Mercedes FWD platform to last until 2018, convertible and two-seater future uncertain

Mercedes-Benz seems to be expecting a lot of success from its front-wheel-drive CLA-Class. Automotive News is reporting that the sub-C-Class sedan could grow when its second generation arrives in 2018.
The current FWD platform for MB underpins the CLA, the B-Class, the GLA-Class, and the A-Class. The B-Class will arrive in North America as an EV for spring of 2014, while the production GLA crossover will arrive three to four months after that. The five-door A-Class won't be crossing The Pond. Sad faces all around.
According to AN, another model will be based on the front-drive architecture, but it won't be coming to the US market. Set to arrive next year, rumors are that it'll be a wagon version of the CLA, sort of like the ill-named five-door CLS Shooting Brake that is also a Europe-only item.

2015 Australian Grand Prix all about grooves and trenches [spoilers]

We can't remember the last time 90 percent of the action in Formula One had nothing to do with cars setting timed laps. Yet that's was the situation at the Australian Grand Prix, continuing the antics from a scarcely believable off-season with blow-ups, driver and team absences, a lawsuit, and a clear need for some teams to get down and give us 50 pit stops. Nothing much has changed from a regulation standpoint, and at the front of the field nothing has changed at all. Lewis Hamilton in the Mercedes-AMG Petronas claimed the first position on the grid like someone put a sign on it that read, "Reserved for Mr. Hamilton;" teammate Nico Rosberg was 0.6 behind in second, Felipe Massa in the Williams was 1.4 seconds back in third. Sebastian Vettel proved that Ferrari didn't do another Groundhog Day routine this off-season, slotting into fourth. His teammate Kimi Raikkonen was not even four-hundredths of a second behind, ahead of Valtteri Bottas in the second Williams, Daniel Ricciardo in the first Infiniti Red Bull Racing, and rookie Carlos Sainz, Jr. in the first Toro Rosso. Lotus, now powered by Mercedes, got both cars into the top ten with Romain Grosjean in ninth, Pastor Maldonado in the final spot. However, even though the regulations are almost all carryover, in actual fact, everything has changed this year. Mercedes is even faster. Renault is even worse. Ferrari and Lotus are a lot better. Toro Rosso is looking like anything but a junior team. And McLaren is – well, let's not even get into that yet. Furthermore, this weekend was shambles: 15 cars started the race, the smallest naturally-occurring grid since 1963. Manor couldn't get its cars ready before qualifying. Bottas had to pull out after qualifying when he tore a disc in his back and couldn't pass the medical clearance tests. The gearbox in Daniil Kvyat's Red Bull gave out on the lap from the pit to the grid, and to give misery some company, the Honda in Kevin Magnussen's McLaren blew up on the same lap. When the lights went out, Hamilton ran away and was more than a second ahead of his teammate at the end of Lap 1. The advantage disappeared, though, because behind him, at the first corner, we got our first pile-up. As Raikkonen drove around the outside of Vettel at the right-hand Turn 1 it looked like Vettel, going over the kerbing, hopped to his left and bounced into Raikkonen.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
