Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.

Rivian R1T, Mini Cooper Electric owners happiest with their EVs

The J.D. Power 2023 U.S. Electric Vehicle Experience (EVX) Ownership Study is out, and there's change at the top. With the swelling adoption of electric vehicles in the U.S. over in the past two years especially, the third year of the EVX study changes focus to first-time EV buyers. Those two factors encouraged change at the top of both premium and mass-market segments. Among premium EVs, the Rivian R1T pickup scored overall victory in its first year of eligibility with a satisfaction score of 794 out of 1,000. The Tesla Model 3 takes second place with 759 points. Tesla had won the top two premium spots in the study in 2021 and in 2022. The average score in the premium segment was 756. The Tesla Model Y (754), Audi E-Tron (735), and Polestar 2 (724) filled out the list of the five eligible models this year. Among the ten eligible mass-market vehicles, the Mini Cooper Electric nabbed the overall win by scoring 782. The Kia EV6 came second with 762 points, keeping Kia in the top two; the Kia Niro EV won the mass-market segment the previous two years. The Ford Mustang Mach-E (742), Hyundai Ioniq 5 (738), and Volkswagen ID.4 (735) completed the top five, the Niro EV (733) in sixth. All were above the segment average of 730. The four models fell below the segment average were the Ford F-150 Lightning (723), Chevrolet Bolt EUV (716), Chevrolet Bolt (711), and Nissan Leaf (698). How are the scores derived? J.D. Power worked with EV app maker and research firm PlugShare to get owner responses in ten areas: accuracy of stated battery range; availability of public charging stations; battery range; cost of ownership; driving enjoyment; ease of charging at home; interior and exterior styling; safety and technology features; service experience; and vehicle quality and reliability. Brent Gruber, executive director of the EV practice at J.D. Power, said, "Recent vehicle launches from both new brands and traditional automakers have had a profound effect on what factors are most important in the ownership experience. Today’s EV owners are looking for quality, reliability, driving enjoyment, safety and technology features." The Mini, in fact, scored highest of any premium and mass-market EV in the studyÂ’s highest-weighted index factor, quality and reliability.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.
