Today we've seen something quite small and extremely awesome: a small-scale V12 engine designed for model radio controlled vehicles. This is an entirely functional model and features twin camshafts and overhead valves. It's air-cooled to simplify things by ridding itself of the need for complex water jackets, radiators and the associated plumbing, though the crankshaft is made from multiple pieces. The lilliputian engine displaces just 87-cubic centimeters, but produces between 6 and 8 horsepower running on a mixture of methanol and nitro methane. The best thing of all is the builders say they will be making kits available soon so enterprising craftsmen can power their RC cars, planes and boats with a real V12. To truly get an idea of just how awe inspiring this little machine is, click past the break for a video of the mini V12 in action.

As is well known by now, Ford and Navistar have parted ways and the Blue Oval is developing diesel engines in-house to replace the PowerStroke lumps still being used. Slated to appear in Ford's trucks by 2011, the new oil burner code-named Scorpion is a 6.7-liter V8 with a host of innovations, some of them seemingly borrowed from cross-town rival GM.

But the first thing you'll notice is that mammoth radiator. PickupTrucks.com estimates that the cooler up front is up to 20-percent larger than the one on the 2008 Super Duty, and that one had already been enlarged by 33-percent over its forebear. The extra cooling could be needed for "extreme towing applications", and if there's one truck that's an extreme tower, it's the F-Series Super Duty.

The Scorpion diesel's innards will be enhanced with reversed intake and exhaust flow, something found on GM's Duramax diesel, and lighter aluminum cylinder heads. Nor will the Scorpion sacrifice mpg for its extra oomph: gains of 40 hp and 70 lb-ft will come with three more miles-per-gallon thanks in part to the truck's new 6-speed tranny that's debut as we speak on the new F-150.

Rumors of a new four cylinder engine from BMW have been confirmed by BMW's North American leader Jim O'Donnell. Questions on whether it will be offered in the United States, though, are still very much in the air. "We can't really confirm or deny when it is going to come into the US, or if it is going to come into the US, until after the election and the government makes it clear what is going to be the platform that manufacturers have got to work to," says O'Donnell. It really seems so simple to us. If an automaker has a new engine that offers both good performance and good fuel economy, it should be offered in the U.S. market.

Granted, the last effort to sell four-cylinder Bimmers in the States didn't go over so well. But BMW's reputation was earned first by cars like the 2002, which was motivated by a sprightly little four-banger. Considering the fact that BMW owns the MINI brand, the automaker should know better than anyone else that Americans are now willing to spend a good deal of money on small cars with small engines. We'll gladly support a revival of the tii badge on a lightweight 1 Series platform powered by a nice turbo four.

750-hp 7.5-liter V12 from the Cadillac Cien concept

Here's a shocker: Cadillac has reportedly canceled plans for a range-topping V12 engine. Really, you don't say? Last we checked, General Motors didn't seem to have any problems extracting plenty of performance from its 6.2-liter supercharged and 7.0-liter naturally aspirated V8 engines, and the majority of the development work has already been done for a Caddy installation. Additionally, we've heard some rumors of a possible twin-turbo version of GM's excellent 3.6-liter direct injection six, which could find a cozy spot under the hood of the next Cadillac sedan.

Cadillac is also said to be reconsidering its premium large sedan, where the V12 was originally intended to reside. In its stead, GM's classiest division will focus in on the replacement for the STS and DTS sedans. Also rumored is a new naming convention, as if the waters weren't already murky enough. Will the next Caddy sedan be known as the DT7? We sure hope not. Will it be based on the new Zeta platform? Well now... that decision would get our seal of approval.

Click above for a high-res gallery of the Lotus Exige 270E Tri-Fuel

Lotus Engineering has been hard at work developing new engine technologies that allow the use of sustainable alcohol fuels. It's recent Exige 270E Tri-Fuel concept showed that the British firm knows how to make an engine run on various fuels, including gasoline, ethanol and methanol. In fact, the 270E Tri-Fuel concept was the most powerful Exige ever conceived by the Hethel-based company and made its highest power output using synthetic methanol fuel. Lotus has started a new research project called the OMNIVORE engine -- cleverly indicating that it will run on anything -- that uses a single cylinder with direct injection and a variable compression ratio in order to maximize power and efficiency while running on various alcohol fuels. The higher octane rating of alcohol fuels will allow the engine to run with higher compression, thereby offering more power, while also toning itself down to run on lower-grade fuels as well. Read the press release after the break for more details.

Click above for more shots of the GM LSA V8 and its Eaton supercharger

The ongoing debate between the supercharger camp and the turbo boys isn't likely to die along with large, fuel-thirsty performance engines. In fact, Eaton believes that the market for both power-boosters will continue to grow at an extremely fast pace along with the rising price of gas. Because manufacturers are looking to downsize their engines, power-adders like the supercharger are becoming increasingly necessary in order to deliver the kind of performance new car buyers have come to expect along with the low fuel consumption that is becoming increasingly necessary.

Unlike the high RPM power generally associated with heavily-boost turbocharged engines, superchargers produce added power at all engine speeds. The downside is that engine power is used to drive the compressor, which reduces the available power gains somewhat. In order to make up some of that lost power, Eaton is developing variable-speed superchargers, which will allow for good power from idle through redline with a reduced strain on the engine. For our part, we fully support the use of both turbochargers and superchargers on any and all new cars. Solely in the name of fuel economy, of course.

Yes, we were among the suckers who endured the idiotic lines, activation woes and intermittent service that you've undoubtedly read about after the iPhone 3G's launch this past Friday. But our reason for suffering through myriad hassles to get our hands on Apple's newest hotness wasn't purely selfish. We wanted to see whether the iPhone 3G's new GPS functionality was worth the cost of admission or if we'd be better off buying one of the many stand-alone navigation units currently on the market. Make the jump to find out if it's worth your hard-earned cash and a place on your dash.

We've already gotten a sneak peak of what the 2009 BMW 7-series will look like on the outside ahead of its official launch, but the interior – and iDrive in particular – is still veiled in a cloak of secrecy. However, Bimmerfile has supposedly gotten the inside dope on the new multi-function brushed aluminum mole.

According to Bimmerfile, the new iDrive interface will take a cue from one of our favorite in-dash control units – Audi's MMI – with a new interface that has a similar list design and selection system. The screen resolution is higher, which makes the maps and text "more visually appealing" and the submenus are reportedly "more like bookmarks," which should facilitate an easier flow of information.

The new display will also allow show maps in full screen, rather than the split screen in the previous version of iDrive, and radio and CD functions are now available in two separate menus. When playing a CD, the current song will be displayed in a "frame" at the top of the screen, with the list of tracks shown below it.

The major revision, aside from a new phonebook contact list that allows for multiple numbers, is the date, time and radio station bar migrating from the iDrive screen into a central mounted display nestled between the two gauges on the dash. This is one feature that Audi's MMI has had for a few years and is a very welcome addition to the new iDrive. We'll hopefully have official information about the new system in a few days.

Okay, Mio's Knight Rider GPS unit is now officially "hella" cool. Engadget snagged some video of the startup sequence, and we're overcome by nostalgia for 1984. We're not excited to the point where we've gone digging for vintage Le Tigre polos or pulled that zombie leather jacket (the Thriller replica, natch) out of deep closet storage, but seeing that sweeping light bar and watching the flanking LEDs twinkle to the dulcet tones of William Daniels brings back sunny memories for those of us that lived it the first time around. Even cooler is that there's a bank of 300 names to choose from, so odds are good that KITT will greet you personally – that closes the sale right there, we officially want one.

Click above to view a video of Chrysler's uConnect in action.

At Chrysler's annual "What's New" gathering at its Chelsea Proving Ground, we were able to get a demonstration of the new uConnect Web system, which transforms any vehicle into a rolling WiFi hot spot. The hardware consists of a WiFi router with a built in wireless 3G modem. The 3G modem automatically connects to the internet and allows any WiFi enabled devices, such as a laptop, iPod Touch, Nintendo DS or XBox to connect, as long as you're within range of a cell signal. Chrysler is offering the system as a dealer installed option through it's Mopar parts division starting this August. Initially, it will only be available for 2009 models, but earlier models will be added further down the road. The system will cost about $500 installed plus $29 a month for unlimited service, and if you sign up for a two-year contract you get two months for free. Theoretically, you could use the system as your home internet service with your car parked in the garage, making the initial cost of installation and monthly service charges a bit more palatable. Check out a video of the demonstration we received after the jump.
