Toyota experimenting with a plug-in electric Prius
July 31, 2007 Toyota’s Prius was pretty much the mass-market pioneer of hybrid cars and its sales success has demonstrated to the company that a significant sector of the community are willing to pay a premium for a car that’s both exceptionally fuel-efficient and environmentally friendly. Still, it remains a petrol-based car in its current form, using its electric motor mainly to maintain cruising speed and charging it indirectly through the output of the petrol engine. Toyota’s latest announcement could turn that equation on its head – by incorporating bigger, longer-lasting batteries and enabling plug-in overnight charging, they’re experimenting with making the Prius a primarily electric-powered car that only falls back on petrol when it absolutely has to. The changes could give the Prius massive fuel economy if used for short commutes – between 100 and 500 miles per gallon is possible. Although the company’s sticking with old-school nickel-metal hydride batteries instead of the latest lithium-based units ( and it may well only be doing this in response to some smart aftermarket operators) this could be our first glimpse of a mass-market commercial car that runs primarily on batteries, but has all the comfort of petrol to fall back on.

Porsche demonstrates Cayenne SUV hybrid prototype
July 27, 2007 Porsche this week demonstrated a Cayenne SUV hybrid prototype, providing a glimpse of what the company will offer to consumers by the end of the decade. The Cayenne Hybrid features a full-hybrid design where the hybrid module (clutch and electric motor) is positioned between the combustion engine and the transmission. The design will improve acceleration and engine flexibility compared to a conventional Cayenne and Porsche is targeting average fuel consumption figures of 9.8 liters/100 kilometers in the New European Driving Cycle and about 24 miles per gallon in the US FTP cycle for the Cayenne Hybrid, and hopes future developments may allow it to push towards a consumption figure of 8.9 liters/kilometer (approximately 26 miles per gallon). Porsche plans to introduce similar hybrid technology in a version of its Panamera four-door Gran Turismo. The Panamera will debut in 2009, with a hybrid to follow. (read more...)
The first hybrid race win
July 18, 2007 A new era dawned on the weekend when Toyota won the Tokashi 24-Hour Race with its Supra HV-R hybrid race car. It is the first time a hybrid race car has won a competition of any form though the Supra is quite different to roadgoing hybrids as it incorporates a quick-charging capacitor system and the four-wheel energy regeneration is tuned to work efficiently in recovering a large amount of the car’s energy during rapid deceleration. The system uses 10kw in-wheel motors in the front wheels plus a 150 kW rear-axle mounted electric motor. In total, the 1,080 kg Supra has a whopping 700 horsepower (473 bhp from the 4.5 litre petrol motor and 227 bhp from the electric motors). More importantly, the low down grunt afforded by the electric motors along with the ability to measure and modify the additional torque thousands of times per wheel per second make the car far more controllable than a simple petrol engined vehicle … not to mention kinder on tyres, more economical and brutally quick on the exit to corners.

Lightweight, hybrid multifunction fuel cell to lighten soldiers' backpacks
July 5, 2007 Infantry soldiers have a tough lot in life. Apart from being constantly shot at and placed in risk of bodily harm, they're frequently forced to carry around large amounts of heavy equipment, sometimes weighing over a third of their bodyweight. On a typical 5-day-operation, disposable and rechargeable batteries alone account for about ten kilograms of backpack weight, not to mention the various charging devices for cell phones, PDAs and visual systems. There's good news though - German researchers have developed a lightweight hybrid power supply that will soon be able to ease the load. (read more...)

Proton unveils prototype Hybrid Car Developed In Collaboration With Lotus
April 16, 2007 Malaysia’s National auto manufacturer Proton has unveiled its first Hybrid prototype, designed in collaboration with Lotus Engineering. It is just over two decades since the company bolted together its first cars from Mitsubishi parts imported from Japan, but as the company has grown in strength, it has acquired considerable engineering design, development and manufacturing expertise, pulling off a major coup with its acquisition of Lotus in 1996. The 'EVE Hybrid' (Efficient, Viable, Environmental) research and development project was a collaboration of Proton and Lotus and EVE sports some impressive vital statistics. EVE has a 1.6litre petrol engine, which uses a 'micro-hybrid' start-stop system, a full parallel hybrid drive and a continuously variable transmission to achieve fuel economy of 5.6 litres/100km. maximum torque of whopping 233Nm at 1500rpm and maximum power of 105kW at 5500rpm enabling the car to accelerate from 0-100km/h in 9.0 seconds with a top speed of 188.8 km/h.

The three-wheel, 225 mpg plug-in hybrid XR-3 kit car
March 21, 2007 Robert Q. Riley’s radical high-efficiency designs, concepts and kits have been public for a long time, and have often been viewed as non-mainstream and largely irrelevant by an American population with a highly distorted view of the real cost of cheap petrol. Now his fuel-efficient designs seem suddenly relevant – we desperately need new transportation alternatives that conserve energy and protect the planet’s ecosystem, Riley’s latest creation, the XR-3 plug-in hybrid, is a sleek two-passenger, three-wheel sports car that is expected to return 225 miles per gallon. Designed to be assembled by someone with average mechanical abilities and no prior experience, the all-wheel drive vehicle will be available as a kit or plans for complete do-it-yourself construction.

The plug-in hybrid carving three-wheeler from Venture
February 17, 2007 UPDATED IMAGES Venture Vehicles has formally announced in Los Angeles, the development of a revolutionary (not to mention very cool), 3-wheel, tilting, plug-in Hybrid vehicle under the working name VentureOne. It’s a two-passenger Hybrid vehicle that will get 100 mpg, accelerate from 0-60 in 6 seconds, will have a top speed of over 100 mph, while being priced at under US$20,000. In addition to the low-emission, flex-fuel Hybrid model, a zero-emission all-electric version is also being developed that will have an all-electric range of nearly 200 miles. A key feature of the VentureOne is the patented Dynamic Vehicle Control tilting technology from Dutch-based Carver Engineering that allows the body of the vehicle to actually tilt when going through turns while all three wheels maintain firm contact with the road. Carver already sells petrol-engined versions of the machine, and the Phiaro 3-wheeler is also closely based on the Carver. But a plug-in hybrid with a 200 mile electric range and sportscar performance is very enticing. Production is not scheduled until late 2008 and Venture Vehicles will initially offer two propulsion packages for the VentureOne: the hybrid E50 and Q100, and all-electric Venture EV model. The US$23,000 all-electric model will top the range while the E50 hybrid will sell for US$18,000 and the Q100 hybrid is expected to be priced under US$20,000. (read more...)
Volvo starts project with hybrid-drive garbage vehicles

World’s first affordable diesel hybrid powertrain
December 14, 2006 Zytek has already proven its knowledge of powertrains and electric vehicle many times over, on and off the racetrack. Now, in collaboration with a UK Government initiative, the British engineering consultancy has developed a novel diesel hybrid powertrain that will be affordable in the most popular market segments. The new technology will allow vehicle owners to drive across London’s extended congestion charge zone for just four pence. The low-cost, high-efficiency hybrid-electric drivetrain offers a realistic alternative to expensive proprietary systems and can be quickly implemented within the packaging constraints of compact European passenger cars. A demonstration vehicle, built within the UK Government’s Ultra Low Carbon Car Challenge (ULCCC), has exceeded all targets set for the programme, delivering an exceptional 85g of CO2 per km compared with 121g/km for the already exceptionally efficient standard vehicle.

Hybrid Manned/Unmanned Light Helicopter Makes First Flight
October 10, 2006 This photo shows the first of two newly designed A/MH-6X light-turbine helicopters lifting off for the first time late last month at Boeing’s Rotorcraft Systems facility in Mesa, Arizona. The flight was a significant milestone in the continuing development of the versatile hybrid manned/unmanned military aircraft which combines the proven performance of the A/MH-6M Mission Enhanced Little Bird (MELB) with the unmanned aerial vehicle technologies of the Unmanned Little Bird (ULB) Demonstrator, a modified MD 530F civil helicopter that has been in development since 2004. Aircraft performance will be similar to the ULB Demonstrator with an additional 1,000 pounds of payload that can be used for increased range, endurance or mission hardware. Total payload for the ULB Demonstrator is greater than 2,400 pounds. (read more...)
The world’s first commercially-available electric-solar hybrid, and a sporty one at that
October 2, 2006 It’s not often we get lead stories on consecutive days from the same company (never before in fact) but French transportation futurists Venturi have done it again – this time with the first solar electric hybrid to be commercialised in the world. Named Astrolab (latin astro = star, labe = to take) because it takes its energy from the sun in order to move, the solar commuter is capable of working with very little energy (16 kW engine) and of recharging even when in motion, and does not need to be permanently exposed to the sun in order to move. The car’s performance is remarkably close to that of a petrol-engined vehicle as it has a top speed of 120 kmh and a minimum range of 110 km. To attain this level of performance while using very little energy, the Astrolab has been designed like a Formula 1 car with an ultra-light carbon monocoque chassis serving as an oversized protection cell in the event of a collision and at the same time offering a large surface for the 3.6 square metres of photovoltaic cells. Its profile recalls the aqua-dynamic design of great racing yachts and Venturi draws the parallel between Astrolab and a sailboat : both advance silently while making best use of the elements and both offer sensations unlike any other. Its designer Sacha Lakic describes Astrolab as “a flying wing set on four wheels.”Astoundingly, it’s not just a show car - EUR92,000 will buy you one and the first vehicles are scheduled for delivery in January, 2008. Do be sure to see yesterday’s equally remarkable story about the world’s first energy-autonomous vehicle. Venturi, we salute you! (read more...)
NuVinci continuously variable planetary (CVP) technology set for pedal-electric hybrids
September 12, 2006 One of the many inventions with which the extraordinary Leonardo da Vinci is credited is the Continuously Variable Transmission (CVT), a technology that has only just come into common usage 500 years after his foresightedness was committed to parchment. NuVinci is a new highly adaptable and scalable variation on the CVT theme that looks set to make its mark – developed by Fallbrook Technologies, continuously variable planetary (CVP) NuVinci technology promises a practical and economical CVT for both human-powered and motor-powered vehicles and machines. The NuVinci CVP is applicable to any product that uses a transmission, including bicycles, light electric vehicles, agricultural equipment, automobiles and utility class wind turbines and an announcement overnight heralds the first use of the new technology by well-known electric-powered vehicle manufacturer Currie Technologies in hybrid electric bicycles and electric scooters which will combine the NuVinci CVP with the Currie Electro-Drive drive system. The first product will be seen before the end of the year and already looks set to give the pedal-electric hybrid bicycle remarkable new capabilities. (read more...)
International Race Formula for hybrids set for 2007
UPDATED September 4, 2006 Here's one out of left field. Only a week ago we reported on the coming Formula Zero series for fuel cell go karts. Now comes the breaking news from Italy that N.Technology S.p.a. and Tatuus s.r.l. have signed a deal to produce a new single-seater Formula car. Tatuus, which builds Formula Renault cars, will take care of bulding N.Technology’s concept and will also provide technical assistance and spare parts service to the teams involved in the new series. The new single-seater car will have a 2-litre, 4-cylinder, 250-bhp engine, gearbox and clutch controls on the steering wheel and has been conceived to be fitted with an hybrid engine system. N.Technology's Andrea Fiorani reports that the first season for the formula will be the 2007 season. Formula N.T07 cars will compete in a new international series within the European rounds of the FIA World Touring Car Championship. Eurosport will be responsible for the TV production and broadcasting of the events of the international series. That's the first sketch of the Formula N.T07 car which predictably looks a lot like a Formula Renault - more news when it comes to hand, but we must say we're excited at the prospects of creating an environment where creative and higly competitive engineers develop hybrid technology.

The Fhybrid front-wheel driven hydrogen-powered scooter
July 29, 2006 The Fhybrid scooter is a hydrogen electric hybrid two wheeler that has emerged as Crijn Bouman's graduation project at Delft University in Holland and it is a very different form of two wheeler than almost anything that has come before it. For starters, it’s the only front wheel drive two wheeler going around that we know of, has a reverse gear for parking (another first on a scooter), and a range equivalent to that of a normal scooter in that it can travel approximately 200 km on a full tank of hydrogen. Oh, and it doesn’t make any noise or produce harmful emissions and looks very different to normal scooter fare. (read more...)
'Boosted Hybrid' technology offers new approach to lower emissions and performance improvements
July 16, 2006 A new approach to hybrid powertrain design, combining advanced pressure boosting technology with electric torque assist in one compact unit, has been demonstrated to offer a low cost route to lower emissions and performance improvements. The system, called the SuperGen i-Hybrid, is compatible with conventional gasoline powertrain architecture, and is claimed to offer all the benefits of a hybrid transmission at around one third of the cost of a conventional hybrid solution. SuperGen i-Hybrid can be applied to all mainstream gasoline engines and also diesels, acting as a pre-booster. (read more...)
High performance electric-human hybrid bicycle
May 31, 2006 Electric bikes and scooters hold much promise in the future transport equation, particularly for short distance commuting, but one of the limiting factors is their rather sedate speeds and limited range. The Optibike is designed to overcome these obvious deficiencies with a range of 25 to 30 miles (40 to 48 km) and very clever microprocessor-controlled electronics and Shimano XT 7 speed Derailleur gears which enable the motor to be assisted by the rider at all speeds. This means the Optibike will run at 20 mph (32 km/h) on the battery alone, cruise at 25 mph (40km/h) with gentle pedalling and with some aggressive pedal assistance, run with the traffic at 35+ mph (60 km/h). For those who are prepared to settle for a shorter battery life of 30 minutes, the Optibike can have its top speed increased to 46 mph (75 km/h). (read more...)
Scuderi Group Air-Hybrid Engine claimed to double fuel efficiency
May 3, 2006 On March 7, we wrote of the coming of Scuderi Group's Air-Hybrid engine which claims the title of the world's most fuel efficient internal combustion engine. The Scuderi engine makes its European debut May 9 - 11 at the Engine Expo 2006 in Stuttgart, Germany on a bit of a roll. With three additional worldwide patents recently filed, the air-hybrid system potentially doubles the fuel efficiency of today's gasoline and diesel vehicles and reduces toxic emissions by up to 80 percent. The design is ingenious, has been verified by a world renowned independent laboratory, just landed a US$1.2 million DoD grant to develop the technology further, and it was clearly the talk of the Society of Automotive Engineers World Congress in Detroit where it was officially declared the most visited stand. The technology can be adapted for either diesel or gasoline engines of any size and is claimed to halve fuel consumption compared to today’s internal combustion engines. Autoblog has a succinct well-crafted peice and this animation will help you conceptualise this clever twist on the Otto cycle. There's also the official how it works and theory of operation.

General Motors, DaimlerChrysler and BMW premiere two-mode hybrid technology
June 19, 2006 UPDATED with extensive image and diagram library Details of the hybrid drive system under co-development by General Motors, DaimlerChrysler and BMW have been released and the new system is quite a technological feat due to the full integration of electric motors with a fixed-gear transmission. As a result of its low- and high-speed electric continuously variable transmission (ECVT) modes, the system is commonly referred to as the 2-mode hybrid. The system also incorporates four fixed gear ratios for high efficiency and power-handling capabilities. During the two ECVT modes and four fixed gear operations, the hybrid system can use the electric motors for boosting and regenerative braking. Traditional “one-mode” hybrid systems typically have only one torque-splitting arrangement and no fixed mechanical ratios. Due to their less capable mechanical content, one-mode hybrids need to transmit a significant amount of power through an electrical path that is 20 percent less efficient than a mechanical path. Working collaboratively, the group has conceived a full hybrid system featuring four fixed mechanical ratios, within the two ECVT modes, to reduce power transmission through the less efficient electrical path. Consequently, the electric motors are more compact and less dependent on engine size. (read more...)
