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.

Autocar compares new Maserati Quattroporte to Jaguar XJ

Autocar's Steve Sutcliffe took the 2014 Maserati Quattroporte on a spin along snowy mountain roads to test it for a specific brief: as a limousine for the chauffeured class. It's sporting credentials are impressive: Twin-turbocharged 3.8-liter V8, 532 horsepower, 475 pound-feet of torque in casual circumstances that rises to 532 lb-ft in overboost, a 0-to-60 mile-per-hour sprint of 4.7 seconds and a top speed of 191 mph.
However, citing Maserati's desire to not just increase its sales to 50,000-per-annum by 2015, but to sell many more of its cars in China, Sutcliffe wanted to find out if the livery side of the Quattroporte could match its sport sedan side. So after taking the pilot's seat and trying out the sport settings, Sutcliffe hops in back to test out the CEO's seat.
Then he compares the Quattroporte against the long-wheelbase Jaguar XJ with its supercharged V8, a sedan that's 15,000 pounds less expensive than the Maserati. It doesn't take long for him to find that one of them is a clear winner when it comes to transporting VIPs. To find out which one, enjoy the video below.

2017 Jaguar XE

You've seen this movie before. Topple the BMW 3 Series has gone more rounds than The Fast and The Furious and The Transporter combined. But like any good cinematic retread, this time it's different. For starters, the latest installment is a zombie flick. Born from the ashes of Ford ownership and the failed X-Type, the 2017 Jaguar XE is coming to save us from the somnambulant, undead Bimmer. Think Army of Darkness with luxury sport sedans, and you'll understand what we're going for. Okay, the plot is only based on a true story. The reality in the automotive world isn't as dramatic as most car journalists would like you to believe. But the XE is hugely important for Jaguar's desire to increase global production. You're looking at the future best-selling model. It's built on an all-new body structure that forms the basis for all the brand's upcoming sedans. The smallest, most affordable Jaguar also launches with a new engine family, built in a new factory in England. The XE arrives stateside in early 2016 with two available engines. A 2.0-liter diesel from the new Ingenium lineup is the entry-level model. Above that is the supercharged 3.0-liter V6 familiar to the Jaguar and Land Rover lineup. A turbo 2.0-liter gas engine will come in below the diesel at a later date, with an optional manual transmission. The XE versions on launch will offer rear- or all-wheel-drive. Pricing information is yet to be revealed. Until then, just assume the XE will mimic its competitors for price and content. We spent most of our time driving the 35t with R-Sport trim, but check back for a driving impression of the diesel in a few days. As we reported in our prototype drive of the XE earlier this year, this car has incredible steering feel. It's the supernatural aid in the XE's monomyth if any film buffs are still paying attention. The electrically assisted system ranks in the hall of fame with the rack on the current Porsche 911 Carrera. Lightly weighted, the loads build up in the steering wheel like it's wired to strain gauges on the sidewall of the front tires. It's not just good programming that makes the XE steer so well, although that's a big part. The rest comes from the chassis. Jaguar engineers claim the double wishbone front suspension uses lessons learned from the F-Type. The rear part of the car's quick responses comes from a multi-link setup Jag calls integrated link. A body 20-percent stiffer than the current XF also contributes to sharp reflexes.
