Audi R8 Spyder 4.2
Audi is adding another model to its R8 high-performance sports car lineup: Hot on the heels of the R8 Spyder 5.2 FSI quattro comes another model with a V8 engine. The 4.2-liter FSI produces 316 kW (430 hp) and launches the open-top two-seater to 100 km/h (62.14 mph) in 4.8 seconds on its way to a top speed of 300 km/h (185.79 mph). The engine is mated to the R tronic sequential manual gearbox; quattro permanent all-wheel drive is standard.
The R8 Spyder 4.2 FSI quattro has a lightweight cloth top with a fully automatic drive. Its body is an aluminum Audi Space Frame with large-area components of carbon fiber composite material. A fit and finish typical of Audi, excellent everyday practicality and optional high-end technologies – from LED headlights to seatbelt microphone – complete the profile of the model athlete.
The free-breathing 4.2 FSI is a high-performance engine such as can be found in racing. It delivers an experience that enthralls all of the senses – with spontaneous, voracious throttle response, with its easy revving, with hefty torque, prodigious power and sonorous, voluminous music.
The V8 accelerates the R8 Spyder from zero to 100 km/h (62.14 mph) in 4.8 seconds and on up to a top speed of 300 km/h (185.79 mph). Both values apply for the manual transmission and for the R tronic. At Audi, dynamics also always means efficiency. The R8 Spyder 4.2 FSI quattro with the R tronic consumes on average 13.9 liters of fuel per 100 km (16.92 US mpg); fuel consumption with the manual transmission is 14.9 liters per 100 km (15.79 US mpg). A recuperation system that recovers energy during braking is standard. The forced oil pump of the dry sump lubrication system features various suction and discharge stages for load-dependent operation.
The Audi R8 Spyder 4.2 FSI quattro comes standard with a manual six-speed transmission. It works together with a compact dual-disc clutch and can be shifted extremely precisely and easily with short throws. The shift lever is made of polished aluminum, the open gate of stainless steel.
The R8 Spyder 4.2 FSI quattro is optionally available with the R tronic, a highly efficient sequential six-speed transmission. Shift commands are transmitted electrically; a hydraulic system changes the gears and manages the clutch. The R tronic offers both an automatic and a manual mode, both of which allow the driver to choose between two shift programs.
The R8 Spyder 4.2 FSI quattro has a cloth roof – a classic feature typical of Audi and without compromise for a high-performance sports car. The soft top’s approximate weight is a mere 42 kilograms (93 lb); it thus keeps the vehicle’s weight and center of gravity low. The top takes up little space when open, and is a harmonious design element when closed. It tapers off to two long, slim fins that extend to the trailing edge of the car and have an elongated contour similar to the fixed roof of the R8 Coupé.
The outer skin of the top is a leakproof textile fabric. A headliner covers the frame, which is made primarily of die-cast magnesium and aluminum. The soft top is fully suitable for high-speed driving. When driving at moderate speeds with the top up, interior noise levels in the R8 Spyder are barely higher than in the Coupé. The cloth top has an electrohydraulic drive that uses a system of actuators, hinges and hooks to open and close the top within 19 seconds, even while driving at speeds up to 50 km/h (31.07 mph). When opened, the 1.7 square meters (18.30 sq ft) of fabric folds in a Z-shape into its storage compartment over the engine. The CFRP compartment cover moves on two seven-joint hinges. The precise mechanical interaction of the two components is a pleasure to watch.
