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 XE SV Project 8 takes Laguna Seca production sedan record

Jaguar has claimed another Laguna Seca record with Randy Pobst at the wheel. This time around, the Jaguar XE SV Project 8 became the fastest four-door sedan to lap the track, with a time of 1 minute, 37.54 seconds. The record follows the production electric car record set in late August with an unmodified I-Pace HSE, and it's also the fastest recorded Jaguar time on the track; the previous fastest Jaguar there was the 575-horsepower F-Type SVR. As it seems most Laguna Seca records have been set by Pobst, the previous four-door production sedan record was also his handiwork, in a Cadillac CTS-V. That time was about a second slower than the XE SV Project 8, at 1 minute, 38.52. The fastest Pobst time at Laguna Seca stands at 1:28.65, driven with a Dodge Viper ACR MkV. The Laguna Seca record isn't the first lap record claimed by the XE SV Project 8, as it took the production sedan honors at the Nurburgring Nordschleife in November 2017, with a time of 7 minutes, 21.23 seconds. Only 300 vehicles will be built, at the JLR Special Vehicle Operations facility in Coventry, England. The XE SV Project 8 hits 60 mph in just 3.3 seconds, thanks to its 591-horsepower, supercharged V8 engine, which propels it all the way to 200 mph. There are two versions available, a more road-suitable four-seater and a special Track Pack car with lightweight carbon fiber racing seats.Related Video:

This Jaguar E-Type is an even longer-legged feline

Paul Branstad loves the shape and purity of the Series 1 Jaguar E-Type, produced from 1961 to 1968, but appreciates the longer length of the Series 3 V12 model, which affords occupants a more comfortable space in which to enjoy long trips. So when Branstad brought his damaged left-hand-drive 1968 roadster from its home in the US to Classic Motor Cars in the UK for a restoration, he had a special request: restore his car, but make it a bit longer.
"This is something that we have never done before. Our client wanted the interior leg room of a Series 3 V12 E-Type but the aesthetics of a Series 1 car," says Nick Goldthorp, managing director of CMC.
For the restoration, CMC added 4.5 inches of length to the floor pan of Branstad's E-Type to create the extra legroom. Goldthorp relates, "The V12 was actually nine inches longer than a Series 1 but a lot of the additional room was behind the seats as storage and was not required on our project." That's because CMC also built a trailer out of two E-Type rear ends that attaches to a custom-made removable tow hitch.
