Jay Leno hits the road in a 1951 Jaguar XK 120 Hot Rod

The 1951 Jaguar XK120 featured in this episode of Jay Leno's Garage might look vaguely like a classic Jag roadster at first, but underneath this cat is something completely different. It was built by Leno's buddy Jason Len of XK's Unlimited when he grew tired of keeping these convertibles stock, and this aluminum-bodied beast was the result. Practically the only major Jaguar part left is the engine. It's a tuned 3.8-liter inline six from an E-Type with Weber carbs that makes an estimated 300 horsepower out of some gorgeous side-exit exhausts. The mill is backed up to a BorgWarner five-speed manual. However, the big surprise is the chassis. In place of Jag's original solution, Len has a custom tubular space frame that he claims sheds some 1,000 pounds over the stock example. There are still some classic Jaguar touches left, though, such as the fin over the driver's head that is reminiscent of the D-Type, and both the wheels and gauges are replicas based on that classic racer. Of course the best part is watching Jay drive this Jag hot rod. This big cat really knows how to purr.

Jaguar I-Pace EV will finally be revealed, available to order March 1

It sure feels like the Jaguar I-Pace electric car concept was revealed longer ago than November 2016. That might be because in addition to running barely camouflaged production models around for months, the company has even announced a one-make race series with the car before we've seen the revealed production model. But the wait is almost over. The company finally announced a reveal date of March 1. This comes just before the Geneva Motor Show, and the debut will be shown on a livestream. Not only that, but Jaguar will be taking orders for the EV the same day. Reveal and order dates weren't the only things Jaguar announced regarding the I-Pace. The company also said the I-Pace will be able to get an 80 percent charge from a DC fast charger in just 45 minutes. This charge time necessitates a 100-kW fast charger, though, so that time may vary in real life based on what chargers are available. This is also greater charging capability than Jaguar claimed when the concept was revealed, which promised an 80 percent charge in two hours on a 50-kW fast charger. Jaguar hasn't revealed many other details about the production car yet. When the concept was shown, Jaguar claimed it made 400 horsepower and had a range of 220 miles. The prototypes we've seen on the road also look extremely similar to the concept, so there shouldn't be much, if any, disappointment in the styling department when it's revealed. Related Video:

Jaguar Land Rover offers (some) detail about new Ingenium engine

Jaguar Land Rover officially announced its Ingenium family of engines with the unveiling of the 2.0-liter version in the Jaguar XE concept at the 2014 Geneva Motor Show, but it kept details very thin at the time. All we knew was that the new turbocharged mills could be configured to use gasoline or diesel, and be positioned longitudinally or transversely. Months later, JLR is finally letting some more info slip about its new baby, but there are still some big questions to be answered.
For the Ingenium project, Jaguar Land Rover gave its engineers a clean sheet of paper and told them not to worry about using any previous parts or machinery. In the end, the designers came up with a family of turbocharged, aluminum-block engines based around modular, 500cc cylinders to allow it to grow or shrink as the market demanded. The layout was also made adaptable enough to incorporate hybrid drivetrains, if needed. "Being configurable and flexible are the two key strands of Ingenium's DNA because we have future-proofed our new engines from the outset," said said Ron Lee, the company's director of Powertrain Engineering.
To maximize efficiency, Jaguar promises that all versions of the Ingenium engines come with computer-controlled, variable oil pumps and water pumps to use only as much energy as needed. They also get direct injection, roller bearings for the cams and stop/start. The diesel version alone has 17 percent less internal friction than the mill it replaces, the company claims. JLR is also promising class-leading figures for Ingenium's torque and horsepower too, but it's not giving away those specs just yet.
