The redesigned 2007 Audi TT again gets a drop-top sibling, with the new TT Roadster carrying on the distinctive lines of its predecessor while boosting performance and dynamics.

Compared to the model it replaces, the new TT Roadster is 137 mm (5.4 inches) longer with the wheelbase stretched by 46 mm (1.8 in.). It is also wider by 78 mm (3.1 in.), and is marginally taller (+ 8 mm).

The increase in body dimensions benefited luggage space, which expanded from 210 to 250 litres (7.4 to 8.8 cubic feet). An electrically powered spoiler rises up out of the rear deck lid when vehicle speed reaches 120 km/h.

Standard storage facilities, such as deep compartments in the doors and two cup holders, can be supplemented with a storage package comprising three storage nets and four extra compartments. Active owners can further supplement their storage needs with a pass-through to the trunk, including a ski bag (a first in the roadster segment).

Although also built with Audi's Space Frame technology, the new roadster has select steel components for strength, mostly located toward the rear of the vehicle to maintain optimal weight distribution. The bulkhead behind the passenger compartment is steel in order to anchor the steel roll-over hoops. The windshield frame is also steel to maintain the integrity of the passenger compartment in the event of a rollover. The result is an improvement in torsional rigidity translating into decreased body shake and improved handling.

The 2007 TT roadster comes in front-wheel drive powered by a 200-hp turbocharged direct-injection 2.0-litre 4-cylinder or all-wheel drive model with power delivered by a 250-hp 3.2 V6. Both use a 6-speed manual gearbox with the sequential-shift S tronic automatic optional.

Both engines feature a broad torque plateau: the 4-cylinder generates 206 lbs.ft of torque from 1800 through 5000 rpm, while the V6 makes 236 between 2500 and 3000 rpm. According to Audi, zero to 100 km/h takes just 5.9 seconds in the TT 3.2 quattro, while the TT 2.0T takes 6.5 seconds.

The V6 model comes with a fully automatic cloth top that stows itself flush with the bodywork just in front of the trunk in just 12 seconds. The 2.0T features a manual drop top with the one-button automatic controller optional. An electrically operated mesh wind deflector is optional.

All TT Roadsters employ a front McPherson strut suspension and rear four-link with side-by-side shock/spring setup. All ride on 17-inch alloy wheels, which can be fitted with run-flat tires.

The optional Audi magnetic ride adaptive damping system uses magnetic particles in the shock fluid that are electrically charged at the push of a button to alter damping characteristics in order to alter ride and handling characteristics.

Audi's electronic stabilisation program (ESP) has been optimised for a sporty driving style with neutral to slightly understeering characteristics.

Inside, deep-set standard Alcantara/Leather sports seats provide firm lateral support for both the driver and passenger. The standard leather-wrapped sport steering wheel features a flat-bottomed rim to aid entry and exit. The optional Impulse leather upholstery with its distinctive topstitching is back.

Standard equipment includes the new "concert" audio system with satellite radio, a driver information system, ventilated and heated sport seats, heated outside mirrors, sport seats and satellite radio preparation. Options include a DVD-based navigation system, Bluetooth cellular hook-up, Bose surround-sound system.

Audi has yet to announce pricing, but will reportedly keep pricing close to that of the current generation. The TT Roadster is due for launch in the second quarter of 2007.
