Arden rebuilds the 4.2 l V8 completely new and sharpens the claws of this big cat by increasing its displacement. The displacement increase to 4.5 l is achieved by fitting a crankshaft specially produced for Arden, along with new con rods and pistons. Arden optimises the lubrication and the cooling and, in doing so, guarantees a long service life of the components, as it also does through its more than 20 years of experience in the field of Jaguar engine tuning. In conjunction with the modified intake and exhaust systems and sports catalytic converters, the fully recalibrated EMS produces an emphatic but harmonious power boost, whilst retaining the original exhaust gas classification. For drivers, these modifications translate into a vast increase in driving pleasure primarily due to the result of the compressor. Arden releases through the supercharged 4.5 l an impressive 480 hp / 353 kW and a mighty torque of 640 Nm at 3,850 rpm. This guarantees a confident acceleration from 0 to 100 km/h in 4,1 seconds! A top speed of 305 km/h (reached on the test track in Papenburg, Germany) makes the Arden AJ 20 the fastest Jaguar currently on the road.

In neutral, the Arden AJ 20 purrs as softly as a kitten. But watch out when it stretches out its claws! The Arden AJ 20 Coupe expresses its additional power in the form of a deep growl, produced by a sports silencer system with the four chrome-plated tailpipes. Upon request, the system can be extended at any time up to a performance-enhancing complete system that includes catalytic converters.
