Even though hybrids and EVs are all the rage these days, a study by the Boston Consulting Group found that most automakers will be able to meet 2020 EPA emissions targets using gasoline engines that will be 40% more fuel efficient than the current powerplants. Advances in technology concerning engine downsizing, turbocharging, direct fuel injection, more efficient cooling, electric power steering and variable valve timing will help achieve this, according to the 23-page study.
In a decade where green has become the new buzzword for almost every industry, automakers are facing two big problems: economy and emissions. The simplest way to achieve this is to reduce weight and reduce the size of the engine. With all the government mandated safety equipment and luxury features that today’s customers demand - power everything, air conditioning and the like - achieving the former is very difficult. And fitting a small engine into a heavy body is only going to stunt performance and make fuel economy all the more worse.
Fortunately, there are a few potential solutions. Carbon fibre is one. It’s said to be ten times stronger than steel and five times lighter. Unfortunately, it’s also four times as expensive, making it impractical for use in non-luxury vehicles. Now, engineers are looking to green energy and new manufacturing methods to make carbon fibre cheaper. Still, the results are yet to be seen.
The Parisian government’s self-hire electric car program Autolib’ is staring down a legal challenge from the nation’s more traditional car rental agencies, among them Avis and Hertz. According to British daily newspaper The Independent, these “self serve” Bollore EVs cost as little as €5 (£4.40) for a 30 minute journey and are modeled on the French capital’s highly successful Vélib’ bike hire operation. Some 700 four-seat Autolib’ vehicles will be rolled out from December of this year, offering green motoring for both residents and tourists alike. The Italian-built four seaters come with a 250 km battery range, radio and GPS navigation system.
Here’s an innovative idea from Finnish designer Antti Eskeli: a four-seat luxury sedan concept with a “changeable chassis length”, making it as compact as a small hatchback for city driving. So what if the foldable car is nothing new; I’d wager one’s never looked as good as Eskeli’s Maininki concept. 
It’s just one of many entries into the 2011 Michelin Challenge Design Showcase we’ve reported on previously. There is something surprisingly masculine about Eskeli’s fluid, organic design; like cavorting dolphins or an Antarctic glacier.
The latest news from Honda’s motorsport front is that the Japanese company will campaign a CR-Z hybrid racecar at the second annual Le Mans Vers Le Futur (literally translates to ‘Le Mans to the Future’), which is a support event for the 79th running of the 24 Hours of Le Mans. Nissan will also participate in the exhibition, which is devoted to showcasing the Le Mans racing cars of the future, with the pure-electric Leaf Nismo RC concept.
Internet and software bigwig Google has begun lobbying the state of Nevada to legalize driverless cars. The move comes on the heels of some very promising results in California, where Google had mapped out the terrain and sent a couple of its autonomous Toyota Priuses (Prii? Priora?) on an epic jaunt from Mountain View to Santa Monica. The California-based company is keen to point out the claimed benefits of self-driving cars over their human-driven counterparts including better safety, improved fuel efficient and greater environmental friendliness.
On January 30th, 2011, three Mercedes-Benz B-Class F-Cell models set out from Germany to travel around the globe covering 30,000 kilometers (about 18,700 miles) in 125 days to demonstrate the technical maturity and reliability of the world’s first series production fuel cell vehicle.
Toyota and Honda celebrated today the opening of the first hydrogen station in the U.S. fueled directly from an industrial hydrogen pipeline. Located near the headquarters of Toyota USA, in Torrance, California, the station is built on the company's land and is the result of a collaboration between Shell, Toyota, Air Products, South Coast Air Quality Management District (SCAQMD) and the Department of Energy. The station will provide hydrogen for the Toyota fuel cell hybrid demonstration program vehicles, as well as other manufacturers' fuel cell cars in the Los Angeles area.
Congestion and air pollution are killing the world’s major cities. Among them: New York, Beijing, Tokyo, Mumbai and London to name a few. And if you believe the most skewed of environmentalist hype, it’s all down to personal transport. Only it’s not. The UK’s Health Effects Institute (HEI) recently released details of a study called the, “The Impact of the Congestion Charging Scheme on Air Quality in London,” that shows that things may not be as clear-cut as some of us thought. 
Led by Professor Frank Kelly of King’s College London, the study (as the title suggests) investigated what affect London’s much-derided Congestion Charging Scheme has had on the city’s air quality. The result: not much. Through the use of emissions / exposure modeling, analysis of air monitoring data and the, “assay for the oxidative potential of particulate matter,” Professor Kelly and his colleagues found:“From their comparison of actual air pollutant measurements within the CCZ with those at control sites in Outer London, the investigators reported little evidence of CCS-related changes in pollutant levels at roadside monitoring sites, where their modeling had suggested the most pronounced effects would be seen.”
