Audi will roll-out its latest sporty Avant models between September 2012 and February 2013 – a supercharged V6 for the S4 producing 245kW/440Nm and the range-topping RS4’s V8 generating 331kW/430Nm. The S4, which is now available in South Africa, uses a redesigned 3-litre TFSI engine with a supercharger added for effect to propel the wagon from 0 – 100km/h in 5.2 seconds. Its top speed is electronically limited to 250km/h. QUATTRO PLUS S TRONICQuattro permanent all-wheel drive is standard with 60% of torque sent to the rear wheels in regular driving conditions, providing a rear-wheel bias for sportier performance. Should slippage be detected, however, the torque distribution can be shifted within seconds. Drive is channeled via a seven-speed S tronic dual-clutch transmission. Exterior changes over standard A4 Avants include signature aluminium-look wing mirrors, 19” light alloy rims, a tailgate spoiler and four tail pipes plus xenon plus headlights with daytime running lights. Inside the cabin, the instrument panel features grey dials with white needles while the interior is finished in black with brushed aluminium accents. The S4 Avant is now available in South Africa at a price of R637 000, which includes a five-year or 100 000km Audi Freeway Plan.For those with a stronger urge for sweaty palms, the latest RS4 Avant also comes with the giddying combination of a 4.2-litre V8, seven-speed S tronic and Quattro all-wheel drive with Audi’s crown-gear centre differential and a 40/60 front to rear axle bias. ROARING V8The RS4 Avant uses the same naturally-aspirated V8 engine seen in the RS5 and accelerates from 0 – 100km/h in 4.7 seconds and has a top speed governed to 250km/h. Launch control is available for fast starts. Audi’s drive select system is standard on the RS 4 Avant and allows the driver to switch between three modes – comfort, auto and dynamic – to determine the steering, transmission and S tronic characteristics. It can also vary the sound of the exhaust system and double-declutching when downshifting in dynamic mode. The exterior design is distinguished by its single-frame grille with matte aluminium-look surrounds, LED daytime running lights and a bulky bumper with a front splitter. The RS4 Avant is 20mm longer and 24mm wider than the A4 Avant, but sits 20mm lower for better ground-hugging performance. The RS4 Avant’s cabin is finished in black with carbon and aluminium inserts for items such as the pedals and footrest, and the RS4 badging on the door sills. The driver information system includes an RS menu with a lap timer and oil thermometer. Audi connect, which essentially turns the car into a Wi-Fi hotspot, is available as an option.The new Audi RS4 will only be offered as an Avant model and will be introduced in South Africa in February 2013. Pricing will be made available will be made available then, Audi SA said.
