Jaguar is introducing two optional packages for its flagship XJ. The normal models get the Sport pack, while the supercharged versions gets the Speed pack.

Ingredients of the Sport pack are a number of exterior and interior design options, including a subtle body kit with add-on parts for front and rear, new 20-inch alloy wheel design, red brake callipers, optional sports seating for front and rear passengers, and additional interior trim choices mean even greater colour and veneer combinations.

The Sport Pack is available on nearly all engine variants, including the muscular twin-turbo diesel, market-specific 3.0 V6 petrol and naturally-aspirated 5.0-litre AJ-V8 where it serves to emphasise the sporting character and driver involvement that are core strengths of every XJ model.

The Speed pack, exclusive to supercharged models with exterior Sport Pack, only raises the electronically limited maximum speed from 155mph (250km/h) to 174mph (280km/h). So it makes more sense to buy the supercharged XJ now!
