Audi outlasts rivals to win 13th Le Mans title

As is so often the case, the 2014 Le Mans was a war of attrition, and Audi managed to prevail once again after all 24 hours had been recorded in the history books, with its Audi R18 E-Tron Quattro claiming first and second places, followed by Toyota in third. Drivers Marcel Fassler, Andre Lotterer and Benoit Treluyer inherited the lead in their No. 2 Audi after the No. 7 Toyota, driven by pole-sitter Kazuki Nakajima, was forced to retire with electrical problems in the 15th hour.
The No. 2 Audi led the race until it was forced to the pits to replace a turbocharger in the 17th hour, allowing the No. 1 Audi, driven by Lucas di Grassi, Marc Gene (who was a last-minute replacement for Loic Duval, who crashed hard during practice) and defending champion Tom Kristensen, led the race until the 21st hour, when it too had to pit with turbocharger issues. This gave the No. 20 Porsche of Timo Bernhard, Brendon Hartley, and Mark Webber the lead until it was forced off the track with gearbox problems, eventually finishing in 38th position.
In LMP2, the Jota Sport Zytek Z11SN-Nissan driven by Simon Dolan, Harry Tincknell and Oliver Turvey claimed victory, the first five LMP2 finishers all powered by Nissan. Down a level in GTE-Pro, No. 51 AF Corse Ferrari 458 Italia GT2 driven by Gianmaria Bruni, Toni Vilander and Giancarlo Fisichella finished one lap ahead of the leading Corvette Racing C7.R. And finally, the No. 95 Aston Martin Racing Vantage GTE driven by Kristian Poulsen, David HeinemeierHansson and Nicki Thiim won the GTE-Am race two laps ahead of a Proton Porsche 911 GT3 RSR.

2021 Toyota Camry AWD vs. midsize all-wheel-drive sedans | How they compare on paper

Just as crossovers have become the dominant body style in the car market, the all-wheel drive they frequently feature has become more popular. In fact, all-wheel drive is so popular that automakers are increasingly putting it in traditional cars. The latest car to add driven wheels is the 2021 Toyota Camry. It will offer all-wheel drive on most of its trim levels, though only with the four-cylinder engine. It isn't alone in this market, though. So we've compiled the Camry's specifications, along with those of a couple of its competitors for comparison. For the purposes of this analysis, we're sticking with the AWD veteran 2020 Subaru Legacy equipped with a naturally aspirated 2.5-liter engine and the relative newcomer 2020 Nissan Altima. Both are similar in pricing and power to Camry. We've skipped the turbocharged Legacy and the turbocharged Ford Fusion with all-wheel drive as both have higher base prices and significantly more power. We'll take a look at these three sedans engine output, fuel economy, pricing and space. Below is a chart with all the raw numbers, and below that is more in-depth discussion of the cars. Performance and Fuel Economy These sedans are very closely matched, but one area where a clear winner emerges is in output. The Camry has a solid 21 horsepower and roughly 10 pound-feet of torque over the Subaru and Nissan. This, despite all of the engines having the same displacement. That power should make it quicker than the approximately 50-pound-heavier Subaru, though the Nissan Altima may stay with it thanks to its curb weight being about 100 pounds less than the Toyota. Also worth noting is that only the Toyota offers a traditional automatic transmission, whereas the Subaru and Nissan rely on CVTs. Subaru and Nissan have both dramatically improved their CVTs to the point they're quite unobtrusive, but if you strongly prefer the feel of softly shifting gears, the Toyota is your choice. In our experience, all three of these sedans are pleasant to drive with suspension and handling clearly tuned in favor of comfort over quickness. Fuel economy is close to a dead heat. Toyota hasn't announced official fuel economy numbers for the all-wheel-drive model, but we can estimate that, as with most all-wheel-drive variants, mileage will be slightly lower than normal models. We're betting it will only about 1 mpg worse than front-drive variants. That puts it in the same 29 to 30 mpg overall range as the Subaru and Nissan.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.
