I always buy my cars for the highest city mpg. This was back when I was living and working near Dallas. My first toyota was the '94 Corolla, with automatic. The epa shows it at 27 city/ 34 highway with it's little 105 hp engine. I never owned such a quality car after driving many GM cars for years. The GM's would have enough problems that I would trade for a new one after 85,000 miles. This '94 Corolla went 185,000 with the brakes replaced once, a new starter at 105K including a new timing belt.
Not only that, this same car got 36 to 39 combined mpg driving the downtown streets and freeways their in dallas. Not bad for a car where I had to run the AC during their hot summers. I will add, I always used Chevron regular gas with Techron in it and I always used michelen tires same as I did on the other 3 toyotas I had later bought.
I talked to the lady that bought this car about 5 years ago. She said it now has over 300,000 miles and her daughter was using it in Albuquerque to drive to collage in. I did make her a list when I sold her husband the car. To stay with a top-tier gas like chevron and what weight oil to use. I had put new michelin tires on it and mentioned they should have them rotated and balanced ever 5000 miles including a oil/ filter change.
check this out..
Toyota Camry:
4-cyl 178 hp 6-speed auto 25 city, 28 comb, 35 highway
6-cyl 268 hp 6-speed auto 21 city, 25 comb, 30 highway (in my opinion 268 hp is overkill hp you will never need)
Toyota TCH:
Regular TCH, variable tranny, 200 hp 43 city, 41 comb, 39 highway (156 engine + 44 EV motor = 200 hp)
TCH XLE, variable tranny, 200 hp, 40 city, 40 comb, 38 highway
These engines all run on regular grade gas. The 200 hp TCH with plenty of power will sit you in the seat if you press off the ECO button.
I bought a 2007 TCH and loved it. I traded up to the all new 2012 TCh when it came out. I was always a little jealous of the regular TCH getting a few more mpg than the nicer XLE. I bought the XLE and found if I slowed down my mpg would then increase big time. I have always got around 50 to 52 mpg combined on both year cars. I do live in the high desert of Southern New Mexico near Alamogordo. The elevation here is around 4000 feet and it's usually very dry especially during the summer. I have found the dry air and very little wind helps my mpg plus my slower way of driving so the EV will come on more often.
I don't advice anyone to try driving slow on any busy highway or in the heavy populated cities. Traffic where I live it like driving back in the 70's. I always used the cruise control even as low as 25 mph out here on the 2-mile rough country road to our house.
Some of the advances I can remember on the 2012 TCH is the engine includes a lifetime timing chain. The water pump is a variable-electric to better control the engine temp. The old pump is engine driven variable to improve mpg and better lube the valve-train when you first start your engine or after it auto shuts down while driving. The valves are opened by roller-rockers to reduce friction. The long lasting valve-springs are just strong enough (less friction) to allow the engine to reach just above it's maximum rpm which also helps the mpg.
The aluminum engine uses special sleeves and pistons that run cooler. The advantage here is they can run much tighter piston clearance for long lasting compression, mpg and performance boost over the life of the engine.
The electric steering and braking was improved over the previous models. The traction battery for the '12 on up was made in America by Toyota and it's amperage was also increased. The other traction battery improvements was this new battery has better internal airflow thus runs a little cooler. The air intake for the traction battery fan was moved from behind the rear seat, rear window to the side of the left rear seat to intake cooler air.
The rear seat was moved back some to allow for more knee room. Lots of other '12 TCH improvements I can't remember. I will say I just do not remember anyone having any engine problems with their TCH. The variable transmission is the greatest thing ever. It never gives trouble that I know of and it's just a few gears spinning along with the engine, axles and motor/generators and is fully variable.
The transmission houses two very high quality motor/generators. MG1 and MG2. MG2 is the more powerful one and propels the car and turns into a generator when you coast or press the brakes. Once you get down to about 10 mph then it auto switches to the physical brakes till the car stops. Many TCH owners report very little physical brake wear on the TCH even at 100k to 124k miles.
MG1 is used for backing the car up and is usually charging the traction battery continuously at a low rate. It may be used for forward power but I don't recall reading that. Using Consumer Reports auto magazine from 2007 and have compared the TCH to the Camry engine only version. The TCH each year gets the higher marks for it's quality.
The '12 TCH and the earlier models use 0W-20 oil which being thin improves the mpg and gets up into the engine quicker for less friction. The 2012 XLE offered two versions of navigation. The 7" touchscreen was the deluxe one that had more buttons on one side than the 6" screen. You can see the difference by using goggle images. I think the 7" touch-screen navigation was only offered with the leather trim seats.
They may be other improvements to the '12 TCH, if I find any I will add to this post.
