This P-51 Mustang replica flies with a Honda Odyssey engine

The legendary WWII P-51 Mustang fighter ranks right up there with hot dogs, baseball, and apple pie. So sought after is the original Mustang that one of the 200 or so airworthy P-51s left will run you at least $1.5 million. That's why there's a thriving replica market with three-quarter-scale aircraft like this Titan T-51D Mustang. It looks every bit the part until you crack open the cowling and find not a howling Rolls-Royce Merlin V12, but the V6 from the Honda Odyssey minivan. To be precise, the Titan T-51 uses Honda's J35A6 60-degree SOHC V6. It's one version of the ubiquitous J-series engine, found in the Odyssey minivan as well as the Honda Pilot. Other variations of the Ohio-built powerplant pull duty in the Accord and several Acura models. But why a Honda V6? Titan Aircraft president John Williams says the company began production of the T-51 with a Rotax 912F four-cylinder boxer engine, but its 100-horsepower output wasn't cutting it for customers. They wanted "more power and more noise." So the search began for a lightweight, easily-packaged V6, leading first to a Suzuki 2.5-liter with 160 hp. "Our guys still wanted more power, so the next choice was either going to be a Chevy V8 or a Honda V6. The Honda is a little bit lighter and from a V6 standpoint, it's a brute. In the Honda Pilot or the Odyssey, it's rated from 240 to 250 horsepower," Williams explains. Converting the V6 to an airworthy powerplant requires minor modifications, such as swapping the stock engine control unit (ECU) for an aftermarket one. Car-specific parameters for things like anti-knock sensing and rev limiters simply don't work well in the air. "You don't want your timing retarded when you're trying to clear a tree," Williams chuckles. With a hotter Acura camshaft and exhaust modifications, the naturally aspirated Honda engine makes about 300 hp in the T-51D, Williams says. The V6 mates to a custom gearbox designed to yield a 2-to-1 reduction for the propeller. Rather than the original Mustang's crankcase oil, the Titan's nosecase uses automotive gear oil. And while the engine can obviously use regular unleaded from any gas station, it runs well on the 100-octane low-lead aviation fuel commonly found at airports. The T-51 is a kit airplane that buyers can build themselves for less than $100,000. And like most kit manufacturers, Titan offers a builder-assistance program to help with assembly.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

Inside Honda's ghost town for testing autonomous cars

On the edge of the San Francisco suburb of Concord, California sits a ghost town. Dilapidated buildings and cracked roads are framed by overgrowth and slightly askew street signs. The decommissioned five acre portion of the Concord Naval Weapons Station that once housed military personnel and their families is now home to squirrels, jack rabbits, wild turkeys and Honda's mysterious testing lab for autonomous vehicles. This former town within a Naval base – now dubbed "GoMentum Station" – is the perfect testing ground for Honda's self-driving cars. An almost turn-key solution to the problem of finding somewhere to experiment with autonomous vehicle inside an urban area. Thanks to the GoMentum Station, the automaker has access to 20 miles of various road types, intersections and infrastructure exactly like those found in the real world. Just, you know, without all the people getting in the way. While the faded lane markers and cracked asphalt might initially make it difficult for the car to figure out what's going on around it, that's exactly what you want when training a self-driving system. Many roads in the real world are also in dire need of upkeep. Just because autonomous vehicles are hitting the streets doesn't mean the funding needed to fix all the potholes and faded lane markers will magically appear. The real world doesn't work that way and the robot cars that will eventually make our commutes less of a headache will need to be aware of that. Plus, it's tougher to train a car to drive downtown than to barrel down the highway at 80 miles per hour. A company is going to want to get as much practice as possible. While semi-autonomous driving on the everyone-going-the-same-way-at-a-constant-speed freeway is already a reality, navigating in an urban environment is far more complex. If you've driven on the streets of Los Angeles, San Francisco, New York, Chicago or Seattle you know that driving downtown takes far more concentration than cruising down the interstate. With all that in mind, Honda's tricked out Acura RLX did a good job during an (admittedly very controlled) hands-free demo. It didn't hit either of the pedestrians walking across its path. It stopped at stop signs and even maneuvered around a mannequin situated in the middle of the road. The reality is, watching a car drive around the block and safely avoid stuff is boring. Not to metion, Google has been doing this for a while in the real world.
