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.

Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.

Watch a Jaguar F-Type R drag a parachute at 186 mph

With carbon-ceramic brakes on offer, the Jaguar F-Type R Coupe can shed off speed even faster than it can rack it up. Even the standard steel rotors do a pretty good job of it. But what would happen if you deployed a parachute out the back of the Jag at 186 miles per hour, like you might with a drag racer? That's what the British automaker has found out in this latest video. And just why would they do such a thing, you ask? Because Bloodhound, that's why. Jaguar is providing technical support to the Bloodhound SSC land speed record attempt, and one of the roles into which the F-Type has been pressed is to check the parachute that will (along with the air brakes and rotors) form an integral part of the jet- and rocket-powered vehicle's run. To make sure the chute would do its job, the team put Royal Air Force pilot Andy Green behind the wheel of the specially equipped F-Type at the RAF air base in Bentwaters, Suffolk, UK, had him speed down the runway up to the car's top speed and deploy the chute. Fortunately, as you can see from the minute-long clip, everything seemed to have gone according to plan – though we're not sure about the logic behind the assertion that if "it worked at 180, it will definitely work at a thousand miles an hour."

The jet and rocket powered car, which aims to surpass the current record of 763.035mph before targeting 1000mph, has multiple braking systems including air-brakes ('doors' mounted on the side of the car which open to increase aerodynamic drag) and disc brakes (used when slowing down from 200mph).
