In the market for something British, but aren’t satisfied with the “standard” options offered by Jaguar Land Rover? Arden can help.

The German tuner specializes in the UK’s finest, and has landed at the 2018 Geneva Motor Show with tempting enhancements for two of JLR’s top-of-the-line models.

Pictured above is the Jaguar F-Type SVR, which already stands at the pinnacle of Jaguar’s lineup. Arden takes it further by fitting it with a comprehensive aero kit, including a new front apron, grille, side skirts, rear apron… even new door handles. 21-inch wheels stand to reduce unsprung mass, mounted to a suspension lowered by 30 millimeters (about 1.2 inches) with grippy Continental rubber to help channel all the power to the tarmac.

And make no mistake about it: Arden AR 23 packs a lot of power. 703 metric horsepower, to be specific (up from the standard 575), with 644 lb-ft (873 Nm) of torque to back it up. The 5.0-liter supercharged V8 features new forged pistons, an upgraded supercharger, a new intake system, and a remapped ECU. Arden has also upgraded the F-Type’s interior with aluminum-coated textile, a leather and Alcantara steering wheel, and aluminum trim.

Those looking for more space and off-road capability may be drawn more to the AR 12 – Arden’s take on the flagship Range Rover. It features a full widebody kit, with front and rear aprons, side skirts, grille, and expanded wheel arches. The same engine has been similarly upgraded to 680 hp and 597 lb-ft (810 Nm) of torque, dropping 0.6 seconds off the 0-62 mph (0-100 km/h) time to come in at 4.9 seconds.

Giant 23-inch alloys stand at each corner, with a suspension dropped by 25 millimeters (about an inch) and an interior enhanced by diamond-stitched leather upholstery, aluminum pedals, Alcantara trim… the works.

Arden Automobilbau is showcasing both at the Geneva show, but you can check them out in the gallery below.
