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.

Top Gear season 25 opens with a V8 roadtrip through America

Great news for fans of BBC Top Gear: the first episode of season 25 is here. Viewers of BBC America will catch the season opener on March 3, and for the American audience this episode is definitely suitable watching. The episode has been dedicated to V8 sportscars almost in its entirety, as it's been wrapped around a Western roadtrip with a motorsport bias. The three hosts get to choose three V8 sports cars, with the basic idea of finding the best all-rounder. Matt LeBlanc goes for a Hennessey-tuned GT350R, Rory Reid chooses a Jaguar F-Type SVR, and Chris Harris shakes up the pack by selecting a McLaren 570GT. It's a nicely varied trio, with V8 power still showing what it's good for. There are various challenges along the way, just like there should be on a Top Gear roadtrip episode – even if the road surface itself isn't always ideal. But things smoothen out, all the way to a NASCAR oval and an airport runway; the flooded Bonneville salt flats aren't suitable for shenanigans, so substitutes have to be found. The trio also hit dirt roads, and have to evade a buggy-driving Ken Block during a "moonshine run to the border." Fans of Sabine Schmitz will be pleased to find her piloting a chain car racer, which consists of two American junk cars with a Honda CRX chained in the middle. It must make sense to someone. The Star In A Reasonably Priced Car segment has been retained for this season. This time it's the British actor Rob Brydon driving the Toyota GT86, on a very wet lap around the show's Dunsfold Aerodrome track that must be a cult classic by now. All in all, the season 25 opener is exactly what it says on the tin. There's nothing out of the ordinary, but it still has excellent cinematography, V8 roar and some nice landscapes. Classic Top Gear. Cowboy duels, Sabine Schmitz chain car racing, @RobBrydon, a @kblock43 car chase and #TheStig The latest episode of #TopGear is available on @BBCiPlayer now. Outside the UK?

Jaguar Land Rover puts the freeze on wounded soldier-athletes [w/video]

For athletes, the cold is often a powerful ally in treating injures, with RICE (rest, ice, compression and elevation) a popular means of treating muscle pulls, bruising and other common forms of discomfort. Did you know, though, that frosty temps are also popular tools for simply recovering from a rough training session?
Well, we're guessing Jaguar Land Rover knew that, as the British company was kind enough to loan out its climactic testing chamber to Jaco van Gass and Luke Darlington, a pair of veterans wounded in their service to Queen and Country. Van Gass, a former private in the Royal Army, and Darlington, a Royal Marine, are attempting to earn a spot on the British Armed Forces cycling team for the upcoming Invictus Games.
The Games, inspired by the Warrior Games held in the United States, are a sporting competition reserved for injured servicemen and women, either active duty or veterans, and is slated to take place from September 10 to 14 in London's former Olympic venues. Van Gass lost his left arm below the elbow after getting hit by a rocket-propelled grenade (he also suffered from a collapsed lung, punctured internal organs, severe shrapnel and blast wounds, a broken tibia and a fractured knee). Darlington, meanwhile, suffered a traumatic brain injury during action in Afghanistan, and he now suffers from weakness in his right side and cognitive issues.
