This classic Jaguar XJ has a 720-hp ungentlemanly secret

Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.

Jaguar F-Type Coupe is here, will debut on stage in LA

When Jaguar previewed its new sportscar two years ago with the C-X16 concept, it showed a coupe form. But when the car hit production as the F-Type, it rolled out in roadster form only. Not that we're complaining, but we all knew it wouldn't be long before Coventry revealed the production coupe, and that's just what it's doing at this month's LA Auto Show.
Jaguar hasn't given us much to go on yet - just a single shot of the vehicle from above and nothing in the way of technical details - but we all know the drill. The F-Type Coupe will essentially be the same as the existing roadster, only with a fixed roof - with a large glass panel, mind you, to let plenty of light in and keep the cabin from feeling markedly more claustrophobic than the open-top version.
That ought to make it a little lighter (though not much) and a little stiffer, but otherwise we can expect more or less the same specs as the convertible. We'll have to wait until the evening of November 19 to know for sure, though, so watch this space for more.

Jaguar's electric speedboat smashes decade-old record

We knew Jaguars prowl on dry land, but apparently they dabble with water, too. Jaguar teamed up with powerboat racing specialist Vector and Williams Advanced Engineering to beat the existing British and world records for fastest battery-powered boat with some expertise from Jaguar's Formula E team. The team had to top 76.8 mph, a record set in 2008 by Helen Loney in her Firefly electric hydroplane with Agni motors. The attempt was made in the same location, Coniston Water in the English Lake District, where speedboat record runs have been made since the days of Sir Malcolm Campbell as early as the 1930s, and son Sir Donald Campbell into the 1950s and 1960s – including the fateful record attempt that cost the younger Campbell his life in 1967. The company's documented the attempt in the video shown above. It reveals that the 2008 record wasn't easy to beat. At first, pilot and Jaguar Vector co-founder Peter Dredge managed to get the boat to 76.6 mph – annoyingly close to, and just under, the record. But a later run rewarded the team's efforts, with a clear improvement of nearly 12 mph, making the new record 88.61 miles per hour. This achievement is also impressive considering that Jaguar and Vector only announced their partnership in October 2017, so progress has been swift. The tech in the boat is reportedly derived from Formula E technology, though Jaguar Vector and Williams Advanced Engineering have not disclosed the boat's exact specifications nor what parts are based on Jaguar Formula E car parts.
