Earlier this week, Volkswagen unveiled its Golf Mark VI BlueMotion concept car, which looks set to raise the bar on the fuel efficiency and emissions performance of ‘mainstream’ cars. At just 99g/km, the new hatchback emits exactly the same amount of CO2 as the much smaller Polo BlueMotion. It also undercuts current main rival, the Ford Focus ECOnetic by 16g/km.A new hyper-efficient 1.6 TDI diesel engine also means that the latest offering boasts fuel economy of 74.3mpg (combined), an improvement of around 20% on the Mark V, while still enabling acceleration from 0-60 mph in 11.2 seconds, apparently due to improved aerodynamics and a new ’sporty’ gearbox.
Unique, clever and straight-forward engineering has resulted in three Volvo models ready for the road.
These fuel-sipping marvels feature a 1.6 litre diesel engine along with aerodynamicly reduced air resistance, new Michelin tires that lower rolling resistance, and the new European cyclGearbox with altered ratios for third, fourth and fifth gears. Volvo says the new gearbox configuration alone results in a 1.5% reduction in fuel consumption without affecting the driveability of the car.
According to Businessweek, Ford lists a littany of excuses why they could never market this car in the US. Chief among these excuses is that they don’t think they could ever sell enough of them to make a profit. Ford says that in order to produce them for the US market they’d have to build a new plant and then make at least 350,000 of them a year.
If there’s no way to make a profit on these cars and Americans won’t buy them, why are so many European and Asian car makers bringing these new “clean diesels” to the U.S. starting next year? When I see news that Mercedes, Nissan, Volkswagen and even Honda are all building clean diesel cars with excellent fuel economy for the US market, Ford’s excuses start to seem pretty hollow.
After the last diesel car was taken off the Japanese market in 2007, Nissan Motor Company has become the first domestic automaker to release a diesel car in Japan in six years. And in the current day climate of everyone looking for ways to save on fuel – to cut costs and to help the environment – Nissan’s X-Trail 20GT sport utility vehicle is also the world’s first “clean” diesel.
Being powered by an engine lead-developed by partner Renault SA, the “clean” diesel refers to the fact that the X-Trail meets Japan’s new emissions standards that are set to kick into effect October 2009. These standards are said to be the strictest in the world.
Ok, so it isn’t flashy, just nice clean lines and a monster under the hood. It’s the new Trident Iceni, a two-seat sports car boasting a 6.61 litre V8 turbo diesel from GM that will launch you from 0 to 60 in 3.7 seconds. The company, Trident Performance Vehicles based in the UK, says computer calculations suggest a top speed of 230 mph, and a range of approximately 1000 miles.
The car’s chassis is stainless steel throughout, forming what the company says is a complete safety cell around the occupants against front and side impact. Rollover protection is supplied by a central spine configuration that is said to have the highest torsional rigidity of any car tested. Trident guarantees the car for life against corrosion.
Japan will look to introduce incentives for the fiscal year starting July 2009, for consumers looking to buy clean diesel cars, in an attempt to reduce the countries carbon dioxide emissions. Such an incentive will hopefully not only push consumers into buying cleaner cars, but hopefully push manufacturers into building them as well.
According to an official from the Ministry of Economy, Trade and Industry (METI), further details will be clarified and confirmed over the rest of 2008, for a hopeful introduction in April of 09.
VW made the announcement earlier in the week after receiving notification from the IRS that clean diesels would meet the “Advanced Lean Burn” motor vehicle income tax credit.
Enova Systems and IC Corporation have delivered a plug-in hybrid diesel electric bus to Denali National Park for use in carting visitors around the pristine wilderness.
The bus (similar to the one pictured above) has a GVWR of 27,500 pounds, carries up to 38 passengers and uses up to 70% less fuel than a similarly equipped conventional bus — so if the bus got 10 mpg with a conventional engine, it could get 30 mpg using Enova’s hybrid system.
Automakers and engine manufacturers have been requesting a finished blend specification for B20 biodiesel blends for several years, with some citing the need for that spec as the single greatest hurdle preventing their full-scale acceptance of B20 use in their diesel vehicles.
On June 19th, after more than five years of research and discussion, the American Society for Testing and Materials (ASTM) finally approved the following specifications for biodiesel fuel:
VW announced the pricing of the 2009 Jetta and SportWagen yesterday, along with a new fuel economy certification from the third-party certifier AMCI. It seems that VW wasn’t particularly impressed with the EPA’s 29 mpg city / 40 mpg hwy estimation, and wanted a second opinion.
There has been some general confusion circulating about fuel economy estimates for the new Jetta (which will be available in August) ever since VW’s Director of Powertrain Development announced the car could get up to 60 mpg.
