Recharge Wrap-up: Volvo's efficient truck concept, Tesla's updated mobile charger is cheaper

Mercedes-Benz plans to equip its gasoline-powered cars with particulate emissions filters, just like its diesel vehicles. Claiming to be the first automaker to apply the technology to gasoline motors, successful testing in the S500 led to the decision to expand the use of these filters. This announcement coincides with a $3.35 billion investment in clean diesel technology, including a new four-cylinder engine that adheres to strict emissions guidelines. It's not clear when Mercedes will begin including the filters on its gasoline vehicles, or if it intends to use them outside of Europe. Read more at Green Car Reports. Tesla has updated its mobile charger and given it a lower price. The 40-amp "Mobile Connector Bundle" – which used to sell for $650 – is now priced at $550 with two adapters and a storage bag, with an available $520 version offered without the adapters. Tesla's product description reads, "The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets." Read more at Electrek. Volvo has developed a new truck concept that reduces fuel consumption by more than 30 percent. The modified Volvo FH 420 long-haul truck, simply called the Volvo Concept Truck, features 40 percent better aerodynamic efficiency, a weight reduction of about 4,400 pounds, and tires with lower rolling resistance. The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility. While the research vehicle won't reach market as-is, some of its aerodynamic features have already been included in real-world applications, with more to come as Volvo aims to improve the efficiency of its trucks by 50 percent. Read more at Green Car Congress, and in the press release below. Volvo Trucks' new concept truck cuts fuel consumption by more than 30% Almost one-third lower fuel consumption. Volvo Trucks' new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles.

Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

Race recap: 2016 Australian F1 Grand Prix a rowdy start to season

The three brief Formula 1 tests ahead of the current season belied how much had gone on since the last race in November: Infiniti subbed out for Tag Heuer, Renault is back, the all new Haas F1 team, a revamped Manor, three brand new drivers and two returning drivers, a raft of regulation changes among the newly tilled soil. The four engine manufacturers spent a combined 67 tokens among the 138 in the kitty, Renault using just seven of their 32. The only conclusive proof to come from the annual intermission was the otherworldly capability of Mercedes-AMG Petronas. The Silver Arrows didn't even try the super- and ultra-soft tires, focusing on reliability instead of speed. The result? They ran more than 19 race distances, obliterating the lap totals of every other team. There are certainly a few people who enjoyed the complicated new rolling-elimination qualifying format fast-tracked to approval just a few weeks ago. They were wildly outnumbered by those who thought it was awful, including the same team heads who voted for it. We'd probably have to go back to the debacle at the 2005 Indianapolis Grand Prix for an equivalent fiasco when Michelin pulled its teams over safety fears, leaving six cars out of 20 to qualify. In Australia, within 24 hours of the conclusion of qualifying, the new format had itself been eliminated. Nevertheless, qualifying also taught us what didn't happen over the winter: any other team progressing enough to outduel Mercedes. After admitting that he dropped off after winning the championship last year, then getting questioned in the press for some dubious off-season activities, Lewis Hamilton proved he can still turn it on when he wants to. The Brit smoked the Albert Park track in 1:23.837, more than three-tenths of a second ahead of teammate Nico Rosberg in second place. Ferrari did make strides during the off-season, but only enough to keep the same gap it had to Mercedes last year: Sebastian Vettel lined up third, a half-second behind Rosberg, teammate Kimi Raikkonen another four-tenths back in fourth place. Max Verstappen said Toro Rosso is the best of the rest, the Dutchman taking fifth place in front of Felipe Massa for Williams in sixth and Toro Rosso teammate Carlos Sainz in sixth. Daniel Ricciardo – who wasn't smiling after qualifying – kept Red Bull and its new "Tag Heuer" engines in the conversation with eighth on the grid.
