Yesterday, which just happened to be Toyota’s 76th birthday, I attended the manufacturer’s Hybrid World Tour conference in Ypsilanti, Michigan.

For the event, Toyota gathered together, for the first time, its entire alternatively fuelled vehicle range from around the globe – from the little iQ EV to the fantastic TS030 Le Mans racer, which won't available any time soon at a dealer near you, unfortunately. Between Toyota and sister brand Lexus, there are 23 hybrid models on offer around the world.

The theme of the event was Toyota’s past, present and future as far as hybrid and other strands of alternative technology is concerned. To me, one of the unspoken messages was that while many other major manufacturers have either cautiously dipped their toes in the alternatively fuelled market or arrived at the hybrid party fashionably late, Toyota has been at this game for 16 years.

To misquote Kermit, it’s not easy being the first to go green. When the original Toyota Prius was unveiled to the world back in the late 1990s, it was embraced by early adopters but ignored by the majority. It was apparently dismissed by GM’s Bob Lutz as little more than a science project.

What that first Prius did do, though, was open up a demand for more fuel-efficient vehicles that didn’t even seem to exist previously. In 1997 a gallon of petrol was cheaper than a gallon of bottled water in the US, and motorists paid little mind to fuel economy and CO2 emissions.

However, it wasn’t too long before the issues of fuel prices and urban congestion started to become higher priorities for motorists, and awareness of Prius and other early hybrids began to grow.

Eco-minded Hollywood A-listers such as Cameron Diaz endorsed the Prius by rolling up to award ceremonies in one. The car also got a starring role in Larry David’s Curb Your Enthusiasm comedy show. 

Another turning point came in 2006, when a thinly disguised hybrid car named the ‘Pious’ was the focus of the subversive cartoon South Park. An episode entitled ‘Smug Alert!’ lampooned the perceived superiority complex of Prius drivers, portraying them as blinkered eco-evangelists. It wasn't the first time the 'Pious' gag had been used; it had earlier appeared in the computer driving game Grand Theft Auto, which featured a car that looked remarkably similar to the Prius Mk1. 

Some major corporations might take a dim view of being mocked by potty-mouthed animated children. Instead, Toyota viewed it as a positive; if its hybrid car was now prominent enough to be sent up on national television, it was clearly doing something right.

The Prius’s trajectory has continued. Now in its third generation, it makes up a significant portion of the five million hybrid Toyotas that have been sold around the world. It has grown into a ‘family’ within the Toyota brand, and customers in the US can choose from four variants; as well as the original car, the larger Prius+ and the Prius Plug-in that we get in Europe, there’s also the Yaris-based Prius C hatchback.

Some remain unconvinced by hybrid technology, but it has developed into a more widely accepted part of our automotive landscape.

Many experts believed that hybrid cars would be a relatively short-lived phenomenon; a ‘bridging technology’ between internal combustion engines and emerging full electric or fuel cell technologies.

Takeshi Uchiyamada, chairman of Toyota Motor Corporation and chief engineer on the original Prius, has a telling response to this: “If this is a bridging technology, all I can say is that it is a very long bridge.”
