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.

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.

Audi and Jaguar Land Rover recalls address seatbelt issues

Audi and Jaguar Land Rover are each recalling several thousand vehicles for separate potential seatbelt issues. The recalls cover the 2022 Audi A3 and S3; 2022 Jaguar F-Type, F-Pace and XF; and the 2022-23 Land Rover Defender, Discovery, Discovery Sport, Range Rover Sport and Range Rover Velar. Examples of these vehicles may have shipped with seatbelt pretensioners that will not function properly in the event of an accident.  Audi is recalling its sedans for tensioner devices that may not adequately restrain drivers or passengers during a crash. The issue was discovered during Korean market crash testing of the high-performance RS 3.  "The seat belt tensioner in the affected vehicles serve the purpose of holding the passenger in his position in the seat," Audi said in its defect report to NHTSA. "In the event of a crash, the retention force of the seat belt may not reach the intended level. As a result, the position of the body can be further to the front of the seat, which leads to a negative influence on the whole restraint system, increasing the risk of injury." A different company, Jaguar Land Rover (JLR), meanwhile, also has an issue with a batch of pretensioners installed in its cars and SUVs. Pretensioners are the devices that fire off to rapidly retract the seatbelt when a crash is detected. Most utilize an explosive charge and pressure tube JLR says that some pretensioner devices provided by one of its suppliers may not have properly-specified pressure tubes that may not channel the gasses to the retraction mechanism correctly.  "A damaged front seat belt pretensioner tube may have been installed on the seat belt retractor," JLR's report said. "This may result in a reduced level or complete loss of pre-tensioning in the event of a crash and increased occupant injury." Owners of the models included in both recall campaigns should receive notices from the manufacturers in the coming months.  Related video: Recalls Audi Jaguar Land Rover Ownership Safety SUV Sedan
