Honda CR-Z carbon-fiber prototype

When Honda rolled out the CR-Z a few years ago, it hoped to bridge the gap between those who would save the planet and those who would rather burn all of its resources in a glorious cloud of tire smoke. But enthusiasts recalling the CRX of 1980s vintage balked, imploring Honda to ditch the heavy battery packs and electric motors in favor of a lighter-weight, more conventional powertrain. At this point it seems less likely that Honda would do so at one end of the market than Porsche would ditch the hybrid component of its 918 Spyder at the other. But that doesn't mean Honda isn't still cooking up ways to curb the CR-Z's weight. And it had just one such idea waiting for us when we visited its Japanese R&D center at Tochigi last week.
Nestled in between the JDM hatchbacks, powertrain test mules and new technology prototypes Honda rolled out for us sat the experimental CR-Z you see here. While it may look mostly like the hybrid sport-hatch you can pick up at your local dealer (albeit blacked out), nearly all of this prototype's bodywork has been completely replaced, as have its basic underpinnings, with carbon-fiber reinforced plastic. The exotic material is usually reserved for high-end exotics, but like BMW is democratizing its use in the new i3, so too is Honda researching ways to implement the use of carbon fiber on a mass scale. This one-of-a-kind CR-Z prototype stands, for the time being, as the embodiment of that effort.
Driving Notes

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.

Pedestrian deaths increase; cell-phone distractions may be culprit

In Philadelphia, city officials are running a public-safety campaign that implores road users to simply "Put. Phone. Down." In Florida, a similar advertisement reminds people, "Alert Today, Alive Tomorrow." What's unusual about these messages is that they target pedestrians. Amid widespread concern about distracted drivers on American roads, there's a growing body of research that suggests distracted walking is equally problematic. Pedestrians engrossed in their phone, text or Tinder conversations are stepping into intersections without so much as a glance at oncoming traffic. That may be one reason pedestrian deaths are increasing. They jumped 15 percent in a five-year period between 2009 and 2013, according to a study released this week by the Governors Highway Safety Association, with 4,735 killed in 2013. In the same time, overall traffic fatalities have fallen by 3.4 percent. Pedestrian deaths now comprise 14 percent of all traffic fatalities, and approximately one pedestrian death occurs every two hours in the United States. Alcohol is still a top culprit – it's involved in 49 percent of pedestrian deaths on either the part of driver or walker – but as cities rush to implement a wave of slower speed limits, wider sidewalks and street medians to counter pedestrian deaths, there's new focus on holding pedestrians accountable for eliminating distractions. "Undoubtedly, motorists are responsible for many pedestrian accidents," said a July newsletter from the National Motorists Association. "But pedestrians must also assume responsibility for their own safety." This week's report from the GHSA cites growing research that suggests pedestrians aren't yet doing their part. At 20 high-risk intersections, 26 percent of pedestrians wore headphones, 15 percent were texting and 13 percent talked on the phone, according to a 2013 University of Georgia study. More recently, a William Paterson University study issued earlier this year found more than 25 percent of New York City pedestrians were distracted by either their phones or headphones. Half of the pedestrians who crossed with a "Don't Walk" signal were distracted. "Getting smashed at the bar? Don't get smashed walking home." - Minnesota public-safety campaign.
