Jaguar has unveiled the C-X75 concept, an extendedrange electric vehicle that uses twin gas micro-turbines from Bladon Jets to power two switched reluctance generators from SR Drives. Turbines offer a number of advantages over a reciprocating piston engine when powering range-extending generators, Jaguar says.
80-mile all-electric range. gasoline-powered rangeextender. Composite body with carbonfiber. Preliminary specifications announced today include: 75 MPGe fuel efficiency in all-electric operation. 460 system horsepower (343 kW). 0-60 miles per hour in 5.5 True all-wheel drive (AWD). Automatic braking. Double cab.
Opel also estimates it will reduce the average carbon tailpipe emissions from its fleet by 27% by 2020. GM’s electrified vehicles today include the extended-range electric Chevrolet Volt, Spark EV and Buick LaCrosse, Regal, Chevrolet Malibu and Impala with eAssist. Carbon intensity per vehicle in 2012 was 0.88
Key changes include: Range: BEVs are overwhelmingly more efficient than ICE vehicles due to regenerative braking and more efficient motors. BEVs’ main weakness is range; most midprice BEVs have a limited range of 200 km to 400 km. Much of the drive to lightweight BEVs comes from a desire to extendrange.
The passenger compartment consists of carbonfiber-reinforced plastic, while aluminum is used in the front, rear and room frame. miles) in extendedrange. Click to enlarge. One key to Visio.M’s high energy efficiency is its light weight; without the battery, Visio.M weighs only 450 kg (992 lbs). Body and safety.
Ye Yongming, general manager of Shanghai General Motors, said that the new strategy serves as the planning blueprint for new energy products for 2020—notably battery-electric and extendedrange electric vehicle technologies. The Sail SPRINGO EV is the first example.
Made of carbonfiber and advanced composite materials, Proterra’s unibody design is a prime driver for its high performance with regard to weight and durability. The bus is powered either by an advanced Lithium Titanate fast-charge energy storage pack or an NMC extendedrange energy storage system.
TREV is a rangeextender system that uses a micro-turbine (fueled either by liquid or gaseous fuels) to generate electricity that charges a battery pack. The turbine generator is carried behind the passenger cabin and in front of the rear wheels, making the concept a mid-engined extended-range electric vehicle.
You wont find carbonfiber in the Scout trucks, nor much aluminum. It made decisions to emphasize steel partly based on carbon footprint, he said. If you talk about carbonfiber, its always appealing to be used from a weight optimization perspective, but not from the sustainability perspective.
The Renault gasoline-electric plug-in hybrid system supports 60 km of electric range plus extendedrange due to the gasoline-fueled internal combustion engine. Renault said that the system, which can be carried over to entry-level vehicles, will be incorporated in the range by 2020. Hybrid system.
It combines Mach-E style bodywork with a carbon-fiber tub chassis and components from a current NASCAR Cup Series race car, including suspension, brakes, steering, and wheels, Ford said in a brief statement. That’s in between the 72-kwh Standard Range pack and 91-kwh ExtendedRange pack currently offered in the Mach-E.
The company is also aggressively investing in advanced materials, including nano steels, carbonfiber and resistance spot welding for aluminum structures. Among the development efforts to achieve breakthroughs in battery technology, Akerson noted is an effort that could result in a 100-mile range EV or a 200-mile range EV.
The combination of harvesting whole forests and burning long-sequestered carbon sources such as coal or oil has impaired the Earth’s carbon cycle at an increasing pace. To restore balance we must protect the oxygen-producing biomass of Earth and reduce the amount of carbon emissions. But use of petroleum will continue.
