Cobra MKIV CRS AC Sports Car 4942 cc V8 Engine
AC Cobra MKIV CRS
Cobra MKIV CRS AC Sports Car 4942 cc V8 Engine.
The AC Cobra CRS will use the same five-speed gearbox as the Superblower, together with a Hydratrak limited slip differential, independent front and rear suspension, rack and pinion steering and disc brakes all round (ventilated at the front).
The AC Cobra MKIV CRS is closely related to the AC Superblower (the CRS shares its chassis and a naturally aspirated version of its power unit). Significant weight savings have been made possible on the AC Cobra MKIV CRS through the use of an advanced specification carbon fiber body.

AC 3000ME a Sports Car Coupe Ford V6 engine
The AC 3000ME Prototype was powered by a Ford V6 and clothed in a grp body.The AC 3000ME was first introduced at the 1973 Earls Court Motor Show. It wasn't until 1979 that the first production AC 3000ME's were delivered, and the price had almost tripled since its initial showing. The AC 3000Me continued to be manufactured for six years with production moving to Scotland before the company ran into financial trouble in 1985 and the 3000Me was discontinued.The AC 3000ME was a 2 door, 2 seat, coupe with a mid-engine layout, perimeter steel chassis, 4 wheel independent suspension and superb handling

Toyota PM Concept Car a personal transport concept
Toyota PM Concept Car
Toyota PM is highly maneuverable thanks to its castor like wheels capable of rotating through 180 degrees. The front wheels are also notable because of their hub-less design.
The futuristic Toyota PM concept from 2003 is a personal transport concept.
The PM's cockpit opens by touching one of the unusual stalk mounted headlights, this then glows green to announce the impending opening of the glass canopy.
Another interesting feature Toyota has built into the PM is its adjustable ride height and attitude. As the PM's speed increases it lowers to the ground to increase stability and improve aerodynamics.
Inside the PM information regarding vehicle performance and the location of other PM's is relayed to the single occupant by a floating virtual display.
Power for the concept comes from an electric motor.

Fuel-Cell Vehicles
A fuel cell produces electricity directly from the reaction of hydrogen and oxygen. The only byproduct is water. A fuel-cell vehicle utilizes the electricity produced by the fuel cell to power motors at the vehicle's wheels. Fuel-cell vehicles are similar to battery-electric vehicles in that they are powered by electricity, but they do not have to be recharged like battery vehicles. Fuel-cell vehicles have onboard storage tanks that could be filled at hydrogen filling stations, similar to gasoline vehicle refueling.
What Are the Pros and Cons?Air pollution. Vehicles that run on pure hydrogen are true zero-emission vehicles. Some vehicle manufactures, however, are developing fuel-cell vehicles that can run on hydrocarbons, such as methanol (a liquid fuel derived most commonly from natural gas) or gasoline. Using hydrocarbons to operate fuel-cell vehicles would result in tailpipe air pollutant emissions, reducing fuel cells' overall environmental benefits.
Global-warming pollution. Run on pure hydrogen, fuel cells consume no fossil fuels and emit no heat-trapping gases (which contribute to global warming). However, it is extremely important to factor in any global warming emissions associated with the production of hydrogen. Pure hydrogen gas does not occur in nature in concentrated amounts, meaning that hydrogen must be produced. A number of various technologies exist to extract hydrogen from sources such as water, natural gas, coal, and biomass, among others. The different hydrogen sources and production methods determine the amount of heat-trapping gases and other environmental issues associated with hydrogen production. Advances in hydrogen production are needed to minimize and eliminate global warming emissions. Research needs to continue on producing hydrogen from renewable resources, including wind and solar power and more advanced technologies.
Cost. Today's fuel-cell vehicles are mostly produced as prototypes or in very small quantities. As mass production often correllates to cost competitiveness, current costs are quite high. But the interest of automakers worldwide in developing these vehicles signals their belief that fuel cells will be competitive with conventional-technology vehicles. Increasing experience with advanced hybrid-electric vehicle technology and production will help lower the cost of future fuel-cell vehicles. Hybrid-electric vehicles use electric motors and advanced battery technology, both of which will be beneficial in fuel-cell vehicle development.
Performance and range. As with other electric-drive vehicles, fuel-cell cars are quiet, smooth, and fun to drive. A remaining challenge for fuel-cell vehicle developers is storing hydrogen onboard the vehicle. Because hydrogen is a gas, as opposed to a liquid fuel, a larger volume of it is needed to travel the same distance as with a tank of gasoline. A number of hydrogen storage technologies are being pursued to provide fuel-cell vehicles with a driving range equivalent to today's cars.

Market Availability. Fuel cells have moved remarkably quickly from laboratory to road. Fuel-cell transit bus demonstration projects were completed in both Chicago and Vancouver, and similar demonstrations are occurring in various cities boty nationwide and around the globe. In California, automakers, fuel companies, and government agencies are working in partnership to test fuel-cell vehicle technology and are expected to produce more than 60 demonstration vehicles over the next few years. Also, the California ZEV (Zero Emission Vehicle) Program will require auto manufacturers to sell increasing numbers of zero- emission vehicles over the next decade, further encouraging the development of fuel-cell vehicles. Still, a number of durability, performance, and cost issues must be overcome before fuel-cell vehicles are ready for mass production. Most of the major automakers have stated their intention to begin selling fuel-cell passenger vehicles by the end of the decade.
