from being activated if you leave your pet locked in the car (those baseball glove stitched seats may look like a big rawhide chewie). 

The controls for the heated seats pop out and rotate with good feel and function. The climate control dials push/pull and jog left and right also with the feel of quality. Our car had the optional concert sound stereo and provided everything you could want from a stereo. The aluminum cover nicely hides the stereo when your away from the vehicle. The use of aluminum trim throughout the interior provides a feel of quality and enhances the overall appearance. We hate to say anything bad about the interior because it really is of the highest standard but the cupholders are not placed very conveniently. We know some folks don't think a car like this should have cup holders but that cappuccino has to go somewhere. Once again we end up making a comparison between the S2000 and the TT with the Audi winning this round hands down. Driving the Honda is a great experience and we recommend it to everyone but where the Audi lacks the power of the Honda it makes up for it by coddling the driver. If your in for a long trip you'll be thankful you chose the TT.

Engine and Gearbox
Power comes from the 5 valve turbocharged 1.8 liter 4 Cylinder making 180 bhp @ 5500 Rpm's. Doesn't look all that impressive huh? Well maybe the fact that the 173 lb-ft of torque comes in at 1950 Rpm's and runs out to 4700 will brighten your day. This is the same basic powerplant as the Audi A4 and the new VW Turbo Beetle except those cars only pump out 150 bhp. To grab the extra 30 horses Audi had to change the turbocharger, intake manifold, exhaust manifold and pistons. The biggest gain was in the redesign of the intake manifold that creates a tumbling effect on the turbocharged air as it enters the combustion chamber. This in essence increases the combustion process by improving the mixing of air and fuel. The result is increased engine efficiency and lower exhaust emissions. 

The Bosch Motronic ME 7.5 engine management system keeps the little 1.8 running smoothly and employs drive-by-wire throttle operation. This system also handles the electronically locking front differential (EDL) and the standard traction control called ASR (anti-slip regulation). Audi uses the KKK Type K03 turbocharger that produces a maximum of 9.6 psi of boost. Turbo lag is reduced to such a low rpm range that the average driver will not take notice. This in part is accomplished by the engines 9.5:1 compression ratio which is rather high for a production turbo motor. Shifting the 5spd gearbox (6sp on 225hp version) is accomplished through the use of a rigid wire cable setup instead of steel rods. Don't worry though because the TT shifts better than most cars we have driven. 

Driving Impression
Every car has it's own peculiarities that make it feel and drive a certain way and the TT is no exception. Even though the production TT looks a great deal like the pre-production prototype we suspect the Audi engineers were burning the midnight oil when it came to the suspension. Did they get it right? You bet they did, this is not your typical front wheel drive econobox and a day driving around some mountain passes will clear that up in a big hurry. Expecting the traditional front wheel drive understeer? The kind that would push you right out of that apex and into your insurance agents office? Nope, this car tracks through the turns with authority whether you are on or off the gas. Sometimes you just have to shell out the bucks if you want the suspension to be right and in this case you won't be disappointed. 

We haven't tested the Quattro version yet so we can't give you our impression but if we had to guess we would say it's going to be good. Did we say you won't need your kidney belt when you ride in this car? The ride is very compliant and left us feeling relaxed after long periods of time in the car. We mentioned before that we could not help compare this car to the Honda S2000 because it pretty much targets the same audience but after spending time in both vehicles we can tell you they are very different machines. Even though the Honda is faster and more fun to drive at speed it does lack the small refinements in the suspension and interior that make the Audi more pleasant for general outings. 

To be more specific we found the seats to be more comfortable, the interior controls more user friendly (even though there is no red starter button) and the ride more catering to the passengers. Every time we drove the Honda we felt the need to run the car hard and appreciate it's performance attributes. The Audi was just the opposite. Every time we drove the TT we felt like we just wanted to cruise along at a good clip and enjoy all the twisties we could find. When we pushed the TT to it's limits it remained perfectly controlled but never left us feeling satisfied. The 225hp Quattro may take care of the speed concerns and add all weather traction to boot. 

On one of our photo shoots we ended up parked next to a new C5 Corvette and couldn't help notice the contrast. The Corvette dwarfed the Audi and really is such a different car that we shouldn't really compare the two. On the other hand for a little more money the Corvette can open up a whole can of whoop ass on the TT. When it comes down to writing the check, folks should consider what it is they want. If it's pure power and speed they may do better with the S2000 or the Corvette but if it's a refined open roadster that never leaves you fatigued than the TT is a sure bet. We would take the TT back anytime as a long term tester but there might be a fight in the office over who gets it first.

So what the heck does TT stand for anyway?
That would be "Tourist Trophy" as in Great Britain's historic racing series of the Isle of Man. 

Stuff We Liked:

  • Good low speed response from the engine.

  • Cool looking roll bars that are an integral part of the chassis.

  • Killer stereo (concert sound).

  • Hamburger warming light under dash (just kidding, it's just a dash light but it does look like a heat lamp).

  • Rigid body structure (very little cowl shake).

  • Very high grade interior materials 

  • Shifter

  • Excellent handling

  • Excellent ride

  • 22mpg city 30mpg hwy

  • Standard ABS and ASR

  • 100bhp per liter

  • Car held true to the original concept.

Stuff We Didn't Like:

  • Power top is not necessary because it's slower than the manual top and you will need to get out to install the boot anyhow.

  • For how well the car handles it could use more power.

    • 0-60 mph in 7.4 seconds

    • 0-80 mph in 13.3 seconds

    • 0-100 mph in 21.8 seconds

  • Power wind blocker behind the seats doesn't block that much wind.

  • 17" wheels should be standard
