This most likely has no future for short and medium range light passenger vehicles. Vastly improved battery technology soon to be available will cement EV's technology lead even more. However this may be an ideal environmental solution to long range large truck and train transportation.
Why don't they cut the length of the internals, shaft etc. and use multiple sections stacked, and offset by some angle to smooth out the torque ripple. Just like more cylinders in an ICE is used primarily to smooth out torque. This is even more critical to have smooth torque in electric motors to take advantage of the zero RPM capability.
SCE has a ripoff EV plan that does not really save any money because day rates are so much higher. Is PG&E any better? The real reason this is happening is providing power to charging EV's is so profitable. Selling kWh for roughly 5 to 10 times production cost, and the more you sell the lower the delivery cost. $0.20/kWh is equivalent to $7/gallon of gasoline. EV's are so efficient that it's accepted. But this is really not encouraging EV's and zero emissions unless you go solar, not possible for everyone. The ICE fuel business has so much smaller profit margins due to competition.
DavidJ, it's a pure mechanical flywheel KERS. Another advantage of this design is it allows maximum kinetic energy recover during braking. The front brakes could be downsized a lot. In contrast, F1's current rules greatly limit braking energy recover by the KERS.
I would like to see how it works. Stiff springs and traction control will make it easy to manage weight transfer. I see the advantage here. Aerodynamic center of the more efficient under body ground effect wants to be forward. Chassis have become super lightweight while the rest has become heavier. So a rear wheel drive design suffers from excessive rear CG unless a draggy rear wing is added. So this could be more efficient aerodynamically. The other big issue is will this have good stability, i.e. no possibility of flipping... Why not use rear electric motors?
The technology from this will trickle down, especially to high performance cars. Funny how they always show the picture with the fake exhaust layout.
This would be good to make carbon free H2 to replace home natural gas.
Totally agree with Smil. Obese ICE cars should be taxed extra to provide incentive to light weighting. Ford did a good step with the Aluminum trucks. EV's and HEV should be less taxed proportional to MPG. There should also be mandatory higher insurance coverage for other persons injuries in accidents. Airlines should also charge extra for obese. Why should a little kids airfare subsidize...
I like the idea of self driving cars, except if they drive too slow due to programmed lack of confidence.
The reduced mass of 12V Lithium Ion could save more than lead. If 12V Lithium Ion became mass market the cost would be reasonable since less overcapacity is needed. The question is how much over sizing is needed for 12V Lithium Ion in cold weather.
Wiring up home EV charging is so much easier and cheaper. EV's are also so much simpler. The revolutionary battery tech will make EV's the way to go before HV's. The Mirai looks equally expensive and complicated to a ICE car. Long term, H range extender's might be worthwhile.
Is this related to the submetering pilot program in California.
Perfect direct drive EV range extender, allowing 4wd. Connect it to the wheels with a simple clutch single speed gearbox with ratio optimized for highway driving. The turbo is not needed, but might be better for emissions and extra power.
Top reasons for this: Always hitting red lights - Need more micro hybrids, or full hybrids to recover energy. How many years before everyone can use the EnLighten App to avoid burning fuel and brakes? https://play.google.com/store/apps/details?id=com.otsys.notifier&hl=en Winter warm up losses. Lots of new ways to improve are coming to market. More weight in car in real world versus testing? Low tire pressure? Make TPMS mandatory. Front end alignment degradation. Engine degradation.
"five stronger than steel wheels they replace" is most likely engineering dumbed down to marketing. What was lost in translation is the critical failure mode, buckling, is easily increased by 5 times because the alloy is 3 times lighter and so generally needs to be 3 times thicker. Steel wheels are likely buckling critical, whereas alloy wheels are likely fatigue or fracture critical.
You forgot to mention reducing driver stress, fatigue and other negatives of driving in congested traffic...
So what about the other 20% loss EM energy? How do you prove it is safe to be nearby? Until now most EM is much lower power comm.
The video and narration is good. Take a look at it. The added cost could be offset by downsizing to fewer cylinders and better MPG from efficiency and a lighter engine and vehicle.
Actually it looks more compact than conventional overhead cams.
"pick their own gears" is a great idea! So the buyer can choose an economy/quiet 6th gear and just downshift when needed. The torque looks good enough that it may do well with a big overdrive. What is the MPG? This car looks very practical, fast, and probably very good MPG.
Low profile tires end up having much more rotating inertia (bad), wasting fuel in stop and go driving. Maybe they also have more drag with a more squared shoulder. Look at top level race cars, none have very low profile tires.
The aero wheels might look better with different paint options, like all black, or all metallic.
I wonder if the break-in period, which can be long, still reduces the MPG.
Will this lower mercury content as well?
What about mercury from bunker fuel?
