Sirius and XM have buried the hatchet and merged their content, to the likely displeasure of many. XM closes 15 stations while simultaneously adding 22 new selections to the lineup, and Sirius pretty much broke even, trading 11 stations for 10 new ones. As has always been the case, the sports fans fare the best. Reception is reportedly better, too, though we're sure the lossy-codec lack of fidelity still makes it all virtually unlistenable to anyone that pays attention. If you don't care that cymbal crashes on SatRad sound like a pair of metal trash cans being hurled down a fire escape, you'll likely be pleased with the shuffling; though we hope they've left our beloved Soulsville alone.

Not too long ago, Hyundai didn't compete directly with anything coming out of Germany (or perhaps that's the other way around). Now Hyundai is determined not to let up on its recently-made foes. Today it unveiled the R-Engine, a new diesel in two capacities that the company says "can comfortably beat the power outputs of all German and French competitors." So there.

The Euro-V compliant, common-rail lumps come in 2.0-liter and 2.2-liter flavors, each with piezo-electric fuel injectors and electronic variable geometry turbos. Refinement comes via an internal, silent steel timing chain and a lower balance shaft housed in a stiffened ladder-frame housing. Weight has also been reduced thanks to a head cover, intake manifold and oil filter housing all made from plastic.

The 2.0-liter R-Engine puts out 181 hp and 289 lb-ft. That compares to 170 hp and 258 lb-ft for Audi's 2.0-liter TDI. The 2.2 liter Hyundai diesel pushes 197 hp and 321 lb-ft. , which compares with 215 hp and 398 lb.-ft. for Mecedes' 3.2-liter BLUETEC CDI.

Hyundai says the first vehicles to get the new diesel R engine will be SUVs and large sedans sold in Europe. Unfortunately, there appear to be no plans to bring it to the U.S. where our diesel emissions standards are higher than the Old Country's, at least for now.

If current rumors prove accurate, General Motors has big plans for its line of high-feature V6s, and with good reason. These six-cylinder engines make class competitive power and are very smooth. Thanks to direct injection, the engine range also offers excellent fuel efficiency when mated to GM's equally new six-speed automatic transmission. We recently heard that a new 3.0-liter version of this powertrain duo would make an appearance in the new 2010 Buick LaCrosse, and now we're hearing the engine will also be optional in the upcoming Chevy Equinox and standard in Cadillac's new SRX. Expect the new 3.0-liter V6 to offer around 250 horses and fuel efficiency slightly under 30 mpg on the highway. The Equinox's standard engine will be a new 2.3-liter direct-inject inline four-cylinder unit making something north of 200-horsepower, while the uplevel Caddy SRX should get the optional 300-plus horsepower 3.6L powerplant as found in the CTS.

One of the highlights of the recent Audi Mileage Marathon for participating journalists was the in-car internet connectivity. The Q7s and other vehicles used in the marathon were equipped with a Cradlepoint mobile WiFi router and USB wireless broadband adapter. We were able to open up our laptops (when we were in the passenger seat, of course!) and connect to the net to write our stories while on the go.

Delphi is now teaming up Autonet mobile to market in-car internet their connectivity products. Autonet is the company providing the in-car WiFi uConnect system that will become available from Chrysler dealers this fall. That unit is basically a standard WiFi router with a broadband adapter installed inside the box. The Delphi-Autonet partnership will take this technology and go a few steps further to add a variety of telematics services as well as improving the robustness of the systems. One of the issues that automotive engineers have to deal with on modern cars is radio frequency interference. Delphi will be using its experience in automotive electronics to help Autonet harden its systems and meet the requirements of carmakers for factory installation.

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.
