I'm surprised that they haven't come up with a gas/electric like a train... where the "engine" runs a generator that powers the drive motors. Tie a battery system into it, and you can have an electric vehicle around town, and a long distance drivable vehicle together! I shall respect you until you open your mouth, from that point on, you must earn it yourself. | |||

We just bought our third hybrid. In order, they were Ford Escape, Ford CMAX, and Toyota Venza. They gave 30, 40, and rated for 39 mpg I traded the CMAX as I had joint issues getting in and out of it. Then it was too low to fight rush hour. Think Prius size. We’ve had a couple of minor recalls but nothing related to the battery. One thing the electric crew doesn’t mention is the power grid. When an electrician was doing some work we got to talking. Home charging can be done fast or slow. Fast puts a strain on the grid. A street full of charging vehicles can cause an overload. “ The average electric vehicle requires 30 kilowatt-hours to travel 100 miles — the same amount of electricity an average American home uses each day to run appliances, computers, lights and heating and air conditioning.“ https://www.pewtrusts.org/rese...ge-state-power-grids As most owners come home and plug in the charging occurs in the early evening when demand is the highest. One idea is to charge by time of day or delay charging to start after demand drops. “ The work of destruction is quick, easy and exhilarating; the work of creation is slow, laborious and dull. | |||

I take it you didn't buy a Porsche 918 when they were available. I mean, affordable is all relative. | |||

The Chevy Volt works kinda like that. 40 miles all electric and will run using gas ICE as long as you keep gas in the tank just like most cars. | |||

The BMW i3 also had an option for an ICE range extender. Has a little ICE generator that would run and recharge the battery as you drove. Not powerful enough to keep up with the discharge rate while driving, but the constant trickle of power would add miles to the overall range. | |||

Toyota Corolla Hybrid here, getting real world @63-64MPG (epa 53-54). 11.4 gal tank, can do over 600 miles before fill. Have 20 gallons of stored non-ethonol in cans. If the SHTF, my range is just under 2000 miles if there are no gas stations working. Comes with all kinds of nifty things. Love it. | |||

What he wants sounds a lot like a McLaren P1. Technically, it's a hybrid.

I agree. Don’t we all and of course for the cost of a Chevy. | |||

My mother-in-law has a hybrid Camry, circa 2010. It still has the original battery and gets excellent gas mileage. I put in my order for a Ford Maverick Hybrid a couple of weeks ago. It should be much cheaper to buy and drive than the ridiculous current Ranger. ---------------------------------------------------- Dances with Crabgrass | |||

I’ve got the 2020 Toyota Highlander Hybrid, I’m going on 11 months now and my average is 42.3 mpg. My decision wasn’t a save the planet one just wanted good gas mileage. I fill up every other week instead of weekly. I like that. | |||

I don't know how other cars handle it, but Tesla allow a number of "smart" charging options. You can set the car to charge during the deep of night when demand is lowest (and in some places, when the power is cheapest). You can set the car to finish charging at a certain point by a certain time, so that the car spends as little time as possible at the limits of battery capacity (to preserve battery life). For example, you can tell the car to finish charging to 70% by 8am the next morning, and the car will calculate the amperage draw to required to get the car to that point as gently as possible. You can override that and tell the car to give you a full 100% on certain days you expect to use the additional range. If your typical daily drive only used 30% of the battery capacity, it's best to use the center 30%, perhaps from 70% to 40%. You don't want to deep discharge if possible and you don't want to fully charge if possible either. | |||

I see no reason to cut back on oil consumption, me using oil keeps plenty of people employed and I have no problem with that. "If" the majority of people went to electric, it would overload the current power utilities. A car or two per block is finest it could not handle every person with one. We should reduce regulations and let diesel cars that get 50 mpg be the norm. VW, Honda and others have proven it is easy to do if emission restrictions would be eased. That is a good solution. I have no desire for even a hybrid, I am fine with gasoline/diesel engines and will be for the rest of my life. Electric vehicles in my area is a dumb idea anyway, most trips are way too long for an all electric, with hurricanes and Texas ERCOT issues who knows when we will lose power and not be able to charge. I like oil, I like the way it smells, the way it feels and the way it powers my internal combustion engine. Batteries do not give me the same feeling. To me, batteries are the cats of propulsion means and the internal combustion engine is the canine. Give me a dog and a gas burning (or even diesel) engine and I'm good. Leave the electric vehicles to bumper cars in amusement parks. | |||

Hybrids are the worst of both worlds when you look at total lifetime energy use - from raw materials to finished product, to use, to disposal. Yeah you get better mileage and it might pay for itself in saved gas in a few years, but fast forward to battery replacement and eventual disposal and the numbers are unfavorable. Diesel electric locomotives and heavy equipment exist because the clutches, transmissions, and differentials needed to get that kind of motive force from the engine to the wheels would be too big and heavy to be feasible. Once you get big enough, it is the most efficient solution, especially for rail so you can keep the engine at peak power and ramp up the speed gradually by diverting power between the grid resistors on the roof and the traction motors. The old 2-stroke V-16's had a relatively narrow power band and lugging them up and down with the speed of the wheels through a "many speed" transmission is a non-starter. This MAY be an option for Class 8 OTR Tractors - with a diesel less than half the size of a typical 15L as backup power to charge the batters, but I am waiting to see if it really happens. Small gasoline DI Turbos are the best option now. My Civic Si 6-speed manual makes over 205 hp from a 1.5L DI 4-cyl with 20 psi of turbo boost, along with 190+ ft-lbs of torque at around 2400 RPM. And it gets over 40+ MPG on the highway and around 30 in town. The slightly lower powered Civics with the same motor get better mileage. It only cost me around $23K after discounts so why bother with a hybrid drivetrain? | |||

If Tesla's rig has the specs they say it does, it will make sense to do a true hybrid drive train, once other suppliers figure out how to get motors that powerful, and light. Should still have lower maintenance costs, and much better fuel mileage/be far more drivable. | |||

Arglifter, the ICE engine has been under development for such a long time that some formats have been deemed by engineers to have reached their pinnacle of design. Ducati, who is a motorcycle manufacturer has abandoned V twins because in their own words it has reached the end of its design cycle. They cannot extract any more mpg’s or HP from it and they compete in a racing series that actually places an importance on fuel economy and limits them to a finite amount of fuel consumption and places zero benefit to re-fueling and has no pit stops during the race series they compete in. Their ability to extract maximum power (better that everyone else including Honda factory racing who played an integral part of killing off a more powerful but more polluting ICE must be considered (two strokes) with regard to power output whilst simultaneously using the least amount of fuel is mind blowing to see. With modern tech maybe two stokes make a comeback, their power to weight ratio cannot be surpassed. It’s the fuel economy and spewing delicious blue smoke that led to their demise. Problems that modern tech can probably fix. I’m not buying the whole Tesla will adopt gas generator engines when they get better at power generation and fuel maps economy argument. There are plenty of engines that have already reachedb their pinnacle. ~~~~~~~~~~~~~~~~~~~ The price of liberty and even of common humanity is eternal vigilance | |||

People have been saying that about the ICE engine for at least 30 years that I know of. Current ICE engines are only 20-25% thermally efficient so there is a ton of room for improvement. We won't see much more because all the development dollars is going to EV but it's there. | |||

The true beauty of engineering is the mindset of rejecting accepted truths as truth and pushing forward. I’d say that some ICE engines have reached their pinnacle without allowing accommodations but I do believe others are not even close. ~~~~~~~~~~~~~~~~~~~ The price of liberty and even of common humanity is eternal vigilance | |||

For Tesla to ignore battery degradation issues whilst saying ICE engines need to develop more is retarded. To push development in only one area opens yourself up to vulnerably to another company who is clever and develops both ICE and EV hybrids simultaneously. Toyota is one company that comes to mind. The first company to make a hybrid doesn’t place much stock in EV’s. This is interesting eh? What do they have up their sleeve? ~~~~~~~~~~~~~~~~~~~ The price of liberty and even of common humanity is eternal vigilance | |||
