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.

Jaguar Land Rover to cut more U.K. jobs as it moves Discovery output to Slovakia

LONDON — Jaguar Land Rover (JLR) is set to cut more jobs in Britain as it moves all production of its Discovery car to lower-cost Slovakia before building its new Range Rover at an English factory. Britain's biggest automaker, JLR has previously said its next-generation Discovery will be built at its Slovakia plant and on Monday announced there could be some job cuts in Britain as a result. "The potential losses of some agency employed staff in the UK is a tough one but forms part of our long-term manufacturing strategy as we transform our business globally," the company said in a statement. Moving production from Britain will slash several thousands of pounds off the cost per vehicle, the firm's Chief Finance Officer Ken Gregor said last year. The new Range Rover and Range Rover Sport will however be built at the firm's central English Solihull plant on an architecture which is designed to allow for diesel, petrol, electric and hybrid models to be produced. Monday's announcement comes after the firm said this year it will cut 1,000 jobs and reduce production at two of its English factories as demand for diesel cars slumps in the face of higher taxes and a regulatory crackdown. The firm has also blamed Brexit for hitting demand in Europe's second-largest autos market, where demand fell 6 percent last year, a source told Reuters in April. JLR said in January it would decide this year whether to build electric cars in its home market after announcing all of its new cars will be available in an electric or hybrid version from 2020. The company, owned by India's Tata Motors, builds nearly one in three of Britain's 1.7 millions cars but is producing its first electric vehicle, the I-Pace, in Austria. JLR's new factory in the Slovak city of Nitra is due to begin production by the end of the year and will have a capacity of up to 300,000 vehicles. It already employs 1,400 people there as it gears up to open. In Britain, the firm built just over 530,000 vehicles last year at three production facilities and also has a separate engine site and headquarters, employing roughly 40,000 people in total.
