Audi refers to its new V12 TDI turbodiesel as "majestic", but somehow, that word fails to adequately describe the company's latest oilburner. Grammy-winning singer Seal was on hand to belt out his hit "Crazy", and that term more accurately describes a 6L diesel that makes 500 HP and 737 lb-ft of the twisty stuff (that latter number is maintained in the useful range of 1800- 3000 RPM). This is accomplished via a pair of variable-vane turbochargers that apply 1.6 bar (24 PSI) of squeeze to the intercooled intake charge, and a direct injection system which employs piezoelectric injectors to spray fuel - including multiple pre- and post-combustion events - at a mind-boggling 2000 bar (30,000 PSI). A compression ratio of 16:1 and heavy use of exhaust gas circulation also help keep down the emissions, which meet the 2010 Euro-5 standard.

All that power is fed to an all-wheel-drive system that maintains a 40:60 front-rear balance to maintain what Audi refers to as "slightly tail-heavy, sporty handling characteristics. To slow nearly three tons of mass moving at superlegal velocities, a set of monstrous disc brakes are fitted (the diameter is unspecified, but the fronts appear to be somewhere north of 15"). The concept also carries an interior trimmed in impractical white leather and light-colored carbon fiber.

No word as to when it might be produced, which is just as well since we won't be able to afford it.

The press release is posted after the jump, and we've placed photos (live and stock) here.

Once again Texas will play host to a major truck announcement. On Sept. 28th, Ford will unveil its new 2008 F-Series Super Duty pickup and new 6.4-liter Power Stroke diesel at the State Fair of Texas in Dallas. The big news is that the new Power Stroke will be able to run on Ultra Low Sulfur Fuel, the sale of which will be mandated nationwide as of this October. The engine is larger in displacement than the perpetually plagued 6.0-liter unit it replaces and features some high-tech trickery to achieve particulate emissions levels that equal those of gas-powered engines. The most significant is the use of piezo-electric injectors in the common-rail fuel injection system, a first for a pickup engine sold in the U.S. Ford won't reveal the Super Duty's price or the Power Stroke's fuel economy and power figures until closer to the vehicle's launch in Dallas.
