Junkyard Gem: 1973 Jaguar XJ6

It requires a certain high level of commitment to keep an old Jaguar on the road, and so plenty of first-generation Jaguar XJs end up as projects that never get finished, sitting in yards or garages for decades before winding up in the nearest U-Wrench yard. As I clomp through car graveyards around the country in search of interesting machinery, I see so many 1980s XJs that I don't bother to photograph many of them … but a genuine Series I early Jag is a different story. Here's a '73 XJ6 whose final parking space (prior to facing the cold steel jaws of The Crusher) sits right next to that of a same-year Mercedes-Benz 450SLC in an East Bay yard. How the mighty have fallen! The C107 was too picked-over to be worth photographing, but you can admire the photos of this much nicer '72 I found in Denver a few years back. Unlike the last Series 1 XJ6 that I've photographed (in the very same yard, albeit 13 years ago), this car has not had its original straight-six engine replaced by a small-block Chevrolet V8 (because Jaguar parts were expensive and Chevy parts were cheap during the 1970s, that swap happened frequently). The US-market XJ6 got 150 horsepower from this smooth-running DOHC six, 40 fewer horses than the (far more expensive) 450SLC that year. The interior looks ravaged by the decades, but you can still discern the opulence that once reigned in this wood-and-leather-lined space. The dash boasts a full complement of authentic Smiths gauges, with a tasteful Kienzle clock right in the middle. Here's why we can assume that fewer than two of those instruments functioned at any given time during the life of this car: wiring by The Prince of Darkness! Working on electrical faults in these cars built up your patience while undermining your faith in symptom-to-problem relationships. The six-digit odometer ensures that we'll never know if we're looking at a 56,819-mile car or a 356,819-mile car. I'd guess 156,819 if I had to, based on pedal wear. These cars were very popular in the Bay Area, which has been full of European-car aficionados since the first Renault AXs sputtered off the docks of the San Francisco waterfront. Back in the 1970s and 1980s, you'd never see an old XJ without one of these pre-EU "GB" stickers on the back. The faded condition of this one suggests decades of sitting in the sun, probably while the car sat dead in the driveway due to electrical problems.

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.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.
