Fastest Jaguar ever XFR

Back in the early 90s, the Jaguar XJ220 was considered a supercar. It’s 500 hp engine made it the fastest Jaguar ever produced with a 1992 top speed run of 217.1 mph. Now flash foward 17 years later where that record gets shattered by a sedan. Jag took its new XFR to the Bonneville Salt Flats to record a top speed of 225.675mph.

The new XFR is powered by a 5.0-litre V8 engine developing 510 hp and 625Nm of torque. But Jaguar did admit that the record setting car had minor aerodynamic and safety modifications to meet the requirements for a Bonneville run, as well as additional horsepower was “liberated” by a remapped ECU, a modified air intake, modified exhaust, and revised supercharger settings. Still, no internal engine components were changed and the six-speed automatic transmission was standard, including the gear ratios.

But don’t despair, the factory-fresh version should be no slouch either. It makes the 0 to 60 mph sprint in 4.7 seconds, but that car will hit an electronic limiter at 155 mph.

World fastest electric car

We like stuff that comes from Shelby SuperCars (SSC) because its fast. The Ultimate Aero currently holds the record for world’s fastest production car at 256 mph, and the 2009 car is promised to be even faster. So when SSC announced it will build the world’s fastest electric car last summer, we thought we might have a reason to start getting excited about EV cars (no offense Tesla).

SSC decided to release a few details about its progress on the electric supercar, and its having us check the calendar to make sure it isn’t April Fool’s Day. For starters, SSC is keeping with its basic principle and keeping the electric car’s charge time fast; a hard to believe ten minutes.

In a sixth of an hour, SSC says its Nanotechnology Rechargeable Lithium Battery pack can be charged up for a 200 mile run. These figures are not from hooking up the car directly to the local nuclear power plant, but just by using the same household plug that powers an alarm clock. The reason why his is a little questionable is because the engineering team at SSC has accomplished what a lot of bigger companies have not been able to do yet. For example Chevrolet’s Volt will need an eight hour charge on a 110v plug to go 40 miles.

If SSC really has created a system the will charge an EV car’s batteries in the same time it takes to fill up with fuel, and it fits in a performance car, then the electric car revolution may really be here. Now all we have to do is keep our homes from burning down when the Ultimate Aero EV pulls the current (presumably an ungodly amount) to get its quick charge.
