toyota s prius chief engineer reveals the future of the automobile part three a

Back on Friday, Toyota’s Chief Engineer Satoshi Ogiso and TTAC talked about the past of the Prius, and the future of the automobile. Back to the here and now: We also talked about a car that has been a ( badly kept) secret until today: A compact hybrid that suddenly makes former miser-meisters (such as the Honda Insight or the Mazda2) look like gas guzzlers. It is the Toyota Aqua, probably called Prius C when and if it lands on other shores.

With an unheard-of fuel efficiency of 35 km/L (82.3 mpg) as measured under the new Japanese JC08 test cycle, or 40 km/L (94 mpg) when measured in the 10-15 cycle, the car is 30 percent better than its segment competitors.

  • Honda’s new compact Insight hybrid delivers 27.2 km/L (64 mpg) as measured under the JC08 test cycle and 31 km/L (72.9 mpg) as when measured in the 10-15 cycle.
  • Mazda’s new Demio, better known as the Mazda2 stateside, wrings 25 km/L (JC08, 58.8 mpg) or 30km/L (10-15, 70.5 mpg) out of a conventional engine using Mazda’s Skyactiv technology.

These numbers are definitely non-EPA. Ogiso wouldn’t even hazard a guess for the EPA number.

Ogiso worked his team hard to get to these numbers:

“Usually, people look at the competition and want to be a few percent better. I set the Aqua target at 40 kilometers per liter. That is 30 percent better than the competition. Everybody said: How can you set that target so high? Why is that number needed? If the competition is at 30 kilometers, aren’t 35 good enough?”

Not for Ogiso and not for Toyota, which is finding its old fighting spirit after the many setbacks it had to endure. Not only is the car a super-saver at the pump, it also will be priced “affordably” when it will be launched in Japan in late December 2011. The exact price remains under wraps, and may not even be announced at the Tokyo Motor Show. The Nikkei [sub] had figured it will cost $4,000 less than the Prius.

Remember when Ogiso thought back to the bad old pre-Prius days?

“At the time, the battery, motor, controller, these components were all huge and heavy. I drew a compact car, 4 meters or so long, with enough interior for 4 passengers. The rest of the space was very tiny, and I had to stuff these huge components somewhere.“

With the Aqua, he had to repeat that feat again.

“Cost, size, and weight is greatly reduced from the original Prius.”

Prius hybrid technology had to be further miniaturized to fit into a car that is 157.3 inches long (Prius: 175.6) and has a slightly shorter 100 inch wheelbase (Prius: 106.3).

Ogiso thinks this car will send other makers back to their CAD stations:

“The Prius is the game changer in the midsize class. The Aqua will be the game changer in the compact class in Japan.”

Just in Japan? What about the rest of the world? Ogiso cites “currency and production issues” that might delay the arrival of a Prius C on other shores. A Prius C is tied to where Prius hybrids are made, and that’s Japan, Thailand and soon China. The expensive parts, the power trains come solely from Japan. The high yen doesn’t make Japanese exports low cost. That’s one thing Ogiso can’t engineer.

    Yet another car that will not be coming to our shores anytime soon . . .

    If that’s the real Prius C (Aqua? Really, JDM?), it’s the first time I’ve seen its final form – and, well, it’s NOT AS BAD as I expected. Sort of Yaris-y in the generic Toyota idiom. Doesn’t broadcast it’s hybrid-ness, tho. (Which is not a small part of the regular Prius appeal.) All minor sins absolved if fuel economy is awesome and price reasonable. Otherwise, it will join the Insight, CR-Z, and HS250 in hybrid purgatory.

      That's it. Final shipping version. Real pictures. This December at a Toyota dealer near ... me.

  • Dusterdude The "fire them all" is looking a little less unreasonable the longer the union sticks to the totally ridiculous demands ( or maybe the members should fire theit leadership ! )
  • Thehyundaigarage Yes, Canadian market vehicles have had immobilizers mandated by transport Canada since around 2001.In the US market, some key start Toyotas and Nissans still don’t have immobilizers. The US doesn’t mandate immobilizers or daytime running lights, but they mandate TPMS, yet canada mandates both, but couldn’t care less about TPMS. You’d think we’d have universal standards in North America.
  • Alan I think this vehicle is aimed more at the dedicated offroad traveller. It costs around the same a 300 Series, so its quite an investment. It would be a waste to own as a daily driver, unless you want to be seen in a 'wank' vehicle like many Wrangler and Can Hardly Davidson types.The diesel would be the choice for off roading as its quite torquey down low and would return far superior mileage than a petrol vehicle.I would think this is more reliable than the Land Rovers, BMW make good engines.
  • Lorenzo I'll go with Stellantis. Last into the folly, first to bail out. Their European business won't fly with the German market being squeezed on electricity. Anybody can see the loss of Russian natural gas and closing their nuclear plants means high cost electricity. They're now buying electrons from French nuclear plants, as are the British after shutting down their coal industry. As for the American market, the American grid isn't in great shape either, but the US has shale oil and natural gas. Stellantis has profits from ICE Ram trucks and Jeeps, and they won't give that up.
  • Inside Looking Out Chinese will take over EV market and Tesla will become the richest and largest car company in the world. Forget about Japanese.
