2016 Jaguar XF to hit 60 mph in 5 seconds, lead with cutting-edge infotainment

Since the second-gen XF's unveiling last week in an epic publicity stunt over London's Canary Wharf, the details on the new four-door have been rather scarce. That changes now, with the Jaguar revealing just about everything we could hope to know... aside from the price and fuel economy. As we covered in our original post, Jaguar has trimmed the weight for both rear- and all-wheel-drive variants by 132 pounds and 265 lbs, respectively. That means that, regardless of engine output, the two-wheel-drive model tips the scales at just 3,770 lbs, while the AWD XF slips in at 3,880. This was mainly done by way of aluminum construction – the 13th element constitutes 75 percent of the XF's structure – although ultra-high-strength steel also plays a role. Jag claims these elements not only reduce weight – which is almost perfectly distributed, with a "near" fifty-fifty ratio – but increases torsional rigidity by 28 percent. The new XF should be just as agile as the brand's namesake, thanks not only to the reduced weight and stiffer structure, but also to a new chain-driven all-wheel-drive system that's both lighter and more efficient than a traditional version. Impressive though that may be, the brand's Intelligent Driveline Dynamics system is the standout here. IDD manages the torque split, diverting power to the rear axle until it predicts, through factors like yaw rate, steering angle and lateral acceleration, when torque should be shifted to the front wheels. Moreover, the AWD system features Adaptive Surface Response, which takes the place of the old XF's winter driving mode. It monitors road conditions, modifying the behavior of the sedan's systems as needed. The second-gen sedan comes to the US in 340-horsepower and 380-hp variants – torque remains fixed at 332 pound-feet – courtesy of Jaguar Land Rover's familiar 3.0-liter, supercharged V6. The new XF's straight-line performance should be just as entertaining as it sounds, too. The rear-drive, 340-hp XF will hit 60 in 5.2 seconds, while the rest of the range can get there in 5.0. That marks a significant reduction compared to the first-gen V6 models, which used their 340 hp to sprint to 60 in a more leisurely 5.7 to 6.1 seconds. Regardless of output, the rear-drive XF will outrun both the BMW 535i and Mercedes-Benz E350 (we're still waiting on performance figures for the 329-hp E400, so Jag's RWD dominance may not last), which take 5.5 seconds and 6.5 seconds, respectively.

Jaguar releases C-X75 concept build story

If you want to know what was going through the minds of decisionmakers at Jaguar when the company decided to build the batty C-X75 Concept, look no further than the quick video after the jump. Jaguar set about building a car with the performance of a Bugatti Veyron, the electric range of a Chevrolet Volt and the emissions of a Toyota Prius, and they turned to a legendary engineering firm to help make it happen. Williams, the same crew behind Williams F1, helped Jaguar stitch the concept car together, and the result is unlike anything we've seen before.
The twin-charged 1.6-liter four-cylinder mounted amidship is paired with an electric motor at each wheel for a combined output of over 850 horsepower. And, since the whole chassis is hewn from carbon fiber, a production version would've been light enough to give machines like the McLaren P1 and Ferrari LaFerrari a run for their money. Shame they apparently couldn't make the business case work. Watch the concept build story in the video below for yourself.

2017 Jaguar XE: We'll miss our long-termer, but not its diesel engine

This may be automotive journalist blasphemy, but diesels aren't always a good thing. And I don't mean that from an emissions standpoint. Sometimes the diesel in question isn't a good engine, and/or is a bad fit for the cars to which they're fitted. Our long-term Jaguar XE diesel is a textbook case of both issues. The first issue becomes apparent from the moment the 2.0-liter turbodiesel four-cylinder fires up with all the clattering, tapping and ticking that can only come from a compression-ignition engine. It's far from the shaking and knocking of full-size diesel trucks of a few decades ago, but it definitely feels a generation or two behind other diesel cars. For instance, we had a diesel Chevy Cruze in the office, which was quieter and smoother than the Jaguar despite a base price roughly $10,000 less. It becomes a bit smoother and less raucous as revs increase, but the volume remains rather high, making it sound as though the engine is struggling more than it is. Though, to Jaguar's credit, the company has managed to keep virtually all engine vibrations from entering the cabin. Now, the diesel engine's voice would be less problematic if it provided some engaging performance, but, outside of the high fuel-economy numbers, there's hardly any to be found. This may seem surprising considering the Jaguar's 318 pound-feet of torque, but that torque figure lasts only briefly from 1,750 rpm to 2,500 rpm. After that, the torque rapidly falls off, and you don't see the Jag's meager 180 horsepower peak until 4,000 rpm -- not far off of the engine's roughly 5,000-rpm redline. As a result, the XE has adequate passing power and around-town shunt, but anytime you want to play with more revs, it faceplants. But at least it does nail, and even exceed, its 40-mpg highway fuel economy rating without trying. The faults of this diesel engine are then exacerbated by the fact that it's in such a smooth and fun car as the XE. It positively glides across rough city streets and highways, keeping the chassis steady and its passengers soothed. Coupled with a quiet cabin, the XE is a peaceful place to be. At least it would be if the diesel didn't rudely interrupt every time the throttle pedal is pressed. Through some sort of black magic, the XE handles about as well as it rides. The incredibly sensitive and accurate steering is superb. It feels like adjustment knobs on a high-end stereo -- weighted perfectly and fine enough to get it right where you want it.
