We have a full set of details about two new package options for the Jaguar XKR coupe, but are they worth £4,000? The story, with pics, inside.

Jaguar will introduce two new packages for the Jaguar XKR Coupe, the company confirmed today.  The automaker will market the Speed Pack and Speed & Black Pack in the UK at costs of £3,500 and £4,000, respectively.

The two kits will only be available on the XKR Coupe.

When customers purchase the Speed kit, they will get a car with an electronically limited top speed of 174 mph (280 km/h) instead of 155 mph (249 km/h).  The company states that a "revised front aerodynamic splitter and larger rear spoiler" are needed to guarantee stability with the new top speed.  At higher speeds, the car will be a bit less responsive to steering wheel movements.

Also included are 20-inch Kasuga alloys with red brake callipers visible from outside.  Chrome lines ring the windows, grille, exterior vents, and trunk.  The rear diffuser and side sills are also painted in body colour, including Kyanite Blue, Liquid Silver, Lunar Grey, Polaris White, Salsa Red, Spectrum Blue, and Ultimate Black.

£500 more gets you glossy black 20-inch alloys from Kalimnos as part of the Black upgrade.  In addition, front and back spoilers, and boot lid finisher are also body colour.  Sadly, only three collors are available when buying both Speed and Black kits: Polaris White, Salsa Red, and Ultimate Black.  XKR Side Graphics may also be applied.  Inside, Charcoal-colored leather in several grains with a choice of contrast stitching is also included.  Dark Mesh Aluminum, Dark Oak, and Piano Black are the available trims.

Starting price of the Jaguar XKR Coupe is £74,955.  The car with the Speed and Black Packs will be shown off at Geneva next month.
