Worldwide debut of the all-new BMW i3.

The new all-electric BMW i3 is a landmark in BMW's mission to provide a completely sustainable, electric vehicle that still stays true to the Ultimate Driving Machine moniker. The BMW i3 is the first product of the new BMW i sub-brand, and is a truly purpose built electric car. It's a new era for electro mobility at BMW.

The vehicle concept behind the BMW i3 was designed from the outset to incorporate an all-electric drive system. This has numerous advantages over "conversion" vehicles, in which the original combustion engine is swapped for an electric motor. The engineers can design whatever works best, in terms of construction, dimensions and configuration of the electric drive system's components. The car's development is dictated by the characteristics designed into the car by the development team and not by the constraints imposed by a pre-existing vehicle design. For example, the space in a conversion vehicle set aside for the fuel tank or exhaust system cannot be used. In the BMW i3 there is no need for this kind of compromise.

This leads to the LifeDrive architecture concept, which was purpose-built specifically for the BMW i3. It is comprised of two modules; the Life Module, and the Drive Module. Think of the Life Module as the passenger cabin, or greenhouse. It is the first-ever mass produced Carbon Fiber Reinforced Plastic (CFRP) passenger cell in the automotive business, and is a big factor in the cars efficiency. Carbon Fiber Reinforced Plastic is equally as strong as steel, while being 50% lighter, and 30% lighter than aluminum. The result is an electric car that weighs about 2,700 lbs (preliminary US figures).

Due to the lightweight, high tensile strength of CFRP, the passenger cell has added protection, and the battery has less work to do, which allows for the use of a smaller, lighter battery that saves even more weight, reduces charging time and increases range. The light weight design of the Life Module also lowers the BMW i3's center of gravity, making it a more engaging and dynamic car to drive.

The Drive Module, which is constructed out of 100% aluminum, consists of the 22-kWh, 450 lb. lithium-ion battery, electric drive train, MacPherson strut and 5-link rear suspension system and structural and crash components. The battery mounted in the rear, close to the drive wheels, gives impressive performance characteristics while also providing better traction.

Another benefit of the LifeDrive architecture concept is that there is no space-consuming transmission tunnel running through the center of the car, like in most internal combustion powered cars, because of the separate Drive Module. This gives the BMW i3 the interior space of the BMW 3 Series, while only having the footprint of the much smaller BMW 1 Series.

Even the vehicle's key is sustainably manufactured. The source material of the new bio-polymer key is based on castor oil pressed from castor seeds. The owner's manual is also made from renewable resources.

The interior is made using high quality renewable sources and recycled materials. The BMW i3 has the Next Premium interior, which blends sustainable resources with a premium feel for the same interior quality as the BMW 5 Series Sedan. 25% of the plastics in the interior and 25% of the thermoplastic parts on the exterior are made from either recycled materials or renewable sources.

According to studies carried out as part of BMW's Project i, involving more than 1,000 participants and conducted over some 12.5 million miles, it was revealed that the average daily distance covered was around 30 miles. The BMW i3 will be able to travel 80 to 100 miles on a single charge. This can be increased by up to approximately 12% in ECO PRO mode and by the same amount again in ECO PRO+ mode. It is able to recharge in only 3 hours with the use of a 220V Level 2, 32-amp J1772 charger. The SAE DC Combo Fast Charging, which charges the BMW i3 up to 80% in 20 minutes, and 100% in 30, can be had as an option.

In order to reduce range anxiety, a rear-mounted 650cc, 34 hp, two-cylinder, gasoline-powered Range Extender generator is available, which roughly doubles the vehicle's range. When the battery gets to a certain level, the Range Extender starts and maintains the battery's current state of charge. The Range Extender never directly drives the vehicle's wheels. The Range Extender adds roughly 330 lbs. to the vehicle curb weight and has a fuel capacity of 2.4 gallons.

Since 1999 according to the DOE, average gasoline prices in America have increased from approximately $1.136 to $3.618, or about a 218%. In the same time, the pricing of electricity has increased from 6.6 cents to 9.9 cents, a change of only 50%, making electricity a far more attractive commodity from a pricing standpoint.

Toyota Nissan Honda & Mitsubishi co-operate to promote plug-in cars

Four of Japan's leading carmakers, including Toyota, today announced a plan to expand sales of next-generation green vehicles by co-operating on the development of electric charging stations.

Toyota, along with Nissan, Honda and Mitsubishi, said there is a critical need to develop an infrastructure in Japan for vehicles that can be charged from a power point, such as plug-in hybrids and electric cars.

The carmakers said they will work with the Japanese Government to more than double the number of charging outlets to at least 4,000 quick chargers and 8,000 regular chargers.

They said an expanded charging network would maximise the electric-only driving performance and combined fuel economy of plug-in hybrids.

It would also enable motorists to extend the driving range of electric vehicles, which do not produce any tailpipe emissions.

Normal chargers would be installed in commercial facilities such as large shopping malls or highway service areas where motorists typically stopped for long periods.

Quick chargers would be installed for shorter-duration stops such as highway parking areas, convenience stores and fuel stations.

The carmakers will temporarily bear part of the installation and maintenance costs that are not covered by government subsidies of 100.5 billion yen ($1.1 billion) announced for 2013-14.

Their co-operation is based on an understanding that the charging infrastructure has public value and enhancing it should be done quickly during the limited period the subsidies are available.

The collaboration extends to car owners being able to use the same credit card for payment at all charging stations.

The Japanese government would like to see sales of these next-generation cars accounting for 15-20 per cent of new-car sales in 2020.

The four carmakers are committed to developing a more user-friendly charging infrastructure and to contributing to a society making maximum use of electric-powered vehicles.

Engadget Test Drive the Spark EV [VIDEO]

Engadget got to test drive the The Spark EV, GM's first pure electric car since the company scrapped the EV1 program in 2002.

Performance is quite impressive for an EV this size: it sprints to 60mph in just 7.6 seconds with a top speed of 90mph. The 21kWh nano-phosphate Li-ion battery pack is liquid cooled / heated and is located in the floor. It offers a range of up to 82 miles and takes less than seven hours to fully charge using a level 2 (240V) charging station. Better yet, with a DC fast-charging option coming to the Spark EV later this year, you'll be able to charge the battery to 80% capacity in just 20 minutes.

Chevy's managed to keep the weight down to 2967lbs, which is pretty svelte for a pure electric car. This, combined a low center of gravity and a close to 50/50 weight distribution makes the Spark EV nimble and fun to drive.

Electric cars enjoyed one of the best months of sales to-date

Sales of electric cars are really starting to gain traction. Just in the month of June of this year, almost 9,000 plug-in electric vehicles have been sold in the U.S. This adds to more than 110,000 plug-in electric vehicles that have been sold in that country in the last two and a half years, the Electrification Coalition reports.

Tesla has been one of the biggest winners of the growing tide of electric cars, and managed to capture 8.4 percent of the luxury market in the first six months of 2013. Sales of Tesla cars have beaten virtually all of their competitors, including the Mercedes-Benz S-class, the Audi A8, and the BMW 7 series. Those are impressive statistics indeed, and not something we could have predicted even just a couple years ago.

The Nissan Leaf has also had a great deal of success, capturing 3.3 percent of the subcompact market. The Electrification Coalition has also pointed out that electric cars have not only the awards from various automotive publications, but have also enjoyed some of the highest customer-satisfaction ratings of any passenger cars. In addition, the Leaf and the Chevrolet Volt continue to receive high marks from major consumer-ratings publications.
