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

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

An amazing Group B rally car collection heads to auction

Kicking off in 1982, the Group B era spawned some of the most fearsome rally cars of all time. The technologically advanced pioneers of all-wheel drive and turbocharging defined a time when automakers had carte blanche to build machines with unrestricted power, without the burden of homologating a large number of road cars to qualify. The results were sometimes deadly, leading the FIA to ban the class after 1986. Now, a collection of seven Group B monsters is headed across the block in Paris as part of the Artcurial auction, held in partnership with France's famed Retromobile show. The show has been delayed to June, however. There's a 1985 Peugeot 205 Turbo 16, one of 20 Evo II models that helped the company achieve two championships in Group B's short run. This particular example was driven by world champion Timo Salonen at the 1986 Swedish Rally, where it finished seventh due to an oil filter seal failure. Bruno Saby subsequently drove it at the 1986 Tour de Corse and Peugeot entered it at the 1986 Acropolis Rally as well. It's still registered to Peugeot Talbot Sport and represents a French technological achievement, according to Artcurial, comparable to the Concorde or TGV train. Representing Italy are a pair of Lancias in the iconic Martini livery. The Lancia 037 helped Bel Paese clinch its only Group B victory in 1983, after a hard-fought rivalry with Audi. It's one of the few Group B cars that weren't AWD, achieving its success the old-fashioned way, through lightness and superb handling. A second Lancia, a 1986 Delta S4, was the culmination of the Italian firm's later Group B efforts and one of Saby's favorites. While Group B was no more in 1987, the S4 was the predecessor to the Delta Integrale that would dominate WRC from 1987 through 1992. While the collection also includes greats like a Ford RS200, Renault 5 Maxi Turbo, and MG Metro 6R4, the centerpiece is the Audi Quattro Sport S1. The ultimate Group B machine, it introduced all-wheel-drive and turbocharging to the sport. It also employed the wildest use of wings and air dams to generate downforce. Tunable up to 590 horsepower, it could rocket to 60 mph in about three seconds. The car offered for sale came straight from Ingolstadt, a 1988 model built for the Race of Champions of ex-Group B cars. The collection was amassed in the late 80s and early 90s, not long after Group B's dissolution.
