Mercedes chief invites Audi, BMW to compete in F1

Mercedes-Benz didn't just win the Formula One World Championship in 2014 – it positively dominated it. The team won all but three of the grands prix this season, scoring a one-two finish at more than half of them and landing at least one car on the podium at every race without exception. It goes without saying, then, that the German automaker thrives on competition, but now it's welcoming even more. Speaking with Germany's Sport Bild at its homecoming celebration in Stuttgart, Daimler chief Dieter Zetsche welcomed Mercedes' biggest rivals Audi and BMW to join it on the F1 grid. Noting that the three German brands share some 80 percent of the market for luxury automobiles, Zetsche said that F1 would make a natural arena of competition for Mercedes, Audi and BMW to fight for top bragging rights. The three currently compete against each other in front of home audiences in the DTM touring car series – effectively Germany's equivalent to NASCAR – but of the ten races held this year, the majority were in Germany itself, and all of them took place in Europe. BMW last competed in F1 when it bought the Sauber team in 2006, but withdrew from the series in 2009. Despite its progenitor Auto Union having fielded the famous Silver Arrows in pre-war grand prix racing, Audi has never been a player in modern F1 racing, though recent rumors have linked it to a potential foray – spurred by the arrival of sister-company Porsche on its home turf at Le Mans, the departure of several of its key endurance drivers and the hiring of former Scuderia Ferrari chief Stefano Domenicali. Porsche had similarly considered an F1 program before getting the go-ahead to compete with Audi at Le Mans. As for the prospect of Mercedes competing in other international racing series, Zetsche added that year-long preparations for 24 hours of racing at Le Mans didn't present a good cost-benefit ratio in his estimation, but that Formula E (where Audi currently supports a quasi-works entry) would be worth a closer look.

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.

Mercedes-Benz GLE gets official before NY Show

Hot off the debut of the GLE-Class Coupe just a few months ago at the Detroit Auto Show, Mercedes-Benz is now all set to unveil that SUV's more utilitarian sibling. The new GLE-Class will offers buyers a model that's a little more traditional looking, while still bringing heaps of available power and luxury to the table. The new GLE-Class replaces the ML-Class in Mercedes' newly renamed lineup. At the front, there's a new nose with a clear family resemblance to the Coupe. It sports big openings all over, and standard models wear an attractive two-bar grille or a just a single crosspiece for AMG trims. Once your eye moves past the A-pillar, the design becomes more of an evolution of the current ML. The prominent C-pillar and wraparound rear glass are still present, while the creases running down the profile appear a little sharper and more pronounced. As you might expect, the interior for the GLE-Class is practically identical to its Coupe counterpart. That means drivers get a thick, multi-function steering wheel to hang on to, and there's a large infotainment display poking up above the dashboard in the center. A center-console-mounted dial controller is found below. When it comes time for buyers to pick their GLE-Class, they're going to have a long list of powertrains to choose from. Lowest in terms of horsepower is the GLE300d 4MATIC with a 2.1-liter, four-cylinder diesel making 201 hp and 369 pound-feet of torque. Next, there is the gasoline-fueled GLE350 with a 3.5-liter V6 making 302 hp and 273 lb-ft, and it's also available with 4Matic. The GLE400 4Matic uses a twin-turbo 3.0-liter V6 to make 329 hp and 354 lb-ft of twist, and the GLE550e 4Matic adds a plug-in hybrid to that mill to bring total output to 436 hp and 479 lb-ft. Finally, for those that really want some power underfoot, the Mercedes-AMG GLE63 and GLE63 S boast twin-turbo 5.5-liter V8s putting down 550 hp and 577 hp, respectively. The standard models all use versions of the 7G-tronic gearbox, and AMG models get the Speedshift MCT seven-speed. We look forward to getting a good look at the GLE-Class at its grand unveiling at the New York Auto Show on April 1. The posh SUVs start arriving at dealers a few months later in August. Buyers wanting the GLE550e 4Matic have to wait just a little longer until it comes along in mid-September.
