Unassuming Audi S4 is a hot rod in disguise

They are stealth hot rods, European versions of American muscle cars, in milder shells. They go unidentified by the general public because each retains its European elegance and Teutonic stance, a certain cachet of class and subtle flair.

Yet, in hot rod form, they possess what the late Globe columnist George Frazier coined “duende,” a bold attitude and consummate class that sets them apart.

In basic forms, the BMW 3 Series, the Mercedes-Benz C-Class, and the Audi A4 are fine, even sporty automobiles. Yet to engineers with an eye for performance and buyers who want subtle but ferocious power, they are inchoate mechanisms in need of duende.

Enter the performance seekers — for whom money is not a huge obstacle — who would not be caught dead in a modern Corvette, Dodge Viper, or even a wonderfully restored American muscle car classic such as a late ’60s, early ’70s Dodge Charger R/T with a honkin’ 426 Hemi under the hood.

For them, the hot-rod engineers at German companies offer a redo of the C-Class Mercedes as a C32 AMG at 349 horsepower. At BMW, the 3 Series, the most benign of US-sold Bimmers, is turned into a BMW M3 that cranks out 333 horsepower. And today’s test car, the Audi S4, is a hot rod that results when a 220-horsepower A4 falls into the hands of performance engineers who crank it up to 340 horsepower.

The way the Audi folks accomplished this is somewhat counterintuitive in these days of reborn Hemis, superchargers, and turbocharging.

Turbos are nice, but I have found them to run thin on the torque line. The last S4, in fact, had twin turbos and delivered 250 horsepower from a 2.7-liter engine.

“We don’t need no stinkin’ turbos,” declared the folks at Audi, who dropped into the small S4 their big engine. The powerplant is a 4.2-liter, V-8 (no turbo nor super-charger), that delivers 340 ponies into a car that a 4-cylinder may well move along just fine.

That engine is mated to a 6-speed manual transmission (great, short clicks up and down) and, coming to the United States in the spring after the car’s appearance here this fall, a 6-speed Tiptronic, flicked from the steering wheel.

Seat yourself in the heavily bolstered Recaro bucket seats (forgetting for a moment that this is a four-door sedan), notice the industrial gray Kevlar-look appointments, and sense that your mission is one of stealth.

You are off, quick as you dare, in a thick torque band, no turbo windup to wait for. Again, this is old hot-rod muscle in yuppie skin.

There is slight understeer (accentuated in my test by wet roads) in deliberate hard cornering. Easily managed. And I could not wiggle the rear, even while trying. Even with traction/stability in place, I sensed that the car would not intrude on my intent until I had neared the edge of control. Other traction/stability sys tems step in way too soon, fudging the fun factor for those with a sweet tooth for twitchy performance.

The suspension did not feel as stiff as I experienced in the M3 (I can’t comment on the Mercedes since I don’t get to drive them much these days) yet it sat very flat in hard corners and was scalpel-like in highway passing.

The brakes — 13.4-inch discs up front, 11.8-inch discs in the rear — brought the car to chest-constricting stops.

And one advantage this car has in New England (and in performance mode) is that it is all-wheel-drive.

You could own this car in New England and actually drive it in winter.

And it also comes in a wagon version, the Avant. Now there’s a way to bring home the groceries.

  • Best mix of sport and luxury.

    Reliable car that is fast and technologically advanced for the model year. This car is on many enthusiasts bucket list. Engine has not been tampered with. Interior still smells like new leather.

  • 4.2 Liter in line V8 delivers superior power

    classic styling and comfort from a true 4 seat convertible. This was one of the last S4 models with a V8 and is considered to gain value in years to come.

  • Can be great started out a little rough

    I bought my s4 for 3400 out the door with 147k miles and i am now about 11k in to it in repairs mainly being the timing chain and clutch replacement as well as getting a missfire fixed and engine mounts replaced Other then those things the car is great it has the power to get up and go not to mention the handling while "not as great" as the bmw's of it's time if yoy drive it right you can still pull off just about the same things

  • It?s hard to get rid of this beauty

    I know it?s not the most advanced, most tech, most powerful vehicle to date. But it has character. I love the way it held up for being 2004 and loved the feeling i get when I?m behind the wheel. Unbelievable performance for such a heavy car. It will do things that would seem very un characteristic of a 4 door sedan. Gas mileage was my only complaint but silenced as soon as you step and hear the v8. Very classy and subtle car. Reliability was good when we worked the kinks out of the major and common problems.

  • A car for all seasons and most reasons

    In the Avant (wagon) body style, the 2005 Audi S4 is a great all-arounder with ample performance to delight drivers. Ergonomic design stands up to this day as excellent, with an exception to a lack of proper cup holders, remedied quickly in the 2005.5 mid cycle refresh. 4.2 liter V8 motor revs rise and drop exotically compared to domestic contemporary V8s, challenging even seasoned manual transmission purists to step up their heel-toe game. Overall exterior styling remains handsome to this day. This owner is only apprehensive of numerous ominous forum discussions warning of failure prone timing chain guides leading to costly engine-out repairs with no apparent preventative maintenance.

  • Pure fun to drive

    Absolutely one of the funnest cars I've owned. Pure joy to drive. This S4 is a wolf in sheep's clothing. Instead of the turbo 4 in the A4, this one comes from the factory with a 340hp V8. Just turn the key and you'll know immediately this is not your typical little convertible. Matched to a close-ratio 6-speed manual transmission, the joy of driving comes quickly. They haven't had a V8 in a small convertible since 2005 so theses are hard to find.

  • Funnest car I've ever owned

    Great car for anyone. Safe, fun, and great looking. A real head turner. Extremely well designed and built. Very low maintenance. Low marks for gas mileage but who buys a V8 car for great gas mileage. This one is fast.

  • Great car if timing service has been completed

    I love the car over all. Can be pricey to maintain if you don't have the right mechanic or know how. Timing service is a big job on these cars and common. If buying one make sure the timing service was completed or be ready to spend a large amount to have it done
