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.

2021 Jaguar F-Type R Exhaust Test | Music to a gearhead's ears

Against all odds, England has outmaneuvered America for the most savage and wicked-sounding V8 among the two countries. The 5.0-liter supercharged V8 in the Jaguar F-Type has sounded better than anything since it was popped into the R and SVR. Sorry Hellcats, Coyotes, and small blocks everywhere. Jaguar wins. Ford’s flat-plane crank Voodoo V8 in the GT350 and GT350R might be the only one that can compete on the same playing field. One drive in the 2021 Jaguar F-Type R will have you asking, how is this legal? The sheer level of noise coming out of those four very real chrome exhaust tips ensures every single head turns towards the Jaguar sports car if it hadnÂ’t already. In fact, itÂ’s so loud that we even struggled to record it authentically. You see, flooring it all but overwhelmed our microphone with the deafening roar. The key to hearing what the actual exhaust note sounds like is listening to it rev at a slower rate of speed. Then thereÂ’s the trouble of picking up its glorious overrun full of racecar-like yowls and crackling for days. No matter how you drive, youÂ’re guaranteed to be the most obnoxious individual around. Revving it up to around 3,500 rpm in first gear then releasing the throttle unloads a scary level of pops and crackles that echo throughout entire downtown blocks. ItÂ’s almost like Jaguar figured people would still want to make a stupid amount of noise even if theyÂ’re driving along slowly. This car has no chill. Pulling an upshift anywhere past 4,000 rpm prompts a chainsaw-like, ripping braaaaap that will scare small children and the easily-startled everywhere. It induces endless laughter and enjoyment for the driver behind the wheel. The cliche of "itÂ’ll bring out your inner child" perfectly applies to the F-Type R.  Americans can rest assured that theyÂ’re getting the most savage version of JaguarÂ’s exhaust, too. European F-Types have the required gasoline particulate filters that choke the noise, whereas U.S. cars donÂ’t. Sorry, Earth. If youÂ’ve done much reading on the 2021 F-Type already, youÂ’d know that this updated R actually gets the same engine as the previous generationÂ’s SVR. That means it has 575 horsepower and 516 pound-feet of torque. However, the exhaust on the new R is different from the old SVR in that itÂ’s slightly tamer. ItÂ’s difficult to fathom a wilder exhaust than the one fitted to this R, but it makes perfect sense to reserve the ultimate noise maker for the ultimate version of the F-Type.

Jaguar Classic heading to Le Mans with vintage racers

A grid full of vintage Jaguars will rumble into France in July to race in the Jaguar Classic Challenge during the Le Mans Classic. The event should give motorsport fans plenty to watch with a bevy of pre-1966 Jags on the famous circuit, including E-Types, XKs, C-Types, D-Types, and even the company's sedans. Jaguar launched the vintage racing series last year to build on the success of the popular E-type Challenge. It continues with a five-event calendar this season but swaps out a meeting at Brands Hatch to go to Le Mans – hard to argue with that change. The drivers also get to lap Donington Park, Silverstone, the Nurburgring, and Oulton Park. Le Mans is practically a home track for these classic Jags. The British automaker dominated the 24-hour race there in the 1950s, including overall victories in '51, '53, '55, '56, and '57. "Watching a diverse array of pre-1966 Jaguars racing on the iconic circuit, some of which even raced there in period, will surely be a sight not to be missed," Tim Hannig, Jaguar Land Rover Classic Director, said in the season announcement. Again, we find it hard to argue with that sentiment.

The Le Mans Classic will be one of the major highlights of the forthcoming season that will see a diverse field of pre-1966 Jaguars going wheel-to-wheel in the competitive single-marque series. Jaguar has a long and successful history at Le Mans, with the marque first winning there back in 1951 with Peter Walker and Peter Whitehead driving the C-type - affectionately known as XKC 003. A one-two finish followed this in 1953 with the duo of Tony Rolt and Duncan Hamilton taking overall honours. Jaguar dominated Le Mans for three consecutive years in 1955, 1956 and 1957 in the D-type.
