250GP replacement to be unveiled Saturday

The four-stroke replacement for 250cc two-stroke racing will be unveiled at the Grand Prix de France this weekend. It's expected that the class will be replaced by 600cc four-stroke prototypes. The rules will be presented in proposal form, then considered by both the International Race Teams Association and Motorcycle Sport Manufacturers Association and should be finalized June 8 at the Catalunya GP. The new rules could be implemented as early as 2010.

Despite heavy opposition from KTM and Aprilia, it's expected that the rules change will pass. To allow those companies time to adapt (companies who have significantly more experience racing two-strokes than four), it's expected that there will be a one-year moratorium on new teams entering the class, taking effect once the rules are implemented. Check back Saturday for full details.

250GP replaced with four-stroke 625-650cc inline-fours

Dorna unveiled its proposal for a four-stroke replacement for the 250GP class today. If it gets its way, 250cc two-strokes will be replaced by four-strokes of between 625 and 650cc in 2011.The capacity was chosen to protect World Supersport racing. With the aim of keeping costs down, further rules dictate the new engines will be inline-fours, won't have traction control and will use controlled ECUs. Unlike World Supersport, the as yet unnamed new class of GP racing will be exclusively prototype based. No production machines will be allowed.

While the new capacity may sound too close to MotoGP's 800cc limit, the changes are intended to drastically reduce costs. Right now, at about €1million, leasing a 250cc GP bike is only about one-third cheaper than a MotoGP machine. Under the new rules, that cost would drop to less than €100,000. That seems to be the driving reason for these drastic changes, so while we will mourn the loss of yet another two-stroke racing class, we will welcome more accessible, more competitive racing.

Final details of the rule changes will be announced after they are ratified June 7 at the Catalunya GP.

Yamaha's success saling automatic bike in Indonesia influenced other manufacturer to sale the same bike type. After Yamaha Nouvo, Yamaha launch Yamaha Mio which has won Indonesian market and forced Honda and Suzuki to take a role in this class. Honda launched Honda Vario and Suzuki lauched Suzuki Spin and Skywave to compete Yamaha Mio. Then, Yamaha launch Mio Soul and we hear some rumors in recent days that Yamaha will bring their retro bike to Indonesia, Yamaha Vino. People call it Yamaha Mio Vino, yups .. it could be a retro style of Yamaha Mio, not like it's original Vino which has only 50CC capacity, but 125CC.

Honda CS1, Your New City Sport Choice

After being secret for about two monts, finally Honda launch their new motorcycle in Indonesia. This motorcycle has been advertised for about one month, but didn't mentinoned it's name. And finally, 6 April last week, Honda launch it for public in Surabaya. It's name is Honda CS1 (City Sport).

AMG’s Green Initiatives Include Possibility of Diesels, Hybrids, and Turbo V-6s

Mercedes-Benz performance brand AMG shows its environmental side.

Mercedes’s AMG performance division wants to offer guiltless pleasure for those who love performance cars but are tired of being criticized for a lack of commitment to save the planet.

On the eve of the 2008 Geneva auto show, AMG boss Volker Mornhinweg boldly announced that the fleet of performance cars will achieve a 30 percent reduction in carbon dioxide (CO2) emissions by 2012. Smaller engines, hybrid systems, and diesels are all on the table for Mercedes’ thriving performance sub-brand.

Mornhinweg leveled a shot at BMW’s claim to “efficient dynamics” which is spawning products such as the X5 Vision diesel hybrid concept, also unveiled in Geneva. AMG’s roots are in racing, he said, and “racing was always about ‘efficient dynamics,’ we just called it differently.” He then went on to announce fuel-saving technologies to be offered in AMG cars across the globe.

In 2010, direct-injection gasoline engines and start-stop systems will mark the beginning of the push to lower consumption and emissions. AMG is developing a crankshaft starter-generator system that it claims is far more advanced that BMW’s current system, which operates with a conventional starter.

Two-Mode Performance

But that kind of technology is just the beginning. AMG is working on full hybrid cars that can drive short distances with just the electric motor. Mercedes is part of a consortium with General Motors, Chrysler, and BMW in developing this “two-mode” or full hybrid system for use by each automaker.

Mercedes did not want to launch its version of the two-mode system in the M-class, as there already are hybrid SUVs on the market, and “we don’t want to be a follower,” says Mornhinweg. For AMG, look for the technology to bow on a low, sporty car like the CL, the SL, or the CLS.

What’s more, you may be able to get an AMG oil-burner. Mornhinweg: “We are monitoring the diesel. There is currently no demand, but if that changes, we can react immediately.”
The idea would not be new. Five years ago, AMG offered the 228-hp, five-cylinder C30 CDI turbo-diesel, and while it was successful in some Southern European markets, it was loud and generally unloved. AMG had not seriously considered a follow-up model, but that thinking has changed. By the end of 2008, the brand will have decided whether to proceed with a second diesel.

Turbocharged V-6s on Tap?

In a reversal of its strategy of the past few years, AMG could also offer six-cylinder gasoline engines again. This time around, they would be turbocharged. Mornhinweg says that a decision will be made soon. Turbocharged V-8 engines are already high on the agenda.

Despite all that fuel-saving technology, AMG continues to focus on fun and performance. The new MCT multi-clutch transmission—essentially Mercedes’ seven-speed automatic with a multiclutch system replacing the torque converter—will migrate to more models after its debut in the SL63 AMG. The next-generation CLK and SLK are sure bets to receive the gearbox, while the C-class is an open question. It won’t replace the automatic throughout the lineup as it is not well-suited to towing and does not fit the character of the S- or CL-class luxury cars.

AMG will also up its performance credibility with ceramic brakes. By now, they are reliable but cooling is still a challenge, and there needs to be a significant performance advantage over the regular brakes to warrant the additional cost.

AMG is hoping its fuel-saving announcements present a challenge to competitors. Porsche has announced a CO2 reduction of 30 percent for its V-6 hybrid powertrain over the regular V-6. But such savings across the entire fleet are “unrealistic,” Porsche board member Wolfgang Dürheimer tells us here in Geneva.

Last year, AMG sold 20,107 units, its best results ever. For 2008 and beyond, Mornhinweg is aiming for “further, profitable growth.” If he reaches his ambitious CO2 targets, Mother Earth won’t really care.

Meanwhile, Daimler AG is claiming a breakthrough in battery technology, saying it has achieved the Holy Grail of adapting lithium-ion technology for automotive use—crucial to winning the race to offering hybrid, electric, and fuel-cell vehicles. It will be used in the Mercedes S 400 BlueHybrid staring in 2009. The stumbling block had been integrating the power source into the climate control system

2011 Chevrolet Volt Concept

GM checks off milestones in the development of its gasoline-electric plug-in vehicle.

General Motors is developing the Chevrolet Volt electric vehicle and its lithium-ion battery pack on parallel paths—and both have passed significant milestones en route to a targeted November 2010 launch.

Larry Burns, GM vice president of research and development and strategic planning, tells Car and Driver in an interview that the design of the car has been frozen. While the production model is not a twin of the Volt concept, the more conventional sedan bears a family resemblance to the Chevy Malibu. And, in the interests of speed, it dips into parts bins of existing GM products wherever possible. That likely includes an existing four-cylinder gasoline engine as the on-board means of recharging the battery that, alone, gives the vehicle a range of only 40 miles.

The car was designed around the need to package a battery pack with a 150,000-mile life, with enough performance for a 0-to-60 mph time of 8.5 seconds. The Volt concept also underwent changes to improve aerodynamics after extensive wind-tunnel testing.

Time to Hit the Road

And at an event in Detroit, GM execs discussed preparations for road-testing the lithium-ion batteries that will go into the production car—past tests were with nickel-metal hydride batteries. The next stage of testing begins this month, with battery packs in a 2001 Chevy Malibu mule to gather much-needed durability data as the team scrambles to simulate 10 years of usage over the next two.

Burns says initially GM canvassed numerous battery suppliers around the world as part of its e-flex program. After a “bake-off” between suppliers, GM is working with two deemed to “have the chemistries to get there.” Burns says there are eight criteria that GM determined its lithium-ion batteries must meet for automotive application, including such things as energy density, extreme temperature viability, the material set, and cost.

GM has shown a series of concepts with the e-flex propulsion system: the original gasoline-electric Volt concept, a hydrogen-electric Volt, and the Opel Flextreme, which is diesel-electric.
The Volt will qualify as a PZEV (partial zero-emissions vehicle) and there will be an E85 ULEV (ultra-low emissions vehicle), but there are no plans for a diesel, execs said this week.

Second-Gen Work Underway

Meanwhile, Burns says work is already underway on the second generation. He declines to give a timeframe.

Plug-ins may be exciting, but with a range of only 40 miles, they fall short in comparison to a family-size fuel-cell vehicle with a 300-mile range and zero emissions. Burns sees work on plug-ins as a complimentary play to FCVs that convert hydrogen to electricity onboard, with batteries for power assist and to store energy regenerated in braking.

And he doesn’t anticipate the Chevy Tahoe or other full-size vehicles—or even minivans, wagons or mid-size SUVs—will be offered as plug-ins. “It’s okay for a Cobalt-sized vehicle, but not something with twice the mass.” For larger vehicles, GM’s two-mode hybrid system makes more sense. And efficient gasoline engines will continue to play a significant role in the future, Burns says.

GM Determined to be Fuel-Cell Vehicle Leader

And while the Volt program has been designated a number-one priority at GM, fuel-cell-vehicle development is running full steam as well, Burns says, because GM is determined not to repeat with FCVs what happened with hybrids, with Toyota getting so far out in front of the market. “Toyota creamed us on the Prius,” Burns says. “It won’t happen again.”

Audi R8 Sport Under Consideration

Pole-dancing? Audi’s next lightweight supermodel might be a bit more of a stripper.

The Audi R8 is great. But as evidenced by the R8 V-12 TDI (nee R8 TDI Le Mans) concept car on display at this year’s Detroit and Geneva auto shows, Audi is clearly thinking about proliferating the R8 lineup.

The next R8 to roll down the spotless Neckarsulm, Germany, assembly line may be a lightweight stripper version rather than a more powerful oil-burner. So hints Stafan Reil, the head of development for Quattro, GmbH, which assembles the R8 and almost every Audi that starts with “S” and “RS.”

Lighter, more intensified cars make sense for Audi’s sport cars, Reil tells Car and Driver, much like Lamborghini’s success with the lightened Gallardo Superleggera.

“This is a direction you can go and make business,” Reil says, stressing that Audi won’t build anything that won’t make the company money. “It makes sense for the TT, and maybe in the future in an R8.”

A stripped-down-and-juiced-up R8, likely to be called the R8 Sport or R8 Quattro Sport, would adhere to the same ethos as the 2005 TT Quattro Sport, 1000 of which were made in 2005, although none made it to the U.S. The TT Quattro Sport had a more powerful version of the TT’s turbocharged four-cylinder engine, with a stiffer suspension, fewer interior comfort features, and no rear seats or spare tire. Freed from the additional weight, the Sport was able to lop half a second off the 0-to-60 mph sprint. Styling was unique, as was the paint job: all had a black roof over a contrasting body color.
This philosophy would translate well to the R8. Horsepower would rise from 420 to somewhere around 500, we think, with racing seats, fewer speakers, and more carbon fiber throughout the body and chassis. We also expect to see carbon-ceramic brakes and slightly racier bodywork/paintwork. Such a car might be able to hit 60 mph in about 3.5 seconds, given that the “base” R8 does the dash in four flat.

Reil’s comments also suggest a similar treatment is planned for the TT, in addition to the TT-S that debuted in Detroit and the rumored TT-RS. When and where either of these models would be sold is still up in the air. But for our part, we sure hope they can “make business” with them over here
