2011 Chevy Volt one step closer to being rated at 100+ mpg

Sunday, September 28th, 2008 by admin

According to General Motors E-Flex spokesman Rob Peterson, the automaker has reached an agreement with the California Air Resources Board (CARB) that would see the 2011 Chevy Volt get a unique classification different from other current hybrids. This new classification takes into account the fact that the Volt’s 40-mile battery range allows it to complete the bulk of the emissions and economy test procedure without ever running the engine, which would likely give it a mpg rating of 100 mpg or better.

This is problematic for the EPA, which considers dual-power vehicles like the series hybrid Volt no different than a parallel hybrid like the Prius. Currently the EPA is expecting the Volt to complete the test cycle with a charged battery, which means the engine would have to run a lot more and essentially kill the charge sustaining control plan. According to Peterson, GM is still a long way from reaching an agreement with the feds on how to test the Volt, despite what the Detroit Free Press says. However, having CARB consider the Volt essentially an electric car is certainly a bargaining chip in GM’s favor.

Paris Preview: Hyundai goes green blue in Paris

Sunday, September 28th, 2008 by admin

Hyundai is headed to the Paris Motor Show with a bevy of environmentally friendly models and concepts. In addition to bringing along production-intent vehicles like the new i20, Genesis Coupe and Genesis sedan, the automaker will showcase two new concepts that will also carry its blue theme. Remember, blue is the new green. Anyway, the i20 blue features aero tweaks and low rolling-resistance tires in order to improve its efficiency, but it’s the Santa Fe hybrid that’s a bit more interesting. That new model features an electric motor that puts out 30kW of power along with a 2.4-liter four cylinder engine. Both powerplants feed their power through a six-speed automatic transmission with revised gear ratios optimized for fuel savings. A 270V lithium-polymer battery pack sends the juice to the electric motor, and it all adds up to 38 mpg in the U.S. and carbon emissions of 148 g/km. We’ll be in Paris to see these things up close and personal, so stay tuned.

Toyota considers building A-BAT truck, cancels small diesel

Thursday, September 25th, 2008 by admin


Despite the fact that its full-sized truck competitors from Ford, General Motors and Dodge will all offer new small-displacement diesel engines within the next year or so, Toyota has reportedly canceled plans for a similar powertrain for its Tundra. Instead of dumping money into the stalled full-size market, the automaker has reportedly contacted key suppliers for quotes on systems for its radical A-BAT concept truck from the Detroit Auto Show. Powertrain choices for the trucklet would include a traditional four-cylinder option along with a hybrid drivetrain, possibly sourced from the Camry hybrid. If it went into production, the A-BAT would join the lonely Ford Ranger in the small pickup market and would use a uni-body platform in lieu of a full frame, which is standard fare on most other trucks. Then again, it may never be given the green-light for production at all.

Paris Preview: BMW 7 Series ActiveHybrid

Thursday, September 25th, 2008 by admin

With the arrival of the BMW 7 Series ActiveHybrid, which will make its initial debut at the Paris Motor Show, both BMW and Mercedes-Benz are set to enter the luxury hybrid market that has so far only seen action in the form of the Lexus LS600h. Although BMW was one of the brands that helped develop the sophisticated Two-Mode hybrid system that’s currently being used in the full-size ‘utes from both GM and Chrysler, the Bavarian automaker has chosen instead to equip its 7 Series with the same mild hybrid architecture that it helped to develop and is used by cross-country rival Daimler. Like the S400 BlueHYBRID, a 120-volt lithium ion battery will be kept underhood along with a small helper motor that’s hooked up to the engine, in the case of the BMW, a twin-turbocharged, direct injected 4.4-liter V8. Expect well over 400-horsepower from the gas/electric combo along with combined fuel mileage in the low 20’s.

Chrysler LLC debuts Dodge EV, Jeep EV and Chrysler EV

Thursday, September 25th, 2008 by admin

As we learned this morning from Bob Nardelli’s appearance on CNBC, Chrysler LLC is getting into the electric vehicle game and plans to have something on the market by the end of 2010 – the same time GM plans to start selling the 2011 Chevy Volt. The vehicle in question will be one of these three EVs, all of which are powered fully or in part by electrons.

The first and perhaps most exciting is the Dodge EV, which is an all-electric sports car like the Tesla Roadster. In fact, Chrysler seems to have taken a few pages from Tesla’s playbook, which is evident by the fact that its EV is wearing the body of a Lotus Europa at the moment. Lotus also worked with Tesla on the development of its Roadster and is probably offering its expertise in electronics and lightweight vehicle design to any automaker willing to pay for it.

Chrysler says the Dodge EV uses a 200kW or 268 equivalent horsepower electric motor mated to an “advanced lithium-ion battery pack and an integrated power control module”. Peak torque is 480 lb-ft, which helps propel the lightweight Europ… Dodge EV to 60 mph in less than five seconds and a 120 mph top speed. Its range is pegged at between 150 to 200 miles with recharge times of 8 hours for 110-volt outlets and four hours using a 220-volt.

The Jeep EV and Chrysler EV, meanwhile, are both series hybrids like the Chevy Volt, which means they have an electric motor/generator that drives the wheels for distances up to 40 miles before an on-board small displacement engine kicks in to recharge the lithium-ion batteries or provide power directly to the electric motor.

Both vehicles feature an approximate 400-mile range on just 8 gallons of gas, which equates to 50 mpg. The Jeep EV uses an electric motor making 200kW (268 hp) and 295 lb-ft of torque, while the Chrysler EV uses a 190kW (255-hp) motor making 258 lb-ft of torque. However, Chrysler has not mentioned what range-extending gas engines will be used in either vehicle. Its engineers are also exploring in-wheel electric motors for the Jeep EV, which would benefit from being able to control power delivery to each wheel separately while off-roading.

One question you may have is where did Chrysler come up with these three vehicles? The automaker’s in-house ENVI division is responsible for having developed all three under a veil of secrecy for over a year. Today’s announcement, however, was light on details, so it remains to be seen if Chrysler can accomplish its goal of bringing one of these EVs to market by 2011. We see no reason to bet against them, however, as GM has proven what’s possible when a big fire’s been lit under your company’s collective ass.

Are fuel prices hurting acceptance of modern diesels?

Thursday, September 25th, 2008 by admin

Diesel fuel prices are hovering about 20 above gasoline on average. It seems that automakers are a bit worried this disparity could have a negative impact on their upcoming diesel-powered cars and trucks. While it’s true that Volkswagen and Mercedes-Benz are already rolling out new oil-burners in all 50 states with positive results, there remains a concern that there are only so many buyers willing to spend extra to get a more efficient engine and then pay extra to fill it up. At a Senate Energy and Natural Resources Committee on diesel fuel prices today, a spokesperson for the Alliance of Automobile Manufacturers fell short of suggesting what to do about the situation, choosing instead to highlight the fact that diesel fuel is taxed more than gasoline, whereas in Europe where oil-burners are much more popular, the opposite is true. Reading between the lines a bit, it’s not hard to see his point.

Paris Preview: Kia cee’d Hybrid

Thursday, September 25th, 2008 by admin

Kia’s will have at least two new tricks at the Paris Motor Show, one of them being the Kia Soul. The other will be a Kia cee’d gas-electric hybrid. Already available in coupe, 5-door hatch, and sportwagon variants, a hybrid addition based on the five-door would be a perfect addition to the line. So far, the only details we have is that the c’ee hybrid isn’t planned for sale until 2010, when it will join a train of new hybrids from other makers. Kia apparently decided that is when they’ll be able to sell enough of them to make a profit. But we will get the complete scoop on it at next week’s Paris Motor Show, so you won’t have to wait that long.

Senate passes legislation including PHEV tax credits

Thursday, September 25th, 2008 by admin

 

Legislation that includes tax credits for plug-in electric vehicles has passed the Senate. Now the House gets a chance to look things over and put it to a vote. The tax credits allow buyers of PHEVs to receive a credit as high as $7,500 and as low as $2,500 depending on the capacity of the vehicle’s battery. Toyota had raised concerns that the bill focused solely on battery capacity, as its currently announced hybrid plans do not include anything that would approach the maximum credit. In fact, the Chevy Volt sits alone as the only product that has enough battery capacity for the top tier. Chrysler’s recently shown electric vehicles would theoretically qualify if they ever see the light of day.

Once 250,000 qualifying PHEVs are sold, the credits begin to get smaller until they go away completely. At this point, the legislation — and the vehicles — have a long way to go before anybody could actually purchasing a qualifying car, but the framework is now in place.

The gauntlet is thrown: VW Jetta TDI vs. Toyota Prius

Thursday, September 25th, 2008 by admin

Clean diesel or hybrid drive? It’s an intriguing question, and one that’s not quite so easy to answer. There’s the price of diesel fuel to consider, which runs a few dimes over that of regular gasoline. Then there is fuel mileage. Does the Volkswagen Jetta TDI have a shot at dethroning the Toyota Prius as the undisputed mileage champion of the U.S.? To get a preliminary answer to some of these questions, Popular Mechanics put almost 500 miles on both cars, dividing up their miles between the city and the highway. It’s not a knock-out for either car, but it may offer some early answers to a few questions.

First, the mileage. In the city, there’s just no beating a hybrid, which uses its electric motor to good effect and scores over ten mpg better in the stop-and-go traffic of Los Angeles. On the highway, though, the Jetta TDI is able to eke out a narrow victory, scoring less than one mile per gallon better. Once the price of crude is factored in, the Prius remains the overall cheaper car to keep filled up. Of course, there is more to the story than that, including which car is a better to drive — according to PM, the Jetta. Finally, the TDI qualifies for a $1,300 tax credit that the Prius can’t claim. It’s too close to call. Expect a rematch soon enough.

Spawn of Volt: More details on more variants

Saturday, September 20th, 2008 by admin

GM is not going to let the Volt or its E-Flex powertrain get lonely. The first Volt — the one due in late 2010 — hasn’t been finished yet, yet is so popular that GM is publicly theorizing about how far it can spread the technology through the empire. Ideas include a smaller car with a smaller battery pack that could go 20 miles on pure electric, and be much cheaper. A proper wagon, just “a little bit bigger,” could also make the cut.

And those variants don’t all need to be Chevrolets. Other GM brands will certainly be blessed with Volt technology, if not an outright case of brand engineering. Cadillac is one of the wolves thought to be circling the Volt’s henhouse, and using Volt systems in a Caddy might allow GM to make a profit on such a car without tax breaks. If there were a more economical Volt with a shorter electric range, Saturn would seem to be a prime candidate.

It looks like the sole E-Flex powertrain option not planned is an electric-only car, one without a range-extending gasoline engine. GM feels that people would find it too risky to have no backup. But back to that first car, the plain vanilla Chevy Volt that’s still two years away from showrooms – a Volt team member doesn’t appear to have forgotten the prime directive: “You always have to do the first car right and well.” Amen.
