The story behind Bridgestone's new tires for the rare and beautiful Jaguar XJ220

The Jaguar XJ220 is a beautiful, fast, and arguably under appreciated supercar from the early 1990s. While contemporaries like the Ferrari F40 and Porsche 959 garner more than $1 million at auctions, the XJ220 might pull in half that. Maintaining an older car requires work, a task made more difficult when parts aren't available. Last year, Bridgestone announced it was producing new tires specifically for XJ220s. The Japanese tire supplier has released a 42-minute video documenting the process. There were only 275 XJ220s ever built, fewer than both the F40 and 959. Until recently, no supplier made four same-spec tires that would fit the XJ220. Early Dodge Viper owners suffer from the same problem. Thanks to both Bridgestone and Pirelli, owners now have two options to choose from. Bridgestone worked with Don Law Racing, the go-to shop for all things XJ220, when developing the right tire for the car. It isn't simply a reproduction of an older-spec tire. Bridgestone tested a number of new compounds. With so few cars available, from the beginning this was going to be a money-losing prospect for the tire maker. Enthusiasts within the organization fought hard to get everything approved. Watch the full video to hear how much time and effort went into the project.

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.

The first Jaguar Project 7 is the new kid in Harry's Garage

The Jaguar Project 7 is more than just an F-Type with a dab more power and a special body, and Harry Metcalfe (who advises Jaguar Land Rover Special Vehicle Operations, which built the car) is here to show us why. This limited-production model is something truly special, and despite Metcalfe's role with JLR it's hard to misinterpret the enjoyment in his eyes when the supercharged V8 roars. Metcalfe's Project 7 is number one of just 250 cars built and wears a British Racing Green body with orange accents around the nose, mirrors, brake calipers, and underneath the rear spoiler – classic sports car style with a little modern flash. His example is also special because the entire build team signed the area underneath the trunk lid. While the engine comes up to temperature during his drive, Metcalfe shows that the Project 7 can be a fine grand tourer, and he eventually puts the throttle down to let his audience here the sublime engine. Metcalfe claims the limited edition Jag actually has too much horsepower but he means that in the best way possible. Driving it reminds him of being behind the wheel of his Pagani Zonda – a fine compliment for a grand tourer to be compared to an ultra-exotic supercar Find out why by taking a ride with Harry.
