Solar Cars improve the breed

A famous quote from Soichiro Honda, the legendary founder of Honda Motor Company, says “Racing improves the breed”. There's no doubt many Formula One teams have used the phrase to imply a legitimate link between innovations made in racing that eventually benefit us all as the technology from top-level motorsport filters down into road cars, although it would be hard to convince anyone of a practical use for an off-throttle blown diffuser in a hatch back.

Likewise solar racing cars have made significant contributions that have lead to today's current crop of mass produced Plug-In electric cars. It all started with the winning vehicle of the very first World Solar Challenge in 1987. GM's Sunrayer was designed by Hughes Aerospace, (the company originally founded by Howard Hughes) at the time a division of General Motors, in collaboration with a smaller aerospace company called AeroVironment.

More than a dozen Caltech graduates participated in Sunrayer programs at AeroVironment, the most deeply involved was Alan Cocconi who was responsible for the power electronics systems. This included everything from motor controller through battery management to telemetry.

The Cocconi designed MOSFET based three phase AC motor drive inverter ran a 92% efficient 10 hp (peak) motor that drove the left rear wheel of Sunraycer via a cogged belt.

Sunraycer won Pole with a top speed of 109 km/h and lead the 24 car field from start to finish covering the 3,005 km route at an average speed of 66.9 km/h (41.6 mph), 50% faster than 2nd place.

Following the World Solar Challenge success, in early 1988 GM insiders proposed the idea of making a very efficient EV with the knowledge gained from Sunraycer but to make it an affordable car with decent range and performance equal to a petrol powered car. Work soon begins at AeroVironment on the 'Impact' based around a 15 kWh Lead Acid battery pack, Al Cocconi again responsible for power electronics design.

The Impact EV concept car was launched at the LA Auto Show in Jan 1990 and the car so well received that by April GM announced the car would go into production. The Alan Cocconi designed motor controller for the Impact, a direct descendant of that used in Sunraycer, were refined by Hughes Electronics and went into the GM EV1 when production started in 1996.

Based on his work to date, in 1992 Alan Cocconi founded AC Propusion to produce electric vehicle drive systems featuring high performance, high efficiency induction motors and integrated high power battery charging. The original test bed was a not too glamorous Honda Civic but once the powertrain design was debugged, a Piontek Sportech kit car chassis, originally designed for a Suzuki GSX-R motor, was converted into an EV sports car called t-zero.

Launched in 1997, the 1040 kg t-zero, powered by 28x lead acid batteries, started to make headlines with it's 0 to 100 km/h in 4 seconds levels of performance. By 2003 the car had been upgraded with 6,800x 16850 Li-ion cells with a single charge range of 480 km, a 320 kg reduction in kerb weight and 0-60 times reduced to a supercar beating 3.2 seconds.

If some of these specs sound similar to the Tesla Roadster, that's because the Roadster was developed by Tesla Motors to mass-produce AC propulsions t-zero, the first EV to demonstrate the performance and range potential of lithium ion batteries and the car that can legitimately be credited with inspiring today's mass produced plug-In electrics from GM, Nissan, Mitsubishi etc. In fact Tesla Motors was founded to commercialise Alan Cocconi's work and the Tesla Model S uses technology licensed from AC Propulsion.

Today's solar racers are still blazing a trail years ahead of the automotive industry, witness BMWs i3 Electric car, the first all carbon fibre production car. In the area of powertrains, every WSC winner since 1999 has used direct drive in-wheel motors (road car in-wheel motors are currently being developed) and surely in won't be much longer before the 12.5% of Australian homes that have roof-top PV systems installed realise they already have the infrastructure in place to solar power a plug-in electric vehicle for their daily commute?

All consortium members are driven by a motivation to make this innovative project a success.”

Patrice Ratti, CEO of Renault Sport Technologies, said: “As a global leader for the production of electric vehicles and with a unique expertise in motorsports ever since the company was founded, the choice of Renault as technical partner to develop the fully-electric SRT_01E car for the FIA Formula E championship was obvious. Renault engineers and motorsport experts are directly contributing to the overall powertrain architecture and are in charge of electric systems' specifications and integration, benefiting from the experience acquired while developing the new 2014 Renault-Energy-F1 Power Unit. Renault is also working with Spark to enhance the performance and safety level of the SRT_01E car powertrain. The objective is to design an outstanding race car that will be clean, reliable, safe as well as fast and responsive.”

Peter van Manen, Managing Director of McLaren Electronic Systems, said: “These cars are going to be brilliant racing through the centres of cities. Electric motors deliver instant torque and acceleration and that is what McLaren is all about. Performance and efficiency. Our electric motor, developed originally for the McLaren P1™, has the highest power-to-weight ratio in the world. McLaren is proud to provide the performance behind Formula E.”

Sir Frank Williams, Founder and Team Principal of Williams, commented; "Motorsport is moving towards a greener future and the FIA Formula E Championship will be a prime opportunity to showcase the latest green technology that has its origins in motor racing.

VW announce plans to electrify 14 models by 2014 possibly up to 40

Amazing how some companies change their tune. Only as recently as 2009 Dr Winterkorn himself said that EVs won't have a majority share in the market for another 15-20 years. Yet within 5 years they're planning a total of 14 models from several Group brands with electric or hybrid drive technology. If there is sufficient demand, Dr Winterkorn says up to 40 new models could be fitted with alternative drivetrains.

The Volkswagen Group has set its sights on global market leadership in electric mobility. "We are starting at exactly the right time. We are electrifying all vehicle classes, and therefore have everything we need to make the Volkswagen Group the top automaker in all respects, including electric mobility, by 2018", Prof. Dr. Martin Winterkorn, CEO of Volkswagen Aktiengesellschaft, said on the eve of the 65th International Motor Show in Frankfurt am Main.

Winterkorn is convinced that Volkswagen is strongly positioned: "We have the most comprehensive approach to tomorrow's mobility. From highly-efficient, eco-friendly diesel, gasoline and natural gas-fuelled engines to classical hybrids, purely battery-driven vehicles and plug-in hybrids - no other automaker can match the broad range we have to offer." The company wants to win new customers with electric vehicles that are technically mature, practical in everyday use, safe and affordable, and is showcasing models such as the all-electric e-up! and e-Golf as well as the Audi A3 e-tron plug-in hybrid and the Porsche Panamera S E-Hybrid, also a plug-in model, at the auto industry’s leading motor show.

According to Winterkorn: "The electric car cannot be a compromise on wheels, it must convince customers in every respect." He said that environmental compatibility and sustainability were increasingly becoming the main purchasing criterion: "From the zero-emission city car, through the plug-in hybrid all-rounder to the three-liter sports saloon: It is our customers who decide for themselves just how much e-mobility they want." He went on to say that electric-drive vehicles were a key building block for achieving the ambitious climate protection targets, and that the plug-in hybrid had the greatest market potential.

Initially, a total of 14 models from several Group brands will be available with electric or hybrid drive technology by 2014. If there is sufficient demand, up to 40 new models could be fitted with alternative drivetrains. Winterkorn underscored that Volkswagen had placed electric mobility "at the center of the Group": "We have developed the know-how for electric motors and battery systems at our own components plants, we have recruited 400 top experts for electric traction and qualified almost 70,000 development, production and service employees in this new technology – the biggest electrification training program in our industry."

The Volkswagen Group invests over seven billion euros in research and development each year. A significant share is spent on developing technologies and components for electric mobility – more than in any other field.

The key to rolling out electric mobility swiftly and efficiently across all brands and vehicle classes is the modular toolkit systems which from the start have been designed for assembling electric drives. Production in Bratislava, Puebla, Wolfsburg, Leipzig or Ingolstadt can now respond flexibly and at low risk to demand as it arises and can reduce both weight and costs through the use of proven components.

According to Winterkorn, anyone who genuinely takes ecological responsibility seriously goes one step further: "We must have a holistic mindset and a comprehensive approach to mobility – from generating energy through development, production, retail and vehicle operation right down to recycling. Our clear goal, therefore, is to lead with holistic, modern mobility concepts."

In Europe, Volkswagen Group brands currently offer 420 model variants with maximum CO2 emissions of 130 grams per kilometer, 302 models emitting a maximum of 120 g/km, 50 models emitting up to 100 g/km and 23 models emitting 95 g/km or less. The Volkswagen XL1 plug-in hybrid has the lowest emissions. The world's most efficient series production vehicle has CO2 emissions of 21 g/km, consumes 0.9 liters of fuel and has a range of 500 kilometers, making it the company's technological spearhead.

Vauxhall Cut Ampera Price by £3500

Vauxhall Ampera prices have been cut by £3500, dropping the entry-level price for the innovative petrol-electric range-extender to £28,750, after a £5000 government grant.

Vauxhall/Opel CEO Dr. Karl-Thomas Neumann denied claims that Ampera prices had been slashed because sales were slow. He said: 'The Ampera has sold more than 5000 units and accounts for more than half electric car sales in Europe. That’s disappointing for the electric car market, not for the Ampera.'

The revolutionary plug-in electric car has struggled to fulfil its sales promise, partly because the recession has deterred buyers from adopting less-conventional technology.

Neumann went on to say that GM is 'still convinced that the range-extender is the best electric car concept'. The system works by relying on a standard combustion engine to generate energy for the electric motors that power the car, resulting in a pure-electric range of up to 50 miles and a total touring range of 300 miles with use of the petrol engine.

GM vice-president Steve Girsky also said that the range-extender technology would continue to be used, but that new models with the powertrain were unlikely to happen until 'the technology has advanced a bit further and come down in price'.
