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.

Jaguar Vision Gran Turismo SV ups the performance of the virtual sports car

Last year, Jaguar created its very first concept car made specifically for the Gran Turismo video game series, and this year it's following it up with an even faster racing variant. It's called the Jaguar Vision Gran Turismo SV, and it has some pretty wild specifications. This virtual racing machine no longer uses three motors, but four, with the extra motor being fitted to the front and allowing torque vectoring at all four wheels. Output has increased substantially to 1,877 horsepower and 2,478 pound-feet of torque. The regular Jaguar Vision Gran Turismo "only" made 1,005 horsepower and 885 pound-feet of torque. Jaguar claims a 0-60 mph time for the SV of 1.65 seconds and a top speed of 255 mph. That top speed might be higher if it weren't for the various aerodynamic aids adding downforce. It has a huge splitter, diffuser and long adaptive rear wing. The car can create up to 1,000 pounds of downforce at 200 mph. One other wild performance feature is the cooling system for the lithium-ion battery pack. It has a coolant circuit with liquid nitrogen that ensures the battery doesn't overheat when discharging the massive amount of electricity to run the powerful motors. Though Jaguar will likely never actually produce a functional version of this car in real life, the company did at least create a full-size model of it. It should be impressive in person given its extraordinarily low, wide and long shape. We're hoping it shows up at car shows when the pandemic subsides. The virtual car is due to be available in 2021. Jaguar didn't specifically say which version of Gran Turismo is will be featured in. The regular car can be driven in "Gran Turismo Sport." The racing version could be added to "Gran Turismo Sport," but the launch date of 2021 has us wondering if it will instead show up in "Gran Turismo 7" for PlayStation 5. Related Video:

Reliving the Jaguar XJ220 with a father-son duo

Jaguar may have canceled the C-X75 project, but there was a time when the Leaping Cat marque did make supercars. Sure, there were the XJR-9 and XJR-15 homologation specials made by TWR, but more famous was the XJ220. Although its reign may have lasted only a year before the McLaren F1 came along, for a brief time in the early 1990s, the XJ220 was the fastest car in the world – which is even more impressive when you consider that it was only powered by a 3.5-liter twin-turbo V6 when its rivals were using mostly V8s and V12s. That makes the XJ220 a rather noteworthy supercar from the dawn of the 200-mph era. The thing is, while Jaguar has come to embrace the XJ220 as an exceptional part of its history, it doesn't have the time or energy to devote to servicing the 275 that were made between 1992 and 1994. So it turns to Don Law Racing. The father-son team – made up of a master mechanic and his hot-shoe offspring – is tasked with keeping the XJ220 alive both in body and in spirit, and do so with a great deal of well-deserved pride. Drive went out to their workshop in Staffordshire to tell their story.
