2014 BMW 4 Series drops its top, priced from $48,750*

BMW will debut its new 2014 4 Series Convertible at the Los Angeles Auto Show in November, and after seeing plenty of spy shots and, most recently, some leaked images, we now have all the official details. To no one's surprise, the 4 Series convertible is, essentially, a topless version of BMW's new-for-2014 4 Series coupe, and will be offered in the United States in the same 428i and 435i guises.
On the base end, that means the 428i Convertible arrives with the company's 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and available with either rear- or all-wheel drive. BMW says the 428i will sprint to 60 miles per hour in a respectable 6.2 seconds. For folks in need of more thrust, BMW will happily sell you a 435i Convertible, available only with rear-wheel drive, powered by a 3.0-liter, twin-turbocharged inline-six that produces 300 hp and 300 lb-ft of twist. Hitting 60 mph in the 435i will take roughly five and a half seconds with the standard eight-speed auto. Curiously, BMW did not mention anything about a six-speed manual transmission for either model, so looks like this droptop might be an auto-only affair. We've contacted BMW for confirmation, so we'll keep you posted.
Like the 3 Series Convertible it replaces, the 4 Series uses a three-piece folding hardtop configuration, and BMW says that added sound deadening reduces audible wind noise by about two decibels. Folding the automatic roof takes just 20 seconds, and can be done at speeds up to roughly 11 mph. For chilly, top-down driving (something we're big fans of), there are now three-temperature neck warmers for the front seats - just like what Mercedes-Benz offers with its AirScarf system.

Recharge Wrap-up: Tesla opens 50th European Supercharger, BMW smart charging in Singapore

Southeastern Illinois College wants to create a biofuel processing certification program. The school is waiting to hear about receiving $750,000 from a US Department of Labor grant that would allow it to expand its Biofuels Education curriculum to include certification for manufacturing biodiesel and ethanol. There are currently no such programs in existence, and its development would require Labor Department approval as well as input from biofuel companies. Southeastern Illinois College believes that biofuel processing certification would be a large draw for potential students. Read more at The Southern Illinoisan. Tesla has opened the 50th Supercharger in Europe. In the year since the first on was installed in Norway in August 2013, Tesla has been building the network that, like it does in the US, will allow Model S drivers to go long distances for free. There are now 168 Superchargers open throughout the world. Find more in the press release below. BMW is partnering with Greenlots to bring an open standards EV charging network to Singapore. As part of BMW's 360 Electric program, Greenlots will install public chargers and manage the network that allows BMW i owners to find and use the chargers with BMW's navigation system and ChargeNow card. The 30 possible public chargers Greenlots plans to install will use the company's SKY Smart Charging platform. Greenlots will also install the BMW i Wallbox Pure charger at customer's homes and offices. Read more in the press release below. Plug-in electric vehicle (PEV) sales are forecast to reach 1.8 million a year by 2023, according to a report by Navigant Research. Right now, North America is the biggest buyer of battery-electric and plug-in hybrid vehicles, but that should change as the Asia Pacific market is expected to outgrow it; still, the US alone is expected to have more than 2.7 million PEVs on the road in 2023. Urban areas are where we'll see the largest concentration, naturally, with Tokyo, Los Angeles and Paris having the most sales in 2023, respectively. With the increase in PEVs comes an increase in residential load on the electric grid, which is expected to rise by 33 to 37 percent.

The small, two-seat urban EV has a limited speed of 50 miles per hour, but has a range of up to 100 miles.

BMW i3 qualifies for both green and white HOV stickers in California

BMW buyers tend to have enough cash on hand to be buffered from the concept of "sticker shock," but the term may take on a different meaning when it comes to the German automaker's i3 plug-in vehicle and its classification by California clean-air regulators. The first i3 EVs are set to be sold in May, and some are questioning if the new car will be eligible for the state's white stickers or green High-Occupancy Vehicle lane stickers, both of which allow for solo-occupancy in HOV lanes. California gives out white stickers to some types of battery-electric vehicles, compressed natural gas (CNG) vehicles and hydrogen fuel-cell vehicles, and there's currently no limit on the number that can be given out. The green stickers, which are applied to other battery electrics as well as some plug-in hybrids, are limited (there are currently about 15,000 left) and will likely run out within the next year or two. The i3's status is uncertain because of it has an optional gas-powered range-extender. Jacob Harb, head of electric vehicle operations and strategy for BMW, told AutoblogGreen that it's not all that complicated. The pure electric version of the i3 will get the white sticker, the REx version will get the green sticker. He also said that both will qualify for the $2,500 state incentive in California and the $7,500 federal tax credit available in all 50 states (For what it's worth, Green Car Reports says the REx version will only get $1,500 from California).
