Audi TT Roadster

The Audi TT Roadster is a convertible two-seater, mechanically similar to the TT coupe version with which it shares the same range of engines and gearboxes. The TT Roadster is more than 4000 € a TT Coupé, for the same engine.

Like the coupe, the Roadster gives the impression that is well done, your computer may be plentiful and very pleasant to drive. It has the feel and feedback that is not the most sporty or comfortable, but in between that makes it successful in both respects.

Is available from 39,300 hp to 200 hp engine and six-speed manual transmission. Therefore, it costs more than an Alfa Romeo Spider 185 hp and less than a BMW Z4 roadster 218 hp (Convertibles tandem relationship between 170 and 230 hp).

In mid-July 2008, Audi will start selling the version with the less powerful engine, a 1.8 TFSI of 160 hp. A little earlier, in late June, came the diesel version, which has the 2.0 TDI engine from 170 hp, so the TT is the first model of the Volkswagen Group to use this variant of the engine with the injection system through Common (some driving impressions of these engines in the coupe version).

The other three versions are a 2.0 TFSI with 200 or 272 variants of a 3.2 hp and 250 hp six-cylinder naturally aspirated, all other engines are tetracilindricos and supercharged by a turbocharger. 2.0 TFSI 272 hp, called TT S, trafficking in another article.

It has a canvas roof that opens and closes by electric motors. The total process to open or close it takes 12 s (low) and can be carried out with the car running, if the speed is below 50 km / h. In other markets there is a different hood, manual and less insulating layers of noise.

The hood is bent on 'Z' folded and left behind the only two seats have the car. Moon has a built in, you do not need a cover for the hood when folded and can be hard fitting a roof.

Series, there is a windbreak behind the protective anti-arms. It differs from others (either network or plastic) that puts and takes off (up or down) by an electric motor, which facilitates its use under any circumstances.

From the dashboard to the seats, the carrier is similar to the closed version. Just change what's behind them: the two rear seats, which only serve to transport children, have been eliminated. In the space they occupied is where the roof is covered when the car is convertible.

The driving position is satisfactory, with all the controls well placed. Seats, the car we tested were upholstered in Alcantara, holding the body well and have a strong filler that makes comfortable on long journeys.

The boot volume is 250 l, whether the hood is as is, he lost 40 in relation to the existing trunk coupe and earns the same with the previous Audi TT Roadster.

It has no side-curtain airbags to protect the specific upper body, but side airbags in the seat-type head and thorax. These airbags, the front, stability control and traction, air conditioning, alarm, computer or sports suspension are standard.

In the list of options as there are double xenon headlights (standard on the version 3.2), adaptive lighting, leather upholstery, various sound equipment, web browser or Bluetooth connection for mobile phones, among others.

Most mechanical components are shared with the coupe, including engine and transmission. The version with four-cylinder engine with direct injection, turbocharged 200 hp and is front-wheel drive. The six cylinders in V close indirect injection, naturally aspirated and 250 hp, has traction total.

From what we've seen in the unit we tested the Audi TT coupe with 200 hp engine, it makes little sense to choose the 250 hp if you are looking for more benefits, because the turbocharged four-cylinder engine makes the car faster than six-cylinder naturally aspirated (measurements). In addition, fuel consumption is lower.

In both cases, the gearbox is standard six-speed manual is available and an automatic S tronic. This box is automatic dual-clutch, the DSG from Volkswagen, and we are highly recommended for its smooth functioning.

Optionally, the TT can carry a variable fluid damping electroviscoso which costs € 1450 (about another device of this type). This suspension has two programs running, a normal and sporty. The first is at least equally hard with the suspension as standard. With the second, which is selected with a button beside the lever of change, it becomes very hard and is used only on roads with asphalt.

In 2008, the Roadster will have a new four-cylinder engine that has launched the A3, with 1.8 liter displacement and 160 HP maximum
