Why Toyota's fuel cell play is one big green gamble

Imagine going to the ballet on Saturday evening for an 8 pm performance. The orchestra begins warming up shortly before the show, but it turns out the star performer isn't ready at the appointed time. The orchestra keeps playing, doing its best to keep the audience engaged and, most importantly, in the building. It keeps this up until the star finally shows and is ready to dance ... which turns out to be ten years later. That's a Samuel Beckett play. It's also how many observers, analysts, alt-fuel fans and alt-fuel intenders feel about the arrival of hydrogen fuel cell vehicles (FCVs) – the few of them who are still in the building, that is. Toyota's hydrogen development timeline rivals that of the US space program. In fact, within the halls of Toyota alone, research on FCVs has been going on for nearly 22 years, meaning that one company's development timeline for FCVs rivals that of the US space program – it was 1945 when Werner von Braun's team began re-assembling Germany's World War II V2 rockets and figuring out how to launch them into space and it wasn't until 1969 when a man set landing gear down on that sunlit lunar quarry. The development of the atom bomb only took half as long, and that's if we go all the way back to when Leo Szilard patented the mere idea of it, in 1934. Carmakers didn't give up on hydrogen in spite of the public having given up on carmakers ever making something of it, so there was a good chance that hydrogen criers announcing the mass-market adoption of periodic chart element number two one would eventually be right. Now is that time. And Toyota, not alone in researching FCVs but arguably having done the most to keep FCVs in the news, isn't even going to be first to market. That honor will go to Hyundai, surprising just about everyone at the LA Auto Show with news of a hydrogen fuel cell Tucson going on sale in the spring. The other bit of thunder stolen: while Toyota's talking about trying to get the price of its offering down to something between $50,000 and $100,000, Hyundai is pitching its date with the future at a lease price of $499 per month ($250 more than the lease price of a conventional Tucson), free hydrogen and maintenance, and availability at Enterprise Rent-A-Car if you just want to try it out. We've seen and driven Toyota's offering and we all know its success doesn't depend on cross-shopping, showroom dealing and lease sweeteners.

Acura reveals performance EV concept called Performance EV Concept

After teasing a new EV concept for Monterey, Acura made good on its promise Thursday with the unveiling of its rather plainly named Performance EV Concept. Good news: Acura's first in-house EV will be a performance car. Bad news: It's not the one we all hoped it would be. Instead, we're getting another model in the grand tradition of the ZDX — pronounced front end and all. It seems that look is here to stay, so get used to it, because Acura says it plans to build a production model based on this concept starting in late 2025.  That's noteworthy not just because this is Acura's first in-house EV, but because it'll be the first production car to ride on any variant of Honda's new BEV architecture. The mainstream brand is planning to put something based on its 0 Series "Saloon" concept into production in 2026. That's quite the coup (no "e") for Acura, which spent most of the past two years talking about the Ultium-based ZDX project, which by all accounts will be the first and last Acura-badged product of Honda's tie-up with General Motors and its Ultium EV platform.  As you can probably surmise, Acura remains tight-lipped about specifics. Honda (and by extension, Acura) "concept" vehicles have a funny habit of being put into production almost exactly as they sit, so what you see here is likely pretty close to the mystery CUV's final physical form, but battery and motor specs remain nebulous for the time being. We expect a multi-motor setup engineered to mimic the behavior of the SH-AWD system Acura offers in its ICE vehicles. The concept's massive 23-inch wheels encircle a set of four-piston calipers and crossed-drilled rotors — the two most significant hints that we're looking at something meant to move quickly.  If you're in Northern California for Car Week, you can check out Acura's concept at The Quail. The company's presentation is scheduled for 10:36 a.m. local time (What is this, a train schedule?) on Friday. 

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.
