Australia’s peak motoring group wants the federal government to limit fuel consumption by Australian-made cars as part of Prime Minister Kevin Rudd’s response to climate change. The Sunday Telegraph newspaper says an NRMA campaign for new engine Read More
The news was not all good, however, as the report found that despite improving their productivity, the Big 3 are still unable to match the Japanese in profit made per vehicle. While Honda and Nissan earned $1,641 per vehicle built in North American last year and Toyota earned $922, Chrysler lost $412 per vehicle and GM and Ford lost $729 and $1,467 per vehicle, respectively. Much of those losses come from high health care costs and profit-shrinking incentives required to move less popular vehicles like trucks and SUVs. The Harbour Report suggests, however, that employee buyouts and those new contracts with the UAW that get them off the hook for retiree health care will improve the Big 3’s profit per vehicle dramatically. Check out the lengthy press release from the Harbour Report after the jump if you’re into digging through the nitty gritty details.

Large pickup trucks and SUV’s have long been the last stronghold for Detroit’s struggling automakers. While the Big 3 still have a commanding lead in sales of these large vehicles, it’s the smaller, more fuel efficient vehicles which are taking the largest bite from the overall market share pie. Record-high fuel prices have put such a damper on truck sales that a shocking five vehicles outsold the F-150 last month, all of them highly practical sedans. It seems easy to see, then, where Detroit should be spending what engineering dollars it has left. [Source: The Detroit News]

Unless you’ve been on planet Nader for the last few years, you knew Chevrolet was brewing up an uber-Vette. Amid all the hype, spy photos, leaked photos (and subsequent prosecutions), rumors, and names (Blue Devil, SS, Sting Ray, Z07), any dolt could discern that this new Corvette had the potential to be amazing. During its annual press preview for the Detroit auto show, GM showed journalists what we’ve all been waiting for; the official, almost-ready-for-production 2009 Corvette ZR1 destined to hit showrooms next September. Tom Wallace, Corvette Chief Engineer, began the presentation by talking about what started the ZR1 program. To our group of gathered reporters, he recounted a meeting that took place more than six years ago when GM Chairman Rick Wagoner asked what a $100,000 Corvette would look and perform like. On cue but out of sight of our pack of writers, a sinister-sounding V-8 fired up. Bob Lutz, GM Vice Chairman, then drove the ZR1 out into the meeting area. After Lutz slid out from behind the wheel, he gave his driving impressions of the ZR1, “What’s so terrific about this car is that it is very docile and easy to drive, but then when you step into it, the power just never stops.” Subsequent presentations explained why. Final specifications are not yet available because the development team is still fine-tuning powertrain and chassis calibrations, but this is what GM told us. The new LS9 engine is a 6.2-liter supercharged and intercooled V-8 that shares key dimensions and some features with the current Z06’s LS7. The “9″ uses a fifth-generation low-profile Eaton supercharger that itself incorporates plenty of new technology. Its impellers sport four veins instead of three, greatly improving volumetric efficiencies while reducing parasitic losses. Compared to the previous generation blower that required approximately 120 horsepower at maximum boost, the new unit draws only 80. Final horsepower numbers will exceed 620 and torque should come in around 600 lb-ft. The rumor mill pegs the target horsepower figure at 650. The top of the supercharger is visible when the hood is closed thanks to a Lexan window placed in the center of the carbon fiber hood. The hood itself eschews big bulges for tasteful lines that tightly envelop the LS9 (compared to previous LS engines, the LS9 is only one inch taller overall, even with the supercharger and intercooler). No Pro-Stock hood scoop necessary. The transmission is a modified version of the Tremec six-speed used in so many high-performance vehicles, including the Viper. In the ZR1, this iteration sports a close-ratio gear set that aids in acceleration. Unlike in the current Corvette where top speed is achieved in fifth gear, an estimated top speed of over 200 mph for the ZR1 will come in sixth. Wallace commented that, “One interior change we had to make was to ditch the standard 200-mph speedometer with a 220-mph unit because this car will so easily exceed 200.” His pride was clearly evident. He added later that this combination is expected to economical enough to avoid the gas-guzzler tax. No specific performance figures were quoted, but Wallace said the ZR1 would easily beat the current Z06’s performance of 3.7 seconds to 60 mph and the current car’s 7:42-second lap time at Nurburgring. One member of the team noted that in its current form, first gear is good for 67 mph, an indication of the new gearing and the LS9’s ability to rev. With so much power comes heat, so the ZR1 has more and bigger coolers and heat exchangers for all powertrain components. A massive front spoiler with an integral splitter helps channel air to all the right places. Side sill extensions are similar to what was used on the C6R racecar. The side vents feature a large strake that bisects the opening. Chassis-wise, Magnetic Ride Control (MRC) is standard. The near instant response of the dampers allows for softer spring rates, and GM claims the ride of the ZR1 is more compliant than the current Z06. Tire size increases at both ends, with 19-inch rims in front and 20-inch rims in the rear sporting 335/25Z/20 Michelin PS2s. Wheel widths are 10 and 12 inches respectively. Brakes discs are huge carbon-ceramic units that are clamped on by six-piston Brembo calipers in front and four-piston units in the rear. The rear discs are as large as the fronts found on other supercars. Metal discs used on the Z06 were provided for comparison on a table-top display, and were considerably heavier. Of course, lighter rotating and unsprung mass is critical for improving every aspect of performance. The Corvette development team took weight out of the ZR1 wherever possible. Carbon fiber is used extensively, even on panels exposed to strong UV light like the roof and roof pillars. (Apparently, UV breaks down the bonding elements within carbon fiber, rendering the material brittle in as little as five years.) GM’s solution is a special clearcoat that costs upwards of $2000/gallon. According to the Harlan Charles, Corvette Product Planner, the ZR1 will be offered in seven colors and offer two wheels (one chrome). The standard ZR1 will feature interior equipment similar to a standard Z06, and there will be one major option package similar to the 4LT that includes the fully leather-wrapped interior. If pricing of 2008 models provides any indication, this RPO will cost around $8,000. Charles also noted that because there is only one set of production tools for the carbon-fiber body panels, yearly production is not expected to exceed 2000 units. Just as the Z06 used the color red to highlight key components, the ZR1 uses blue accents on the LS9 and on the model’s logo. Perhaps this is a tip of the hat to the Blue Devil moniker that surfaced early? GM would neither confirm nor deny. Regardless, this is what a $100,000 Corvette looks like. Wagoner should be quite happy, nod to his past or not.
The Jaguar XKE is also known as the E-Type. It was released in 1961 in a two-seater coupe form. The concept behind it was simple: create a sports car with a great engine and aerodynamic design, and make it look sweet at the same time. The XKE became the trendsetter for sports cars, and has a look that was way ahead of its era. In fact, the XKE was so elegantly designed that even rival Enzo Ferrari made the comment that it is “the most beautiful car ever made.” Back in the 1950s, the Jaguar D-Type was the king of all race cars. It was winning LeMans races almost every year, and with its sexy aerodynamic make, was drooled over by car enthusiasts and ordinary people alike. Sensing the market needed a D-Type that was tamed for the road yet retained that luxurious look and superb performance, Jaguar made the XK-SS. The XK-SS was not received with a popular cheer, yet it wasn’t designed to be widely received. Some has speculated that the XK-SS was a mere ploy, a diversionary tactic Jaguar has used for the real deal. The D-Type was ready to retire from the race tracks, since faster cars were springing up like mushrooms. Still, Jaguar was not ready to give this beauty up into the museum stands–the D-Type was still popular. And so, by tuning down the D-Type’s for-the-race-track design into a sleeker and friendlier look, the E-Type was born. But of course, it wasn’t as simple as that. The XKE went into two test stages: the E1A–which was a top secret, 286hp car reminiscent of the first generation XKEs; and the E2A–a basic remodeling of the D-Type, which was in fact used in a LeMans race. A Classy Road Monster The XKE is both the beauty and the beast. The third series is equipped with Jaguar’s trademark V12 engine. The V12 is a 5.3L, 12-cylinder engine–which means that it could make its competitors eat dust. And to top it all off, the XKE has new suspensions that Jaguar was experimenting with earlier on. The E-Type has independent rear suspensions, employing U-jointed halfshafts to take power from the chassis onto the wheels AND as upper control links. The Jaguar XKE is no doubt an outstanding classic car. With design that encompasses functionality and aesthetics, this classic car is really worthy of being considered as the cream of the crop. And did we forget to tell you that it was the number one car in the top 100 most beautiful cars in the world?

I hope that this article has helped you in some way! You have my permission to use this article for your newsletter or where ever as long as you leave it the way it is.
When you say “super car,” the first things that come to mind are usually either “speed” or “expensive.” With the introduction of Audi’s R8 TDI, that may change to “clean” and “fuel efficient.” The R8 TDI Concept houses a V12 Diesel power plant that is derived from the engine used in the R10 Racecar. The same engine that has twice run the 24-hour Le Mans. It is slightly longer than the traditional V8 used the R8, but much more potent. The Twin-Turbo V12 makes 500 horsepower and 737 ft/lbs of torque, which is available at 1750 RPM. All of this power is routed through a short-throw 6-speed transmission. A small diameter clutch is used to shorten shift times. Also included, as with most Audi’s, is a Quattro all-wheel-drive system. This translates into a 4.2 second 0-62 mph time and a top speed of over 186 mph.
The real story is how cleanly this power is produced. The TDI’s V12 burns clean enough to pass the strict California emissions standards. Strict being an understatement. This is thanks to a new system that requires up to 5 fuel injections for every cycle of the engine. This is paired with a 3-stage exhaust treatment which includes a small injection of a chemical called “AdBlue,” which helps to break down nitric-oxide. The entire system is guaranteed to last the lifetime of the vehicle. As an added bonus, it produces around 24 miles per gallon on the highway, making it one of the most fuel-efficient super cars on the road.
“We are challenging the final piece of conventional wisdom [about diesel engine cars],” said Audi AG Chairman Rupert Stadler. And they couldn’t have chosen a better platform to use. Audi is hoping the R8 TDI will show that a properly engineered diesel engine can maintain a high level of performance while still being good for the environment.

The BMW M3 model family is being upgraded by yet another fascinating player. The new BMW M3 Convertible, the third body version of BMW’s high-performance sports car following the Coupe and Saloon, offers new possibilities to experience uncompromising driving dynamics. Outstanding performance and thrilling dynamics of this kind create the first impression conveyed by the BMW M3 Convertible right from the start: This very special two-door performer not only comes with the same drive technology as the BMW M3 Coupe and the BMW M3 Saloon, but is also a brand-new development from the ground up, again boasting all the features so typical of a BMW M model. The BMW M3 Convertible thus transfers motorsport technology to everyday motoring, meeting even the greatest demands made of such a high-performance car. In its character, therefore, it is first and foremost a BMW M3, while nevertheless betraying its unique identity side-by-side with the Coupe and Saloon.
Creating the interior, the designers and other specialists at BMW M have successfully reached their objective to offer the occupants maximum driving pleasure in an ambience perfectly tailored to their requirements. This applies particularly to the driver’s seat, with all elements required for active motoring being modified accordingly and, through their enhanced functions, reflecting the exceptional power and performance of the BMW M3 Convertible. As soon as the retractable hardtop folds up into the rear compartment, the driver and front passenger enjoy a truly incomparable open-air atmosphere further promoted by the low-slung shoulder line, the seating position moved far to the back, and the short windscreen. The result of this concept, obviously, is an optimum experience of open-air motoring. The frame round the windscreen keeps a generous distance from the heads of the front passengers, allowing the sun and, to a pleasant degree, the wind to flow smoothly into and around the interior. A further highlight is that the occupants now enjoy an even more direct, undiluted experience of the V8 power unit with its unmistakable acoustics. Supreme Performance is the Objective, Sheer Driving Pleasure is the Result Even though the full power and performance of the BMW M3 can only be used on the race track, the car’s impressive supremacy also in city traffic and on country roads ensures sheer driving pleasure in a particularly fascinating rendition. And even that is not all, for there are countless roads and routes the world over which, while being thoroughly enjoyable in the BMW M3 Convertible with the roof closed, offer an even higher level of enjoyment and satisfaction with the roof open in perfect convertible weather. So whoever demands top performance and knows how to enjoy supreme pleasure in life will be thrilled time and again by the new BMW M3 Convertible. —–>www.rsportscars.com
The cost of gas was $.16 a gallon - yes you heard me - $.16 a GALLON! We drove cars that got on a good day 18 miles per gallon and it didn’t break the bank or increase the interest rate on your credit card just to fill up the tank. We would ask mom and dad for a five spot to go cruising up and down the main drag, not the credit card charge of $30 or more that it takes now. It’s no wonder that the old folks (like myself) who are now the parents of children cruisin’ the drag came up with the idea of alternative fuels to try and save ourselves a few bucks at the pump as well as save the planet that we so dearly love and yet manage to almost destroyed the last 30 years or so. One solution to this has been to make engines smaller, cars smaller and sometimes I even wonder if they’ve made people smaller - because I sure can’t fit in these boxes. I actually saw a car that couldn’t have been more than a lawnmower engine with wheels, which were no larger than the ones I used to make my go carts out of when I was (once again) a kid! The car itself was boxy and it did sound a lot like a lawnmower going down the street but hey - I am sure it got great gas mileage! Another solution is to change the gasoline we run our cars on. What does this mean? Well, we remove the lead, an anti-knock agent which was needed in the old days because we didn’t have super computers tuning our cars for us as we drive. We eliminated High octane fuel which to tell the truth pretty much killed a lot of the old muscle cars (Ahh.. the sound of a big V8 in the morning!). and then, we added ethanol (grain alcohol) to the gas to try to thin it out and help it run cleaner. A step in the right direction but personally, I always like my grain alcohol with a twist and just a plash of gin! The other solution we have come up with alternative fuels. So far these consist of been added it to the fuels we’ve reduced or eliminated lead in the fuel which was an anti-knock agent but it did so pollute our atmosphere in which since replaced it with grain alcohol (funny I used to look at that as a kid to drink not to run my car on). The grain alcohol is supposed to reduce emissions while at the same time converting some of the emissions to water vapor that goes into the doesn’t do any good but it doesn’t do as much harm. But this is not the solution. They did have come out with hybrid cars now which run on electricity the last word a combination of gasoline and electricity switching back and forth between the two is the load on the engine dictates. You have to admit this is a pretty smart idea however and makes for a maintenance nightmare because of the weight of the batteries carried in the car cancel out any real advantage of having a hybrid car in the first place. Don’t get me wrong, it does some good just not enough to make a difference. You also have the companies and entrepreneurs that are working on pure electric cars. Unfortunately these haven’t made a big impact on the road right now because it requires so many batteries at the car is incredibly heavy and the batteries and the batteries don’t have a long life in the car so they have to be replaced sooner than any engine overhaul would take place. This is a very expensive ordeal as well as you have to find a specialty shop to that would be able to do it for you. They do have one battery that does show some promise -it’s called the “sulfur battery”. The only problem with this battery is it needs a key element in it out in the field to keep sulfur in its liquid state about 300 plus degrees. Not a good thing to have rumbling around in your trunk! Let’s face it batteries just have not made it to a level or place where they can take to the road as well as a gasoline engine. One of the more exciting things that I’ve seen is called the hydrogen fuel-cell. This unique little device takes water and converts it to electricity by using special layers of chemicals and minerals to separate the hydrogen in the action from each other and causing his chemical reaction that generates electricity between the plates and thereby supplying electricity to whatever needs to be run-in this case the motor in the car. This is probably one of the more exciting developments as come along however it doesn’t create a lot of electricity only creating a few milliamps or a few amps here and there where running cars can take hundreds of amps, especially during hard acceleration. So until they develop this little bit further its out as well. Honestly I believe that at this point in time since we don’t have anything else to run our cars are than gasoline, I believe the hybrid engine is the way to go. But electricity doesn’t really seem the way to go to me and additives to the fuel make it inefficient or simply don’t exist at this time. There has been one promising area that I believe should be pursued… The idea of hydrogen being injected into an engine is a good idea-they actually came up with this some time ago running an engine completely on hydrogen. Do have to admit it was pretty much a rolling firetrap if it ever got into an accident the hydrogen itself is very explosive in very small quantities so great care has to be taken in its care and handling. Now comes the idea I read about. What if one were able to use water as a fuel? It’s plentiful it’s everywhere and it’s a renewable resource. “How is a renewable” you ask? Well it’s car word to runoff water were some component thereof it’s only product coming out of the exhaust pipe would be any guess? Water! The water goes up in the air, and comes down as rain. It’s renewed! It’s a wonderful idea and a few people are working on exactly that idea. Personally, I’m hoping some big corporation picks up on the idea and runs with it. It would be the best possible thing for a planet and face it possible thing for us as a race! Artical Source : GoArticles.com |

The Harbour Report released today reveals that the Big 3 gained major ground in closing the productivity gap with Japanese automakers building vehicles in North America last year. The report found that Chrysler had actually improved enough to tie Toyota as the most productive multi-plant manufacturer on the continent, with both automakers spending an average of 30.37 hours to build a vehicle. The most productive single plant in North America also belongs to Chrysler, as the once experimental Toledo Supplier Park takes just 13.57 labor hours to build a Jeep. For their parts, General Motors plants averaged 32.29 hours per vehicle and Ford plants averaged 33.88 hours per vehicle, both an improvement over last year’s numbers.
