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.

2014 Jaguar F-Type, Project 7 Concept snarl in Jay Leno's Garage

Jay Leno gets to drive a lot of nice cars, and the Jaguar F-Type V8 S he pilots in the latest episode of Jay Leno's Garage is no exception. Eric Johnson, vice president of Jaguar Western Region brought the car to Leno's garage, which impresses the comedian with its 5.0-liter V8 that makes 495 horsepower, 460 pound-feet of torque and a muscle car-like roar.
But there's a surprise this episode: Leno secured a drive in the Project 7 Concept at Pebble Beach this year, and the experience was caught on video. Based on the F-Type, the Project 7 is a functional concept car that nods to Jaguar's seven wins at Le Mans and features bespoke styling cues, a special exhaust system and, perhaps most importantly, 50 more horsepower from the supercharged V8.
Watch the latest episode of Jay Leno's Garage in the video below. You'll need a little over 23 minutes to see the whole thing.

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.
