Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

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.

Sampling toys and tools in the Honda Dream Garage

I have two Hondas in my modest garage. One is a 1972 CB450 that I cherish but rarely ride, the other a 2014 HRR216 mower that my neighbors probably wish I'd use more often. Not quite dream garage material, but I like my trusty Hondas all the same. So I was pretty geeked to visit what Honda calls its Dream Garage. Spoiler alert: There was no actual garage. The various Honda products were spread out over a few acres of private land. And before you ask, no, the HondaJet wasn't in attendance. No confining garage meant I got to try a bunch of this stuff out. Honda makes such a wide variety of products, and so many of them, that it is the number one maker of engines in the world, having built 28 million in 2014. Highlights included a smattering of motorcycles, some rugged side-by-sides, the Uni-Cub assistive mobility device/powered stool, a few boats, Honda's latest cars, and snowblowers. Yep, in Southern California in July. They used damp sawdust for demonstrations, which meant I got to run a giant snowblower in a t-shirt. Watch the video above to see me ride, drive, walk behind, and be assisted by some of Honda's latest gear that isn't a car. Some of my favorites: The Grom. I've wanted to ride one since it came out a couple years back. This miniature motorcycle is hilarious and surprisingly rideable given its 125-cc single, which puts out about eight horsepower. It'll do 45 mph pretty easily, which feels fast on this baby bike. The only thing that takes getting used to is the time required to glance down at the instruments – they're way down there. Otherwise, it's a normal motorcycle with tiny wheels and a tinier engine. Riding the Uni-Cub was another dream experience of mine. It's much more intuitive than a Segway and makes you look slightly less goofy. I felt like I was in an OK Go video. It was neat. One item that didn't make the video is the NM4 you see here: crazy anime-inspired styling, a dual-clutch transmission, and then more crazy styling. The DCT means your left hand and foot get a rest. I still grabbed for the clutch every time I started the bike, though. Old habits and their hard deaths. Honda is also putting a dual-clutch transmission into one of its newest side-by-side offerings, but it was only on display and not available to pilot. I drove one with a traditional auto and another with an automated manual – and paddle shifters!
