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

Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.

VW won't let emissions scandal keep it from racing

The Volkswagen Group may have its hands full dealing with the diesel emissions scandal. But that doesn't mean it will be curbing its considerable racing programs. At least not in any significant way. This according to Matthias Muller, who recently moved up from his previous position as Porsche CEO to preside over the entire group. Speaking with Autosport at the World Endurance Championship finale in Bahrain this past weekend, Muller emphasized the importance of racing to the company. "The motorsports programs are not in danger of being dropped or significantly reduced because motorsports is very important for the group and the brands," said Muller. "Basically we do not question our motorsport efforts." Of all the brands under the group's umbrella, several have prominent, top-level factory works racing programs, and others support customer racing teams. The Volkswagen brand has emerged as the dominant force in the World Rally Championship, securing both titles over the past three years. Both Porsche and Audi compete in the top tier at Le Mans and in the World Endurance Championship, trading places in the winner's circle. Audi also competes in DTM, and alongside Lamborghini, Bentley, and Porsche, and also offers GT3 and GTE racing cars to private customers. Lamborghini, Porsche, Audi, and Seat (once the leader in touring cars) all run their own spec racing series as well. Skoda continues to compete in lower-level rallying, leaving only Bugatti to draw on its prominent pre-war grand prix racing history. To hear Muller tell it, those racing programs – or at least the top-levels ones among them – aren't going away anytime soon. But there may still be some tweaks here and there, and we shouldn't expect any new programs to be launched in the near future. Porsche, for example, is anticipated to wind down its factory involvement in GT racing, after winning both the drivers' and manufacturers' titles in the WEC GTE Pro class this year in addition to its LMP1 victories. Instead it will focus on preparing new racing versions of the 911 for client racing teams. The auto giant was also reportedly close to branching out into Formula One in partnership with Red Bull. But after negotiations were interrupted by emergence of the diesel emissions scandal, that deal fell apart. It remains unknown which brand might have been represented in the F1 engine-supply program.
