GM Still Committed to Launching Light-Duty Duramax Diesel

Even in light of tumbling truck sales and the disastrous economy, GM remains committed to get its 4.5-liter light-duty Duramax diesel to market.

GM remains the last truck maker with plans to produce a light-duty diesel. Chrysler has said that its Cummins-sourced light diesel won’t be available until at least 2011, while both Ford and Toyota shelved their plans for a light-duty diesel indefinitely.

A GM powertrain spokeswoman told PickupTrucks.com that GM is still going to produce the 4.5-liter diesel V-8 for use in its Chevrolet Silverado and GMC Sierra half-ton pickups. Even so, GM vice-chairman Bob Lutz is has his reservations on the timing. Lutz claims customers won’t opt for the diesel with gas prices down and diesel remaining higher than gasoline. He says that even with improved fuel economy, buyers won’t see a price advantage in buying the diesel.

The engine being fought over may be one of the most significant leaps in diesel engine design since Rudolf Diesel invented the engine. The engine exhaust exits into the V of the engine allowing the exhaust to spin the turbo more efficiently and quickly. This reduces exhaust back pressure and heat losses allowing the engine to run more efficiently. In addition to increasing fuel economy, this design also eliminates several expensive components, simplifying the engine and reducing the normal price premium seen on diesels when compared to gasoline counterparts.

The most expensive and fastest car in the world: Bugatti Veyron

Model Bugatti Veyron 16.4
Top speed 253mph
Price £810,345
Engine 7993cc, 16 cylinders in a W
Power 1001bhp @ 6000rpm
Torque 922 lb ft @ 2200rpm
Transmission 7-speed DSG, manual and auto
Fuel 11.7mpg (combined)
CO2 574g/km
Acceleration 0-62mph: 2.5sec
Rating Five stars
Verdict Deserves 12 stars. Simply as good — and as fast — as it gets

When you push a car past 180mph, the world starts to get awfully fizzy and a little bit frightening. When you go past 200mph it actually becomes blurred. Almost like you’re trapped in an early Queen pop video. At this sort of speed the tyres and the suspension are reacting to events that happened some time ago, and they have not finished reacting before they’re being asked to do something else. The result is a terrifying vibration that rattles your optical nerves, causing double vision. This is not good when you’re covering 300ft a second.

Happily, stopping distances become irrelevant because you won’t see the obstacle in the first place. By the time you know it was there, you’ll have gone through the windscreen, through the Pearly Gates and be half way across God’s breakfast table.

It has always been thus. When Louis Rigolly broke the 100mph barrier in his Gobron in 1904, the vibration would have been terrifying. And I dare say that driving an E-type at 150mph in 1966 must have been a bit sporty as well.

The car represents the latest interpretation of a theme that has seen such classics as the 250 GT, the 275 GTB, and the 365 GTB4. The Ferrari 599 GTB replaces the 575M Maranello, which followed the 550 Maranello introduced in 1996.

The 599 shares a basic design language and much of its chassis with the 612 Scaglietti. Bodywork was penned by Italian design house Pininfarina. Dynamically adjustable MagneRide suspension enables the 599 to offer a smooth ride for cruising, while still taking corners like a track-oriented supercar.

Lamborghini Murcielago ranked no.1 out of 7 exotic cars.

Lamborghini Murcielago Ranked No.1 in Exotic Sports Cars
Based on analysis of 7 Murcielago reviews and test drives.

MSRP: $354,000 - $382,400
Invoice: NA
MPG: 8 City / 13 Hwy
The 2009 Lamborghini Murcielago ranks 1 out of 7 Exotic Sports Cars. This ranking is based on our analysis of 7 published reviews and test drives of the Lamborghini Murcielago, and our analysis of reliability and safety data.

The Lamborghini Murcielago flies like a bat out of hell. While other supercars may offer more comfortable accommodations, few can match its lustful design and superior performance dynamics.








Introduced in 2001, the Murcielago LP640 is the successor to Lamborghini's much celebrated Diablo. It is named for a legendary nineteenth-century Spanish bull that withstood an unprecedented 24 thrusts of a matador's sword. True to its namesake, the Murcielago combines a muscular and aggressive design with knock'em dead performance capabilities. "Snake-belly low and reverse-cowgirl sexy, this car ... is the most heinously irresponsible, developmentally arrested, awesomely cool sports car the world has ever known," writes the Los Angeles Times. "This $405,000 hypercar is, in short, a great big booger flicked in the face of respectability." Indeed, the Murcielago's 631-horsepower V12 engine wasn't engineered for the faint of heart.

If you're in the market for an exotic supercar, be sure to add the Ferrari F430 to your short list. While the Murcielago is more aggressively styled, the F430's Formula 1 inspired race technology makes it hard to ignore -- especially the high-powered Scuderia trim. For even greater sports performance, the Ferrari 612 Scaglietti makes a great choice. However, its subdued styling cues may not appeal to drivers seeking to flaunt their vehicle's wild abilities.

The 2009 Murcielago is available in two body styles, coupe and roadster.
