The Viper ACR (American Club Racer) was developed with a single purpose: to create a street‑legal car capable of competing with dedicated race cars on the world’s most demanding circuits. Dodge engineered the ACR with a massive aero package, adjustable suspension, and weight‑reduction measures that transformed the already formidable Viper SRT‑10 into a precision‑focused track machine.

In 2009, this engineering philosophy culminated in a headline achievement: the Viper ACR set a production‑car lap record at the Nürburgring Nordschleife, proving that an American V10 supercar could outperform some of the most advanced European exotics of its era.

Under the hood sits the iconic 8.4‑liter all‑aluminum V10, producing 600 horsepower and 560 lb‑ft of torque. Power is delivered through a 6‑speed manual transmission, staying true to the Viper’s raw, driver‑focused character.

The ACR package elevates performance through:

• KW adjustable coilover suspension

• Massive Brembo brakes

• Track‑tuned aerodynamics generating over 1,000 lbs of downforce at speed

• Lightweight components including forged wheels and reduced‑mass interior elements

The result is a car that rewards precision and skill, offering one of the most authentic analog driving experiences of the modern era.

Driving the Viper ACR is an immersion into mechanical honesty. There are no drive modes, no electronic aids, and no filters between the driver and the chassis. The steering communicates every texture of the road, the suspension responds directly to driver input, and the V10 delivers torque with immediacy.

The aerodynamic package isn’t decorative it actively shapes the car’s behavior. At speed, the ACR feels planted and stable, allowing the driver to carry extraordinary cornering loads. This is the rare kind of car that teaches you how aerodynamics, mechanical grip, and weight transfer work in real time.

Inside, the Viper ACR maintains a purposeful, minimalist cabin designed around driving. The layout is simple, functional, and free of unnecessary weight. Supportive sport seats, analog gauges, and a driver‑centric cockpit reinforce the ACR’s mission as a track‑ready machine that remains fully street legal.

As one of the most celebrated performance cars of its generation and the final era of the naturally aspirated V10 American supercar the 2009 Viper ACR has become a highly sought‑after collectible. Its engineering significance, Nürburgring pedigree, and analog purity make it a standout piece for enthusiasts and collectors alike.
