While major U.S. automakers are focusing on hybrid and fuel cell vehicles, Volvo took a different route, unveiling a sports car powered entirely with lithium ion batteries. Volvo is 3CC concept car won Best Design and five Gold Standards at the recent Michelin Challenge Bibendum environmental competition in Shanghai, China.
Not only does the 3CC combine classic Volvo styling cues with exotic gull wing doors and a tapered, 2+1 seating configuration, but it does so with a highly advanced lithium ion battery electric drive train. That is a step apart from the crowd, which these days is largely focused on hybrid and fuel cell concepts, says Ron Cognac, editor and publisher of the Green Car Journal.
Just as the earlier ECC forwarded new thought in hybrid propulsion with its high speed turbine generator design, adds Cognac, today is lithium ion 3CC innovates with its thousands of smallish laptop computer style batteries, which power this zero emission vehicle to impressive levels of efficiency and performance.
Advanced research into sustainable mobility and Volvo engineers have placed particular focus on the conditions regulating safety in small cars and their ability to handle incoming forces in a frontal collision.
The unique aerodynamic styling of Volvo’s 3CC concept car allows room for a third seats in back. The unique ductile design creates room for a third seat in the back, while the batteries are sandwiched into the floor panels.
The 3CC concept car features an 80 kilowatt motor that delivers up to 107 horsepower, it has a potential driving range of 300 km the 3CC has a top speed of over 135 km per hour.
The carbon fiber body is mounted on a steel space frame and composite floor panels, giving the lightweight vehicle the ability to leap to 60 miles per hour in less than 10 seconds. Volvo says the 3CC can travel 180 miles on one charge under ideal driving conditions
The Volvo 3 Cc is safety features include Volvo Safety Ride Down Concept, a unique solution with a seat system that moves forward, a bit like a sled, at the same time as the front is deformed. This movement is slowed with the help of adaptive shock absorbers that tailor the damping effect to suit the collision force and the occupants’ number and weight. The interior can be moved between 0 and 200 mm forward, which has the same overall effect as extending the crumple zone by a corresponding length. It has seats that slide forward at the moment of deformation, the intention being to compensate for the small car’s traditional lack of space in the crumple zone.
Virtual tests showed that the most important part of a ride down system is the energy absorber and that it needs to be adaptive in order to be a viable concept, by responding to differences in occupant load and crash severity.
An environmentally efficient car that also has to be comfortable, enjoyable to drive, attractive to look at and safe to ride is an entirely new approach. The result is the Volvo 3CC, a sporty and appealing, extremely aerodynamic and compact car equipped with an energy efficient electric motor.

CHECK OUT FULL PARIS MOTOR SHOW COVERAGE AT: www.insideline.com TORRANCE, California — Honda on Thursday lifted the veil of secrecy surrounding its new Prius fighter, saying the compact five-door hatchback — christened the Insight — will make its debut on October 2 at the 2008 Paris Auto Show. Honda said the Insight, which will undercut the price of the Toyota Prius, will go on sale in the US next spring. The new Honda Insight is expected to be priced from under $20000 and is the first vehicle in Honda’s ambitious hybrid strategy. In comparison, the 2009 Toyota Prius starts at $22660, including a $660 destination charge. Honda plans to roll out four new gas-electric models over the next four years as part of a broad global strategy to boost hybrid sales to 500000 units by 2012 — which would represent more than 10 percent of its total worldwide annual automobile sales. “Following the launch of the new Insight, Honda also plans to introduce another unique sporty hybrid vehicle based on the CR-Z, first shown at the 2007 Tokyo Motor Show,” the automaker said in a statement. Also in the pipeline is a replacement for the current Civic Hybrid, which is due out in late 2010, and a new hybrid edition of the Honda Fit in 2012. The new Insight is a major leap from the original Insight, a cramped 70-mpg two-seater subcompact that was introduced in December 1999 as America’s first gas-Electric Hybrid Car. Honda took pains in its Thursday announcement to describe the new Insight as …
Gasoline engines have the advantage over diesel in being lighter and able to work at higher rotational speeds and they are the usual choice for fitting in high-performance sports cars. Continuous development of gasoline engines for over a hundred years has produced improvements in efficiency and reduced pollution.
The carburetor was used on nearly all road car engines until the 1980s but it was long realised better control of the fuel/air mixture could be achieved with fuel injection. Indirect fuel injection was first used in aircraft engines from 1909
, in racing car engines from the 1930s, and road cars from the late 1950s.[16] Gasoline Direct Injection (GDI) is now starting to appear in production vehicles such as the 2007 (Mark II) BMW Mini. Exhaust gases are also cleaned up by fitting a catalytic converter into the exhaust system.
Clean air legislation in many of the car industries most important markets has made both catalysts and fuel injection virtually universal fittings. Most modern gasoline engines also are capable of running with up to 15% ethanol mixed into the gasoline – older vehicles may have seals and hoses that can be harmed by ethanol. With a small amount of redesign, gasoline-powered vehicles can run on ethanol concentrations as high as 85%. 100% ethanol is used in some parts of the world (such as Brazil), but vehicles must be started on pure gasoline and switched over to ethanol once the engine is running. Most gasoline engined cars can also run on LPG with the addition of an LPG tank for fuel storage and carburettor modifications to add an LPG mixer. LPG produces fewer toxic emissions and is a popular fuel for fork-lift trucks that have to operate inside buildings.

The hydrogen powered FCHV (Fuel Cell Hybrid Vehicle) was developed by Toyota in 2005 Biofuels Main articles: Biofuel, Ethanol fuel, and biogasoline
Ethanol, other alcohol fuels (biobutanol) and biogasoline have widespread use an automotive fuel. Most alcohols have less energy per liter than gasoline and are usually blended with gasoline. Alcohols are used for a variety of reasons – to increase octane, to improve emissions, and as an alternative to petroleum based fuel, since they can be made from agricultural crops. Brazil’s ethanol program provides about 20% of the nation’s automotive fuel needs, as a result of the mandatory use of E25 blend of gasoline throughout the country, 3 million cars that operate on pure ethanol, and 6 million dual or flexible-fuel vehicles sold since 2003.[17] that run on any mix of ethanol and gasoline. The commercial success of “flex” vehicles, as they are popularly known, have allowed sugarcane based ethanol fuel to achieve a 50% market share of the gasoline market by April 2008.[18][19][20]

The first electric cars were built around 1832, well before internal combustion powered cars appeared.[21] For a period of time electrics were considered superior due to the silent nature of electric motors compared to the very loud noise of the gasoline engine. This advantage was removed with Hiram Percy Maxim’s invention of the muffler in 1897. Thereafter internal combustion powered cars had two critical advantages: 1) long range and 2) high specific energy (far lower weight of petrol fuel versus weight of batteries). The building of battery electric vehicles that could rival internal combustion models had to wait for the introduction of modern semiconductor controls and improved batteries. Because they can deliver a high torque at low revolutions electric cars do not require such a complex drive train and transmission as internal combustion powered cars. Some post-2000 electric car designs such as the Venturi Fétish are able to accelerate from 0-60 mph (96 km/h) in 4.0 seconds with a top speed around 130 mph (210 km/h). Others have a range of 250 miles (400 km) on the United States Environmental Protection Agency (EPA) highway cycle requiring 3-1/2 hours to completely charge.[22] Equivalent fuel efficiency to internal combustion is not well defined but some press reports give it at around 135 miles per US gallon (1.74 L/100 km; 162 mpg-imp).
