Audi S5 Sportback Grand Prix with 375HP by Senner Tuning

The Grand Prix is Senner Tuning's take on the new Audi S5 Sportback. Starting with the engine, the German company brings output from the standard 3.0-liter TSI's 333 horsepower and 440Nm /325 lb-ft of torque to 375HP and 495Nm / 365 lb-ft. The power boost comes from a reconfigured ECU, the addition of a performance air filter as well as a custom sport exhaust system with four tail pipes.

The S5 Sportback Gran Prix also gets a set of sport springs that lower the ride height by up to 40mm or 1.58-inches and new two-piece 20-inch alloy wheels shod in 245/30 R20 tires up front and 295/25 R20 at the back.

Finally, the Audi's interior is revamped with a carbon fiber trim package.

ABT Powers Up and Stylizes New Audi A5 Sportback

ABT Sporstline has built its reputation on modifying just about anything on four wheels that comes out of the VW Group's plants. Their newest proposal concerns the Audi A5 Sportback which has been modified with a variety of aesthetic and performance goodies.

The tuner jazzes up the five door coupe's appearance with numerous aero add-ons, including a new front bumper, ABT's trademark grille, front fender air-vents and a rear apron with a diffuser shrouding chrome exhaust tips.

Customers can choose between 18-inch and 20-inch alloy rims which are available in two different designs.

For the time being, ABT offers power kits only for the A5 Sportback with the 2.0 TSI petrol and the 3.0 TDI diesel engines.

After the tuner gets its way with the powerplants, the entry-level 2.0 TSI's output is boosted from 180HP to a hardy 275HP while the 3.0-liter V6 diesel can be lifted from 240HP to either 282HP or 310HP. The most powerful version of the V6 diesel hits the 100km/h (62mph) mark in 5.8 seconds.

The tuner finishes off the package with a sport suspension and a high-performance braking system with either 345 mm or 380 mm disks and eight piston calipers.

Audi S5 Sportback with 3.0 Supercharged V6: Photo Album and Initial Specs

Ingolstadt has whisked the covers off the sportiest version yet of the A5 Sportback, the S5 that will be displayed for the first time at the 2009 Frankfurt Motor Show in September. The S5 Sportback uses the same 3.0-liter supercharged V6 engine as the latest-generation S4 sedan that cranks out 333 horsepower and 440Nm (324.53 lb.-ft.) of torque between 2,900 and 5,300 rpm.

The 3.0 TSI engine is mated to a seven-speed S tronic dual-clutch transmission that puts power to all four wheels through Audi's a Quattro drivetrain while a sport differential, which variably distributes power on the rear axle between the rear wheels, will be offered as an option.

The German firm cites a 0 to 100 km/h (62mph) sprint time of 5.4 seconds (S4 Sedan: 5.1 seconds) and an electronically governed top speed of 250 km/h or 155mph.

Audi says that the S5 Sportback returns a combined fuel economy figure of 9.7 liters per 100 km which is the U.S. equivalent of 24.25 mpg.

In typical Audi fashion, a subtle body kit that includes a deeper front bumper, aluminum-look exterior mirror housings, side skirts, specific grille and a small boot lid spoiler plus 18-inch alloys shod in 245/40 tires distinguish the S5 from its lesser A5 siblings.

Inside, a three-spoke leather steering wheel with contrasting stitching, the aluminum trim, gray dials and of course the sport seats covered with Silk Nappa leather let you know you're behind the wheel of a special A5.

Sales of the Audi S5 Sportback are pegged to start in Spring 2010 with prices set to start in Germany from €57,900.

Audi Confirms A5 Sportback and new A8 for 2009, Q5 Hybrid also in the Works

During his speech at Audi AG's annual shareholders meeting in Germany, Audi Chairman of the Board, Rupert Stadler, revealed that the automaker is planning to present the next-generation A8 in November and extend its range with the new A5 Sportback sometime in 2009. Furthermore, Stadler confirmed earlier reports that Ingolstadt based company is also working on a hybrid version of the Mercedes GLK rivaling Q5 SUV and that the A1 minicar is due for a 2010 market launch with the Q3 small SUV following in 2011.

This means that unless Audi has another surprise up its sleeves, the four-door coupe derivative of the A5 is most probably the new model that the maker said its preparing to unveil during the celebrative festivities for the firm's 100th anniversary in Germany on July 16.

The A5 Sportback is in essence the production version of the sleek-looking Sportback Concept that was first shown in Detroit in the beginning of the year. Expect to see a familiar Audi engine lineup, including the latest 2.0-liter TSI with 211HP, the 3.0-liter supercharged V6 with 290HP and a 3.0-liter V6 diesel cranking out 240HP.

"The A4 has attracted the largest share of customers loyal to the Audi brand. And a great number of them want to move further upward while carving out their own unique identity," said Stadler.

"The A5 Sportback is precisely what they're looking for. This vehicle will pose a genuine innovation in the B segment: a revolutionary vehicle concept offering the ideal blend of functionality and aesthetics"

As for the brand new A8 sedan (see the spy shots here), Stadler said claimed that it will be the sportiest model in its segment and that it will redefine people's notions of a luxury car's interior.

"We will also be presenting the next-generation Audi A8 and rest assured, Ladies and Gentlemen, it's going to be a sensation. The A8 remains Audi's flagship: it embodies our understanding of the word "premium"," Stadler told Audi's shareholders.

"The A8 will be the sportiest luxury sedan in its class – and set new standards with regard to interiors. Its precision and build quality are second to none. This model naturally means a great deal to us, because it played a greater role than any other car in the rise of the Audi brand. And we will unveil it to the world in a remarkable fashion in late November."
