It's not electric so it's not advanced.

Ho hum, even more complexity and more to go wrong, more expense when it comes time to repair it. Look at that motor/transmission system, and compare it to an electric drive, the ICE is a joke. Hell, if you took an electric drive and a ICE drive and showed them to an engineer from another planet, who had never used cars, and said "which one makes more sense", the answer, of course, would be the electric drive.
The whole ICE industry is resisting the move to EVs for one reason only - the money they make from spare parts is most likely greater than what they make from initial vehicle sales, over the life of each vehicle.
But, the world is transitioning to electric transport, anyone not onboard with that will go the way of the Dodo, and good riddence.

Things like the motor driven water pump might not be the best idea. independent parts that drive critical functions will be a problem when the cars warrantee runs out. so it's good for maybe 10 yrs then 20 things start to fail and maintenance is more trouble than buying a new one, which is the whole idea and I don't like it.

It's incredible how much more efficiency engineers wring out of the ICE and accompanied gearboxes. But it's just no competition for the simplicity and reliability of an electric motor (without a gearbox). Electric cars are still expensive, but within 3 years cost, range and charging ability won't be a problem for mainstream affordable electric cars anymore. The ICE has served us well, but it's dawn is fast approaching.

A re-hash of a Toyota press release. C'mon guys, how about some explanation of the so called advances or improvements ? What does this mean ? "The stroke-bore ratio of the engine is 1.2, balancing power outputs. The engine has a wider valve (41 degrees) which allows for better intake/exhaust. New valve seat materials and laser valve seat cladding mean lower friction losses as well." How does the 1.2 ratio effect power output ? A wider valve ? You mean wider valve angle. And how does new valve seat material produce lower friction and what the hell is laser valve seat cladding ???

I'm thrilled to see the 8-speed tranny. If this engine and tranny in hybrid mode were available for my '07 Tundra, it would have been a great combo and I would have snatched it up. Yes, with that tranny, it would have more power than I'd need for anything except towing large trailers. I wonder if they'll do a trade-in on my 4.7L V-8...

Well done Toyota...for 3 persons who'll give a shit while the rest of us is investing in electric motors.

The world has to work with what works now. Not what will work in the future. That is why ICE will continue to advance. Electric cars have a major cost problem. Even at 35k, that is very expensive. Then there is the fact you can't use electric in any application where weight is a serious issue.
What caught my attention was this engine. They have a working engine at 40% efficiency. I calculated that off of the 186 g/kwh on diseal fuel. It can potentially get a lot more efficient. It delivers 40 hp while weighing 30 lbs. Very few moving parts. They are saying one of their engines with one type of fuel can get 2hp/lb.

Here's something to THINK about for all of the people writing nasty comments about this engine technology and only thinking all electric. First off, all electric vehicle represent and VERY, VERY small percentage of the market and other than the Tesla's, the rest of what's shipping gets horrible range. these electric manufacturers like Tesla, have to keep pace with building charging stations, otherwise, you have to wait in line at a charging station if it's near a major area since there are more electric cars and not enough charging stations. In addition, most all electric vehicles are vastly more expensive than traditional combustion and Hybrid cars. So for the time being, traditional combustion and hybrids are going to be the majority of the market and it's going to take AT LEAST 10 more years until All Electric makes a significant dent in total car sales. Electric vehicles have several major hurdles. 1. Battery cost. 2. Battery Range. 3 Charging stations

Our 2013 Prius Plugin has averaged 68 mpg, ignoring the 2.4 cent per mile electric fuel costs. @ $25k, we paid only a few hundred dollar premium over the standard Prius. The next Plugin will have 2x the electric range. We would achieve about 85 mpg with it, I think. Even without the Fed subsidy, it should also be available for around $25k. Once one gets to such a range for gas efficiency and considering its 700 mi range, such a car is quite a deal. I think it will be at least a decade before an all electric can compete with its practicality and economy.
