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.

2015 Pikes Peak Hill Climb: Practice Day 1

Based on what we learned from the first day of practice for the 2015 Pikes Peak International Hill Climb, the quickest race pace up the paved road to more than 14,000 feet above sea level may not be from internal combustion locomotion anymore. "If it all goes well, and the planets align, [under nine minutes] shouldn't be out of the question," said Paul Wilding, team manager for Nobuhiro "Monster" Tajima's Rimac Automobili Monster Sport E-Runner entry. Wilding added that if Tajima's car held up during the week it could finish first overall, which would be the first time an EV takes the overall crown at the hill climb. Last year, the gap between overall winner Romain Dumas' Norma M20 RD Limited and the fastest EV was just over two seconds. In the 2014 race, Tajima finished third in his class. "We think this car is the fastest way up now," said Wilding. "There's no affect from the altitude – this car is a monster, our driver is a monster." The practice, which isn't mandatory but is sanctioned by race officials, concluded Tuesday morning with a few surprises ahead of Sunday's race. Tajima will be racing for the fourth consecutive year in the all-electric modified division. Wilding said today's conditions weren't ideal and the race Sunday could be more challenging than initially expected. "It was a lot bumpier than we expected today," he said. "But today means nothing. It was all [reconnaissance]. Tomorrow means everything." The Honda ARX-04B LMP2 prototype brought to Pikes Peak had a difficult start to the week. Honda Racing spokesman Eric Mauck said the car struggled and didn't run in practice Tuesday. "We're looking for data and research more than anything else," Mauck said. "We're not going for Sebestain's record this year, we're just looking to gather information for years to come." Colorado-native, Honda driver, and Formula E racer Justin Wilson will pilot the LMP2 up the mountain Wednesday – assuming the car is ready. "He's obviously a guy that Honda thinks very highly of. Anytime we have an opportunity to put Justin behind the wheel of anything we want to," Mauck said. Honda driver Tetsuya Yamano, who is driving an all-electric Honda CR-Z in the exhibition class, echoed Mauck's assessment. "We're not making a racecar," Yamano said through an interpreter. "This is part of [research and development] and we're looking to get as much data back to engineers in Japan as possible ...

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.
