2008 Audi S5

Almost anyone can spot a Mercedes-Benz or BMW, if only because they have iconic front styling. Audi's front end, with its relatively new 1930s-style grille, isn't as familiar. The swift new Audi S5 all-wheel-drive coupe looks stunning, but many people will probably stare at it and wonder who makes it.

Wider Audience Needed
Car buffs know Audi is upscale, with outstanding engineering and great interiors, and the $50,500 Audi S5 should enhance that automaker's reputation in affluent circles.

Still, the S5 is a car you buy to impress yourself. Most neighbors and acquaintances will be more taken with Mercedes or BMW nameplates, since both makers have maintained large coupes in their lineups. Audi hasn't offered a coupe with an adult-sized rear seat since its 1991 Coupe Quattro.

A Sharp New Coupe
My test S5 drew considerable attention with its striking, exclusive "Phantom Black Pearl Effect" paint. Its matching black interior also had tasteful brushed aluminum trim and other uptown touches.

The S5's sleek, low-slung body results in an interior that's tighter than a comparably sized sedan's. But then, coupes are more about sex appeal than practicality. The interior of the S5 has two separate rear seats, adding to its sporty appeal, although knee room is tight for a 6-footer behind the driver.

Outstanding Engine
The smooth, sophisticated, direct-injected 4.2-liter V8 generates 354 horsepower and 325 lb-ft of torque. It propels the car to 60 mph in 4.8 seconds and has a continuous power buildup. The S5 reportedly tops out at 155 mph, and my test car felt as if it could easily reach that speed.

The throaty sounding V8 exhales through four tailpipes, and is hooked to a 6-speed manual gearbox, which shifts positively but can be occasionally notchy. The clutch has a long throw, but a linear action. An automatic transmission becomes an option this spring.

Weighing in at a hefty 3,891 pounds, the new Audi's fuel economy is only 14 mpg in the city and 21 on the highway, resulting in a $1,300 gas guzzler tax.

Impressive Ride
If feeling lazy, an S5 driver need not spend much time with the gearbox. With 325 lb-ft of torque available at 3500 rpm, 65-80 mph passing can be done in sixth gear with no need for a downshift. The S5 also accelerates easily in sixth gear from 35 mph to highway speeds.

A long 108.3-inch wheelbase let Audi move the engine rearward for better weight distribution and a shorter front overhang. The result is less understeer and sharper handling. A rigid new chassis, sport-suspension, super-wide 35-series tires on big 19-inch wheels and a stability system easily handle all S5's power and torque. So do anti-lock brakes, which have good pedal feel.

The steering is quick and precise, but almost too light at low speeds. However, it tightens up at higher speeds for better control. The firm, supple suspension shrugs off most road imperfections, but can feel a little stiff on poorly paved roads.

Luscious Interior
The S5 is packed with comfort and convenience items. A leader in auto interiors, Audi has outdone itself with the S5. Along with the usual power accessories, the quiet, driver-oriented cockpit has automatic dual-zone climate control, heated front sport seats, cruise control and a 10-speaker, 180-wattt sound system.

A sunroof is standard, but it just tilts and doesn't slide—making some wonder why Audi bothered to install it. Safety items include front passenger side and knee airbags and a rigid body shell with special energy-absorbing zones.

Expensive Extras
Costly options in my test S5 included an $850 Bang & Olufsen premium sound system with 14 speakers, and a $1,700 Technology package with a handy rear parking system and rearview camera. A $2,390 navigation system has a "music interface" that makes working the sound system a chore.

The no-nonsense white-on-black gauges can be quickly read, and a digital speedometer backs up the regular speedometer. There's a mix of large and small climate controls and strategically placed front cupholders. The large trunk has a rather high opening, but can swallow many various-sized items. The rear seat backs flip forward and lay flat to enlarge the cargo area.

The new Audi S5 is a treat for all the senses. It isn't inexpensive, but after spending time in this slick new coupe, most buyers will likely feel it's worth every dime.
