GeigerCars extracts more muscle from the ATS-V Coupe, but other tuners are getting even more out of the 3.6-liter biturbo V6.

German tuner GeigerCars specializes in upgrading American vehicles mainly for a European audience, and the company’s latest project aims to make the Cadillac ATS-V Coupe into something even more potent. The firm’s Black Line styling kit gives the Caddy meaner looks that better fit the extra power, too.

GeigerCars’ 7,900-euro ($8,860) performance kit pushes the ATS-V Coupe’s 3.6-liter biturbo V6 to 502 horsepower (374 kilowatts), which is a 38-hp (28 kW) gain over the stock 464 hp (346 kW). Torque jumps to 486 pound-feet (659 Newton-meters) versus 445 lb-ft (603 Nm) from the factory. An eight-speed automatic still sends the muscle to the rear wheels. The tuner doesn’t specify how these upgrades affect the Caddy’s acceleration, but the top speed jumps to 194 miles per hour (312 kilometers per hour) from 189 mph (304 kph) out of the showroom.

The kit’s parts include a stainless steel cat-back exhaust with controllable valves for managing the sound, an X-pipe, and 110-millimeter (4.3-inch) tailpipes. The company also retunes the engine’s software for optimization of the fueling, ignition, and turbo boost.

GeigerCars also has components available that give even more attitude to the already aggressive ATS-V. The firm’s 1,090-euro ($1,220) lowering springs slice 25 mm (one inch) off the ride height, and they give the coupe a road-scraping appearance ­– as these photos show. The 19-inch OZ Leggera wheels for 3,990 euros ($4,480) fit well with the squatter look, too. The company’s 750-euro ($841) Black Line pack completes the menacing transformation by adding darker trim to the outside.

While the German company’s upgrades look great, other tuners are finding ways to get even more power out of the ATS-V. For example, Hennessey Performance in the United States offers a kit that allegedly takes the Caddy to 550 horsepower, which is 48 hp (36 kW) more than GeigerCars and 86 hp above the amount that comes from the factory. Hennessey’s improved parts include new engine software, a cat-back exhaust, and an updated induction system.
