2015 Mexican Grand Prix is a lot like old times

The last time Formula One visited Mexico, in 1992, 26 cars powered by eight engine manufacturers (counting Honda and Mugen-Honda separately) lined up on the grid; it would have been nine engine makers but the Brabham-Judd cars failed to qualify. In 1992 Lewis Hamilton was seven years old, Sebastian Vettel was five, Max Verstappen was still five years away from being born. Two of the current Sky Sports F1 commentary team, Martin Brundle and Johnny Herbert, were drivers. The starting three were Nigel Mansell on pole – 39 years old, this the year he'd win his only World Championship – and Riccardo Patrese both driving Williams-Renault cars, followed by Michael Schumacher in a Benetton-Ford. Only 13 of the 26 starters would finish. The circuit is has been reworked to today's safer standards, the track surface is brand new and slippery, but the atmosphere and packed grandstands haven't changed. Nico Rosberg was another point of consistency, scoring pole position for the fourth race in a row to beat his now-World-Champion teammate Hamilton by almost two-tenths of a second. The last time Rosberg turned pole position into a victory? The Spanish Grand Prix back in May. Vettel locked up third for Ferrari, followed by the Infiniti Red Bull Racing duo of Daniil Kvyat and Daniel Ricciardo. Williams went two-up as well, Valtteri Bottas in sixth ahead of Felipe Massa in seventh. Max Verstappen turned in a great late lap to reserve eighth place, Sergio Perez did all he could in front of his home crowd to get ninth, teammate Nico Hulkenberg the caboose in the top ten. In that 1992 race the first three on the grid finished the race in the same order after Mansell dominated, and it was almost the same in 2015. If Rosberg had driven the whole season like he drove today the Driver's World Championship would still be up for grabs. He got a great start and held his line through the first corner, coming out ahead of Hamilton through the initial kinks, pulling away as soon as he got to the straight. Hamilton was never more than a few seconds behind, but every time the Brit inched closer the German found a few more tenths to keep his distance. The field got bunched up when the Safety Car came out on Lap 53 after Vettel spun and got stuck in the barriers, but Rosberg handled the restart perfectly. Both drivers made small mistakes in the last few laps while driving on the edge, but Rosberg earned a strong victory, crossing the line two seconds ahead of his teammate.

2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

Chris Harris falls in love with Mercedes-AMG GT at Laguna Seca

It's not every day that an automaker goes down a market segment and still comes off as even more ambitious, but that's exactly what Mercedes has done with the new AMG GT. While the SLS was bigger and more expensive, with the new GT, Mercedes has set its sights on one of the most iconic sports cars of all time. That, of course, would be the Porsche 911, and the big question is whether Benz has achieved its target. For the answer, we turn to none other than the Monkey himself – the inimitable Chris Harris, who recently went solo with his own YouTube channel. And for his latest segment, he took the latest German sports car around no less suitable a track than Mazda Raceway Laguna Seca.
