Jaguar XJ220 owners: you can now buy replacement tyres for your supercar

Produced from 1992–1994, the Jaguar XJ220 has gone a long time without new rubber — but that is set to change thanks to Bridgestone.

When you look at the Jaguar XJ220 it’s easily identified as a ’90s supercar. Its wheels are too small, it lacks modern aero, and it has an interior almost pinched from a 1991 Mitsubishi GTO. The ’90s were a long time ago, and so was the last time Jaguar XJ220 owners have been able to buy replacement tyres. A scary thought considering the XJ220 is capable of reaching 349.4kph — and it held the Guinness Book of Records fastest speed ever attained by a standard production car from 1994 to 1999. 

Just recently though, Bridgestone announced that they have teamed up with Don Law of Don Law Racing to develop a new OEM-spec tyre for the XJ220. Something as simple as a tyre has no doubt hurt resale value of the iconic ’90s machine, so it’ll be interesting to watch the prices skyrocket once people start getting them out of their storage holds. The new Bridgestone tyre is said to greatly outperform the original due to the advancements in tyre technology, which will be exciting to see, and they’ll be ready for the car’s 25th anniversary in 2017. If you’re curious about just how big the tyres are, try 255/55R17 tyres up front and 345/35R18 tyres down the back — just bonkers. That’s 300mm short of one metre of rubber touching the ground, just on the back! 

The XJ220 was an interesting beast. Originally it was meant to be a V12 all-wheel drive, and after taking 1500 £50,000 deposits Jaguar changed their mind, dropped two driving wheels, halved the amount of pistons and added two turbochargers — weird right? This came at a time when only Japan was producing such vehicles, as European supercars were meant to be V8, V10, or V12, and, more importantly, naturally aspirated. 

Jeremy Clarkson once described the turbocharger lag of the XJ220 to be terrible, and demonstrated by putting his foot down and counting until the boost came in. When it did come in it was quick, and produced 400kW (550hp) and 644Nm (475lb-ft) of torque. The XJ220 would accelerate to 100kph in only 3.6 seconds, which even by today’s standards is seriously moving. The 3.5-litre V6 engine found in the production XJ220 was dry-sumped, had Zytek multi-point injection with dual injectors and Zytek electronic engine management — all way ahead of its time. The engine block was produced from aluminium, as were the heads. An interesting note is that the XJ220 would receive 8.8L/100kms, which matches most common commuter cars of today. Not surprising though when you think how bad the turbocharger lag was — it was probably never on boost! 

Merry Christmas from NZ Classic Car magazine

The Classic Car magazine team is taking a few weeks’ holiday from the work computer and heading to the beach for some kickback time.
Merry Christmas, and have a wonderful summer holiday to all our readers, followers, and fans. Enjoy this special extra time with the family. We will be posting archive articles again in mid to late January.
Have fun, be good and be careful out there.

Two engines instead of one?

Popping two motors into a car is not only complicated, it doesn’t always end well. Donn Anderson recalls early attempts, including John Cooper’s ill-fated original Twini Mini built 58 years ago

For a boost in performance, better traction, and perhaps improved handling to some, two motors seems an obvious solution. It would also eliminate the need to develop a larger engine replacement from scratch, but would that outweigh the not inconsiderable technical difficulties?
The idea of using a pair of engines dates back at least 86 years to the Alfa Romeo Bimotor single seater racing car that was officially timed at 335km/h, or 208mph. Taking a lengthened Alfa P3 chassis, the Italians fitted two supercharged straight eight 2.9-litre and 3.2-litre engines, one in front of the cockpit, and the other behind the cockpit.
