Japan's government gives hydrogen vehicles a big boost

The Japanese government is really paving the way for hydrogen fuel cell technology on its roads. Japan's Ministry of Economy, Trade, and Industry is changing regulations on fuel tanks to make hydrogen cars more appealing to drivers, which should help put the country ahead of others in the race to develop a viable H2 fleet. Japan is raising the allowed pressure of hydrogen tanks from 700 atmospheres to 875, which has the effect of increasing driving range by 20 percent. This move puts the country in line with others with high-pressure fueling regulations. Japan is also in talks with the United Nations and the European Union to streamline inspection rules to make it easier to export Japan's fuel-cell vehicles. Toyota premiered its hydrogen-powered FCV Concept at the Tokyo Motor Show last year and plans to release a production version as early as next year. Honda also plans to build its own fuel-cell cars for 2015, and it debuted its FCEV Concept at last year's Los Angeles Auto Show. Nissan is sending mixed messages on hydrogen, both questioning the availability of a refueling infrastructure and working on developing the vehicles. In Japan, a relatively small country, increasing the range of fuel-cell vehicles makes creating a usable infrastructure a bit less daunting. Will hydrogen-fueled electric cars see the same sort of success as Toyota's Prius hybrid or battery-powered EVs? Only time will tell, but we can keep our fingers crossed that it will, and that the popularity spills over beyond Asia.

Honda, Top Gear working on 130-mph lawn mower

We're not even sure they've got a blade of Kentucky Bluegrass to cut, but the folks at Top Gear have gone ahead and started building what will become, if they're successful, the world's fastest lawn mower. Actually, it appears Top Gear is not doing much of the design and assembly work at all, instead having solicited help from experts at Honda and Team Dynamics, which oversees the automaker's touring car efforts.
What the three are working on is a riding lawnmower with a 110-hp engine that can reach 60 miles per hour in four seconds and trim turf at speeds up to 130 mph. If they succeed, such a maximum velocity would put them well ahead of the current record for the world's fastest lawnmower, which is 96.529 mph set by Bobby Cleveland and his Snapper race mower at the Bonneville Salt Flats in September of 2010. Top Gear hasn't said whether or not it will officially go after Cleveland's record, but the build will be featured in an upcoming issue of the Top Gear magazine and is scheduled to be completed by June 17, so we may learn what this maniacal mower's true purpose is then.
According to TG's report on how the build is going, as well as the video of it being fired up (literally) for the first time below, there aren't many actual mower parts left on this machine. What started out as a Honda HF2620 mower now sports wheels and tires from a racing quad, a back axle from a go-kart, a steering rack from a Morris Minor and a 1000cc engine from a Honda VTR1000F sport bike. All that remains from the original mower are the pedals and body panels; even the steel cutting deck has been replaced with a lighter fiberglass version. And blades? This mower will be bladeless, instead using two electric motors to spin lengths of brake cable like a weed whacker.

McLaren working on P15 supercar to slot between 650S and P1

McLaren has been busy these past few years. It launched the MP4-12C in 2011, the 12C Spider in 2012, the P1 in 2013 and (most recently) the 650S in 2014. But it's not about to stop there. It's got an "entry-level" model in the works, set to take on the Porsche 911, and - according to information reported by Car and Driver and confirmed by McLaren in correspondence with Autoblog - a new flagship model, too.
The project is internally codenamed P15, and it calls for a new flagship that will cap the company's lineup once the P1 finishes its limited production run, but carry a price tag in the neighborhood of $500k to slot in between the P1 and the new 650S.
Just how, you wonder, can McLaren possibly develop another supercar each year? Simple: underneath, they're all essentially the same. (Only we're sure it's anything but simple.) That is to say they're all based on the same carbon monocoque structure and powered by the same 3.8-liter twin-turbo V8 mated to a seven-speed dual-clutch transmission driving the rear wheels. What differentiates them is what the engineers in Woking build around that monocoque and how they tune the engine: +/- 600 horsepower in the 12C (depending on the year it was built), 640 hp in the 650S, or 727 hp in the P1 (with another 177 from the electric assist). The 911 fighter would likely develop in the 500hp range, and the P15 will probably land in the upper 600 (or lower 700) range.
