Jaguar XJ40 Series

After nearly a decade of study and refinement, a new XJ debuted in 1986, the series "40". Despite the voices of evil (who argued was another facelift) the XJ40 was completely new car. New Age of the line (more aerodynamic and more "smooth" despite the obvious stylistic continuity with the Series 3, which also remained in production), was the new rear suspension with lower triangular arms and, on some versions, auto-leveling recovery with automatic leveling, new interiors were the (very rich and opulent), new engines were inline 6-cylinder DOHC. For the first time the Jaguar was also a massive electronics applications (on-board computer, check-panel, management of air conditioning, ABS). The range consisted of two engines and two versions (basic and Sovereign).

At the base of the range we placed the 2.9, powered by the 6-cylinder 2919cc from 165cv with electronic fuel injection and tested at 2 valves per cylinder, while the top is placed the 3.6, move from 6-cylinder with 24 valves tested to 3590cc powered injection 225cv. Both engines, all-aluminum, could be combined with 5-speed manual gearbox or a new automatic 4. The 2.9, however, was only available in the standard layout (you can tell the 4 headlights circular), while the 3.6 could be based or Sovereign (with self-leveling rear suspension, better-finished interiors, equipment and enriched rectangular headlights.)

The smaller engine, inadequate to the weight of the car, was almost ignored by customers who s'orientò mass on 3.6, mostly in Sovereign version with automatic transmission. In 1990, the home of Coventry, passed at Ford since 1987, ran for cover. The version 2.9 was replaced by 3.2, with 24-valve engine of 3239cc (201cv), while the displacement of 3.6 liters grew to 3980cc (235cv), originated the Sovereign 4.0. The 3.2 was available in both standard and Sovereign.

Was launched in 1991 XJR 4.0, equipped with an enhanced version of 251cv, 6 cylinder 4 liter. This version was recognizable for the lowered suspension and sports interior trim (dark maple wood trim, sport seats).

In 1992, after a series of modifications to the engine compartment (designed originally for non-host V-engines, to prevent the installation of the V8 Rover), debuted the XJ40 V12. The engine was the same as the Series 3 (coming out of the list), but thanks to the increased displacement (5993cc), the power touched the 318cv. Obviously the XJ12 Sovereign was available only in version with automatic transmission. In 1994, the Series 40 was replaced by the X300 series.
