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

Audi traffic light recognition could save 240 million gallons of fuel [UPDATE]

Any hypermiler will tell you that the way you drive your car has a huge impact on how much energy it uses. But these greenfoot drivers haven't had a car that's smart enough to tell them about the inner lives of traffic lights. That's what a prototype system in an Audi A6 Saloon that the German automaker recently tested in Las Vegas can do. Since the car can communicate with local traffic signals and is able to predict when lights will change, the car can help reduce CO2 emissions by up to 15 percent. Further, Audi says that the system could save some 238 million gallons of fuel (900 million liters), if deployed across Germany. We can only imagine what hypermilers could do with this. We got to drive the Audi Online traffic light information system prototype in January, but we focused more on how the system worked rather than the green aspect. Now that Audi has had a bit more time to crunch the numbers, it has released fuel economy information for the connected car. The key points for the eco-side of things are that the driver is told in the dashboard how fast/slow to go to hit the next green light. This can help prevent unnecessary speeding and or encourage drivers to go a bit faster in order to hit the green, thus preventing idling and wasted time. The system is too smart to let you idle for long. Except that Audi Online is too smart to let you idle for long. The Audi connect system can calculate how much longer the light will be red and can access the car's start-stop capabilities and will fire up the engine "five seconds before the green phase." That seems like an awful long time in a world where competitors have figured out ways to restart an engine in 0.35 seconds. We've asked Audi for an explanation on why this buffer is so lengthy, and will let you know what the reasoning is when we hear back. Despite the trials in the A6, Audi says the Audi Online traffic system could be integrated into any Audi model, "subject to the necessary government legislation." Aside from the Sin City tests, Audi is running trials of the connected car in Verona, Italy and Berlin, Germany. If you'd like to test it out yourself some day, take heart from this line in the press release, available below: "A market launch is currently the subject of intense analysis in the United States." *UPDATE: Audi's Mark Dahncke told AutoblogGreen that the five second window is meant, "To alert the driver that the light is about to turn green.

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.
