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 20d Quick Spin

Base models rarely get their due in the press. Big-engine, high-horsepower variants get all the headlines, but the junior version is what sells in volume. We're just as guilty here at Autoblog, with both a first and second drive of the Jaguar XE in supercharged V6 guise, and barely a mention of the entry-level, 2.0-liter diesel. So, in Perd Hapley style, the Jaguar XE diesel is the model of the Jaguar XE we're going to discuss. Yes, the volume model of the Jaguar XE is a diesel, at least for now. A turbocharged 2.0-liter gas engine, wearing the 25t badge, will arrive after the XE's early 2016 on-sale date. Oil-burners and volume are not a thing in the United States, except for heavy-duty pickup trucks. Despite that apparent contradiction, the XE 20d could find some converts. Driving Notes The biggest clue to the engine's fuel source is the tachometer, which only counts to 6,000. But you wouldn't know from the fast throttle response or the way revs climb when you mash the accelerator. All 180 peak horsepower come at 4,000 rpm, and the 317 pound-feet of torque are available from 1750 to 2500 rpm. Really, this engine is smooth. Credit the low 15.1:1 compression ratio, which also helps make the engine's aluminum construction possible. The surge of power from the turbo builds steadily instead of kicking in all at once. Jaguar's engineers focused on friction reduction with a fanatical devotion, all in the name of efficiency. One key feature is the offset crankshaft. That is, the crankshaft is located to the side of the cylinder centerline. This reduces the side load forces during the firing cycle. In the manual transmission the gears are cupped to reduce mass. A pump sprays oil directly on the cogs, which cuts back on the total amount of fluid and cuts back on friction loss due to windage. No, the manual transmission isn't coming to the US. And yes, it's really good. Not just in the cliche journalist love for the diesel-manual combo, but objectively good. That smooth responsive nature of the engine is amplified when you get to choose your own gears. So we make due with the eight-speed automatic, the 8HP45 version of the ubiquious ZF box. The coolest trick here is a pendulum-style damper in the torque converter instead of a typical spring damper. When the torque converter is locked up this cuts down on torsional vibration between the engine and transmission. And that enables low-rpm cruising and higher mpg.

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.
