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.

Lunaz electrifying classic cars with coachbuilt, millimeter precision

One day last year, as David Lorenz waited by the side of the road for repair help with his classic car, he had an idea: Why not update all of that ancient mechanical "character" with a modern electric drivetrain? That would give an owner the beauty of the past, the mechanicals of the present, and the powertrain of the future. Jaguar does it with the E-Type Zero, and Aston Martin's in the game with the reversible EV powertrain swap for the DB6 Volante. And so Lorenz founded the British engineering firm Lunaz Design, named after his daughter Luna and headquartered at the Silverstone Technology Park. The company's first products are almost ready for order, starting with a 1953 Jaguar XK120 and a 1961 Rolls-Royce Phantom V. Lunaz conversions aren't a matter of pulling an engine and installing a battery pack; Lunaz reengineers classics. Managing Director Jon Hilton oversees a team bringing experience from carmakers such as Aston Martin, Ferrari, Jaguar, McLaren, and Rolls-Royce, with Hilton's resume including six years with Cosworth Engineering followed by eight years in Formula One. To develop the Lunaz offerings, a chosen car is stripped to the metal and weighed so that engineers understand the weight distribution at each corner, then the car is stripped to the chassis and 3D-scanned. This yields information allowing designers to create a powertrain that fits to the millimeter and stays true to the handling dynamics of the original vehicle. During the rebuild, the company says, any imperfections are remedied "using traditional coachbuilding techniques." The Jaguar and the Rolls-Royce get battery packs in two locations, one under the hood and one under the trunk floor. Lunaz says it can fit more battery for its in-house design into each car that way. The Jaguar's 80-kWh battery feeds two electric motors sending 375 horsepower and 516 pound-feet of torque to the rear wheels. The Phantom V uses a 120-kWh battery pack, but its output hasn't been released. While remaining true to the exterior and interior design of each car, Lunaz fits LED lights and modern tires, a modern suspension, better brakes with regenerative braking, power steering, an upgraded propshaft, and a fly-by-wire throttle. Safety and comfort additions include cruise control, traction control, and anti-lock brakes. Inside, the instrument cluster gets battery gauges, there's modern climate control, an infotainment screen with satellite navigation, and a Wi-Fi hotspot.

Jaguar might not sell many XF Sportbrakes in the U.S., but here's why it's trying

One of the wonderful surprises of this year was when we learned that the U.S. would receive the XF Sportbrake wagon, and — less of a surprise — it's as much a looker as the previous generation. And while we're never one to look a gift car in the grille, it did seem strange that Jaguar would attempt to bring a wagon to the U.S., especially when it already had a similarly sized F-Pace crossover. So we spoke with Jaguar CEO Joe Eberhardt, Jaguar Design Director Ian Callum, and Jaguar's head of product planning in the U.S. to find out what prompted the company to bring the XF Sportbrake here. There were a few key reasons. One was simply that the folks at Jaguar really like the car, and they know that journalists like wagons. That doesn't exactly pay the bills for a car, but the enthusiasm is good. According to these people at Jaguar, though, they do believe there is a market for the car, and they expect to sell most of them on the coasts. Obviously, even if Jaguar sees a wagon market, it's still going to be much smaller than for crossover SUVs. But no matter how small that market is, Jaguar has an extra advantage for bringing the wagon here. The company knew it was going to make a wagon regardless of whether it would come to America, since the wagon market in Europe is so strong. In fact, Jaguar expects that half of XF sales in Europe will be Sportbrakes. So the majority of the engineering costs will be covered from those sales. The folks at Jaguar also told us that the car wasn't difficult to homologate for the U.S., so the cost of bringing it here was minimal. So in the worst case scenario that has the XF Sportbrake hardly selling in America, Jaguar isn't going to be seriously hurt. And if it's a success, then it's even more of a success. So the XF Sportbrake isn't purely a passion product, but that's OK. It means consumers have one more option to the multitude of crossovers in the U.S., and enthusiasts have the chance to own a super cool wagon. Also, although the XF Sportbrake is currently only available in America in top-level 380-horsepower S trim, Jaguar said lower trim levels and lower-output engines, all at lower prices, will be available here in the coming year or so. Meaning there will be even more ways to satisfy your wagon itch. Related Video:
