Recharge Wrap-up: BMW's electric truck, London's electric double-decker bus

BMW and transport and logistics company Scherm Group have put an electric transport truck into service in Munich, Germany. The 40-ton truck, made by Dutch manufacturer Terberg, will be used to move vehicle components between BMW's Munich plant and Scherm's logistics center cleanly and quietly on public roads. Using the electric vehicle saves 11.8 tons of CO2 per year. It charges in about four hours, and has a range of about 62 miles — enough to make the trip between the two facilities eight times a day. The truck will be powered completely by electricity from renewable sources. With this project, BMW "is showing that you can succeed on the global market with sustainable products made by innovative companies," says Bavaria's Minister for Economic Affairs, Ilse Aigner.

The company has installed fast-charging stations at 50 locations for customers to use while they shop. IKEA also has plans to install free charging at its stores in Germany, and other retailers will likely do the same. While offering free e-juice helps businesses garner the attention of its EV-driving customers, it could also help encourage people to buy electric vehicles. Many are disappointed by Germany's lack of EV incentives, despite the country's goal of having 1 million EVs in operation by 2020. Read more at Automotive News Europe. London will put an all-electric double-decker bus into service this year. London Mayor Boris Johnson announced the electric bus trial at the first ever Clean Bus Summit. The bus, made by BYD, will begin service in October. London has already deployed over 1,300 hybrid buses and retrofitted over 1,400 buses to reduce emissions since 2008. Mayor Johnson's goal is to cut buses' NOx emissions in half by the end of his term in 2016 compared to 2008 levels. Also at the Clean Bus Summit, a number of bus makers and banks committed to helping cities roll out fleets of ultra-low emission buses. Read more in the press release from London, and from BYD. The US Department of Energy (DOE) is funding biofuel projects to the tune of $18 million. The DOE will award the funds to six projects in an effort to reduce the price of algae-based biofuels to less than $5 per gasoline gallon equivalent (gge). The DOE has a goal to get the price of algal biofuels to less than $3 per gge by 2030.

The best cars we drove this year

Six hundred and fifty. That's roughly how many cars pass through the hands of Autoblog editors every year, from the vehicles we test here at home, to the cars we drive on new product launches, testing roundups, long-term cars, and so on. Of course, our individual numbers vary due to several reasons, but at the end of the day, our team's repertoire of automotive experience is indeed vast. But let's be honest, some cars certainly stand out more than others. So as the year's about to turn, and as we're readying brand-new daily cat calendars for our cubicles, our editors are all taking time to reflect on the machinery that made this year so special, with one simple, open-ended question as the guide – a question that we're asked quite frequently, from friends, family, colleagues, and more. "What's the best car you drove this year?" Lamborghini Huracan When I review the list of everything I drove in 2014, picking an absolute favorite becomes almost impossible. I mean, how does one delineate between the joy offered by cars as different as the Alfa Romeo 4C, Volkswagen Golf R, Mercedes-AMG GT S and even the humble-yet-wonderful Chevy Colorado? Okay fine, I'll just pick the Lamborghini. I drove the Lamborghini Huracan LP 610-4 on a racetrack, in the mountains, and along southern coast of Spain. It felt like the king of the car jungle in all of those places, sucking the eyeballs of observers nearly out of their heads as it drove by, and almost melting my brain with its cocktail of speed and grip and intense communication. It feels a little easy to say that the one new supercar I drove this year was also my favorite, but the fact is that the Huracan is one of the finest cars I've driven during my career, let alone 2014. Judge me if you must. – Seyth Miersma Senior Editor Rolls-Royce Wraith There are a couple of ways to look at the question, "What's the best car you drove this year?" In terms of what was so good I'd go out and buy one tomorrow, that'd be my all-time sweetheart, the Volkswagen GTI. Or if I'm just talking about sheer cool-factor, maybe something like the Galpin GTR1, BMW i8, or Mercedes-Benz G63 AMG. But instead, I'm going to write about the sheer opulence of being the best of the best. The hand-crafted, holier-than-thou, shut-your-mouth-when-I'm-talking-to-you supremacy. I'm picking the Rolls-Royce Wraith. I drove the Wraith for a week in April, and was really, really impressed. This car does everything, perfectly.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
