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 axes supercar plans, focuses on luxury EVs

Jaguar is abandoning plans to replace the XK coupe and convertible and won't build a production variant of the C-X75 supercar, according to Automobile Magazine. Previous reports indicated that Jaguar could revive the XK line as a grand tourer, but the automaker has turned toward building two electric vehicles (EV). One would be a replacement for the XJ sedan and the other a premium SUV. The large luxury EV, codenamed X590, is reported to be a four-door coupe with a rear hatch that signifies a drastic shift in strategy by Jaguar. The vehicle is said to be a compromise between Jaguar Land Rover CEO Ralf Speth and Jaguar design chief Ian Callum. According to the report, the X590 will utilize a new electronic architecture that can be adapted to accommodate the software for autonomous driving capability that was developed under former BMW engineer Wolfgang Ziebart. Jaguar looks to take on the Tesla Model S and the slew of electric vehicles from Germany with the X590. While Jaguar hopes the EV will allow the automaker to expand to a new segment, it will continue to sell the current XJ alongside the X590. Meanwhile, an unnamed source claims Jaguar will put an electric SUV on the road shortly after the X590 in 2019. Originally planned as a Range Rover, the ute is reported to have a modern look with a focus on aerodynamics. The SUV will be offered as a rear-wheel-drive model with one motor or an all-wheel-drive version with two motors. Both variants will have a choice of three battery packs based on range, performance, and charge time. Jaguar expects to put 20,000 to 30,000 units of the X590 on the road every year, while the SUV, which should be more affordable, will have a production rate between 30,000 and 50,000 units. With the electric and SUV segment continuing to grow, Jaguar is looking to capitalize with two new vehicles that could set the tone for its future. Related Video:
