Petrolicious examines a very special Jaguar C-Type

There are rare Jaguars, and then there's this stunning C-Type Lightweight Le Mans. Built in response to the dominance of the Mercedes-Benz 300SL at the 1952 24 Hours of Le Mans, Jaguar made only three C-Types for 1953 and managed to capture first, second, and fourth. These cars featured four-wheel disc brakes – a rarity at the time even in endurance racing – and a lighter aluminum body. The two SU carburetors were swapped out for three Webers, meaning more power and, according to RM Sotheby's David Swig, better throttle response. Swig would know. In the latest video from Petrolicious, he takes the fourth-place C-Type for a ride, giving us a look at the sleek open-roof racer in action, while our ears enjoy the delicious sound of the 3.4-liter, twin-cam straight-six. "What I love about these cars is how communicative they are on the road," Swig told Petrolicious. "How when you're going through a corner, you feel in the seat of your pants and through the steering wheel every little movement, every little pebble that you drive over." Beyond the driving experience, there's something to be said of the historical seat Swig is occupying. "No less than five Le Mans-winning drivers of this period have sat behind the wheel of this car," Swig said, "which almost give you goosebumps." Should you have the money, you can actually put this iconic racing Jaguar in your garage. RM Sotheby's will offer it for auction as part of its glitzy Monterey Car Week event next month. While you can look forward to our coverage of that event come August, you can enjoy the sight and sound of this iconic C-Type in the latest episode from Petrolicious.

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.

1955 Jaguar D-Type that won Le Mans sets $21.78 million record price at auction

There's simply no denying that the Jaguar D-Type is one of the most noteworthy race cars ever devised. Jaguar pioneered the use of the monocoque chassis design, and D-Types won the 24 Hours of Le Mans in 1955, 1956, and 1957. And with its bodywork pulled taught over the wheels, engine, and passenger compartment, not to mention the massive fin behind the driver's headrest, the D-Type also one of the most stunning. The car you see above, Jaguar D-Type chassis number XKD 501, won the 24 Hours of Le Mans in 1956, narrowly defeating a team from Aston Martin. Along the way, this D-Type completed 2,507.19 miles at an average speed of 104.47 miles per hour, and a maximum speed of 156.868 mph on the Mulsanne Straight. It was entered by the non-factory team Ecurie Ecosse, and therefore painted in the team's traditional Scottish blue with a white cross. That kind of provenance, coupled with its pristine original race-winning condition, makes XKD 501 extremely valuable. In fact, it just sold at RM Sotheby's Monterey auction for $21.78 million (a $19.8 million bid plus auction fees), making it the most expensive British automobile ever sold at auction. Take a gander at our high-res image gallery above to soak up all its low-slung goodness. Related Video:
