I wondered how those NASCAR Camrys got that much speed and power from the 3.5 V6. Must be the racing gas. lol

Just got off the phone with my brother. I had taken him down last Friday to pick up his new Prius Plug-in and he was giving me a summary after driving it to work all week. He said that he had driven 390 miles and had used 2 gallons of gas (195 MPG). As he has gotten used to the car his mileage has come up and he said he has gotten 221 MPG for the last four days. He does have a level 2 charger at both home and work (employer supplied). These numbers include about 15 miles that I put on the car driving it around last weekend without trying to do anything special (but, I was primarily using it in electric mode). The car did report that he had used about 50 KwH charging the car at home, work and while shopping. Anyway, I thought it would bring a little perspective to the regular vs premium discussion ....

221 mpg doesn't mean anything to me when it does not use gasoline. It is a meaningless number any way I look at it. Plug-in cars burn mostly coal, natural gas and nuclear. I would have to see the payback on the additional investment for tha plug-in when he could have bought a Corolla for about $15k. In my mind he paid a premium near $16k plus taxes and interest. If he lives where he can buy electricity cheap it might not take as many generations to get a payback. The only way plug-ins are going to be attractive is if the utitlity industry builds additional power plants that produce low cost power, and that is not happening today.

Positive Crankcase Ventilation by way of piston. See also, half of Kasey Kahne's motors this season.

Tweaked for premioum fuel with 92 octane and a 10.8:1 compression ratio and equipped with a modern engine management system that incudes knock sensors, higher than 87 octane will buy you some extra power in these cars. You shouldn't need an automotive engineering degree to appreciate that.

But don't expect the difference to be like day and night. Most drivers can't notice a 10 or 15 HP difference with a 275HP engine in a 4200lb car. On a track on a very hot day, it would make a difference but for the way most people drive, it does not make for a noticeable difference.

Pretty good, I got five pages of posts and I was only asking about 5 horsepower!

OK, I can answer your initial question on this thread, and the answer is a resounding, maybe.

Seriously, I thought it was interesting while looking on the Hyundai Genesis web site, that for the 4.6L V8 they show the horsepower and torque ratings for that engine using both regular and premium unleaded. The hp difference in that case was 7 hp (385/378).

That helps to take some of mystery out of things.

Now that is a good answer backed by a manufacturer!

In CA you can get a special electric meter if you have an electric vehicle. If you charge at night before going to work, it is 3 cents a KwH. Basically, next to nothing. But, here in the San Francisco bay area there are charging stations at work and shopping locations which are free to use. There are smartphone apps that show the charge locations and if they are available. Many charge stations allow you to check your cars charging progress on your smartphone and will alert you when it is charged. So most people are not paying for all of their charging. It is very economical. My brother also got a $1,500 rebate from the state of CA for the car purchase.

But, to answer your question. In the first week it took 50 KwH (this is what he told me...but, seems low) to charge is car for the 390 mile range he drove (plus 2 gallons of gas). If we round this to 400 and he drives 1,600 a month (19,200 per year), he would need about 200 KwH of charge. His employer and many of the stores he shops at are picking up some of his charging. So lets assume he pays for 125 KwH at 3 cents. That would be $3.75. I need to check with him and look at the stats in his car to confirm my understanding of the amount of electricity needed to charge the car because this just seems very low. This has been a leaning experience for me (a good one) and so don't quote me on the charge amount until I can confirm the correct number. But, as you can see it is economical. In discussing it with him earlier today, he indicated that he was not concerned about it at all.

Also, for a while plug-in owners can use the commuter lane with only a single driver (if you have a DMV tag). For some, this is a very valuable perk.

the comparison cannot be judged accurate since the original poster did not provide colors of either RX, and what he and brother-in-law use to wash their RXs becaue one of them can have less drag then the other...Perrier wins over evian me thinks...

Wow, somebody must do the task and put this subject to rest. That is a big different.

How could the TQ is higher than the HP since they are originally opposite? Dinh, is that a typo?
