Ford has been touting Ecoboost as an economical alternative to hybrid technology, and word from Automotive News is that the price tag could be $700 per vehicle. Ecoboost is said to deliver 20-30% fuel economy gains by combining turbochargers and direct injection technology with down-sized engines. The automaker also estimates that owners will pay off their Ecoboost premium in two year's time at $3.25 per gallon gasoline and 15,000 miles of driving per year. Since $3.25 is at the optimistic end o

There is awesomeness to the prefix "twin-turbo." It could be a Briggs & Stratton Vanguard engine (awesome in its own right) that you're talking about, but prepending any engine designation with the modifier "twin-turbo" can suck all of the air out of a room. Owners of lesser cars just nod in acknowledgment of their inferiority. Audi fans have lamented the evolution of the S4 from a twin-turbocharged V6 in the B5 version to V8 power for the two most recent iterations. Many feel that the V8 po

One sports car that really needs more power is the Chevrolet C6 Corvette Z06, right? The LS7 engine puts out 505 horsepower in stock form, so it could really use about twice that. Thankfully the folks at APS (Air Power Systems) developed a twin turbocharger kit for the C6 Z06 application. APS claims their power adders will get the LS7 generating upwards of 1100 rear wheel horsepower. Now, knowing the compression ratio of the LS7, the upper reaches of that power range will not be seen by anyone r

We see a lot of rumors here at Autoblog, but this one just has to come true. Word around town is that the same engine that powers the 580-hp 5.2L twin-turbo V10 in the recently announced Audi RS6 Avant could also find its way to the back hatch of the Audi R8. We first reported on the possibility of a twin-turbo V10 back in February, and it seems the stat sheet on the RS6 has merely stoked the flames.

During a recent Bimmer-hunting expedition at the Nurburgring, ace photog Hans Lehmann was able to procure a shot of the engine bay of a development mule for the 2010 BMW 7-series. When inspecting the layout, he noticed two intercoolers, and the best guess now is that the V8 fitted to the new 7-series could be the same engine employed in the new M3. With over 400 horsepower on tap in naturally-aspirated guise, it's not a stretch to think that this blown motor could produce upwards of 500 HP with

Although the BMW 7-series has undergone some mild styling tweaks over the past few years, it seems that more is on the way, all in an effort to tighten the reigns of the mangled Bangled versions that caused drivers to bleed from their eyes.

If such a thing is possible, Volvo 240s have an even mustier image in Australia than they do in the United States. That's good for those of us who know that they're anvil tough and respond well to modifications. Being front engine, rear wheel drive and European, the ingredients for a stormer are there, if you care to do some work. Additionally, 240s are super easy to work on, and there's a decent enthusiast base, especially now with the interweb tubes in full swing.

By many accounts, the new GT3 is the greatest 911 ever. Insane levels of grip, coupled with prodigious power delivery and styling that only a purist could love, it might seem unnecessary to mess with perfection. Porsche disagrees. Again.

It's nothing new that torque addicted, diesel junkies abroad get all the cool stuff, and now this. BMW just released details on its new 2.0-liter, variable twin turbo diesel engine that is making 204 HP and almost 300 ft.-lbs. of torque. The two-stage turbo system, initially introduced on the 535d, all but eliminates any amount of lag by utilizing a smaller turbo at low engine speeds and a larger snail higher up in the rev range. The result: 147 ft.-lbs. at 1200 RPM and 295 ft.-lbs. of twist at

May we first present to you a grain of salt, which you should take with what we're about to say. A comment left on an earlier post today confirming the G37 Coupe's new name led us to the Freshalloy forums where a member had recently posted some tantalizing information.

It's only a matter of time before BMW drops its new 300-hp, twin-turbo 3.0-liter six-cylinder engine into a 3-Series sedan body, and the crew who lives life in the left lane have secured spy shots of such a vehicle sporting a new, more aggressive nose. The new front fascia is more in-your-face than the façade found on the current four-door, and a pair of exhaust pipes at each corner out back are an instant indication this sedan isn't motivated by either version of the company's 3.0-liter

Over the past several months, a few Autoblog staffers have become obsessed with the performance potential of diesels. Sure the Audi R10's relentless asskicking of everything on the grid has certainly fueled our oilburning lusts, but what's available to us lowly consumers?

TechArt knows its way around a Porsche, so we aren't the least bit surprised to learn that they've coaxed 600 horsepower out of the Cayenne Turbo.
