Looks like fun! Is it for use in sand dunes?

Did you even read the linked article? Either you didn't, or you're just grasping at the straws for anything to support a point that really has no relevance.

Of course racing technology comes down and can be used to improve street cars-that's been true since the beginning of automobile racing.

It doesn't change the fact that you keep asking why street cars can't get the thermal efficiency of an F1 engine.

Racing engines are NOT street engines. If I could put that in bold 50 point font, I would. That's true of any racing discipline. As I've mentioned numerous times(and I'm not sure if this is even registering with you), F1 engines tend to have extremely short strokes(they are "oversquare" meaning the bore is much larger than the stroke). A short stroke engine is inherently quite efficient as it minimizes the frictional losses from the pistons moving in the bores. Short stroke engines also tend to be able to rev to very high rotational speeds. As engines tend toward oversquare designs, torque at low RPMs suffers. This is a common criticism of Japanese engines, which tend to also be oversquare, although not to the level of an F1 engine. Most people don't want to have to rev their engine to 8K rpms to get any amount of torque from it. This is in contrast to your typical "square" American V8, which is a design known for low end torque.

Second, common to most racing disciplines, you have very high compression ratios. It's become expected even for a lot of economy cars in the US to have to use 92+ octane(r+m/2), but when you get into the range of 14:1 or better(NA), or crazy boost pressures, you start needing 100+ r+m/2. That's not practical for street use. Although F1 doesn't allow it(nor does NASCAR anymore), some racing disciplines still allow leaded gasoline, which is a quick and easy to get those kind of octane ratings-of course that's illegal on the street AFAIK in most if not all of the developed world.

Again, races cars are NOT street cars. Your typical F1 car is going to spend a good portion of its time at or near its top speed. In pretty much all types of racing, you're making the assumption that you spend a good portion of your time at or near WOT. Things like camshaft profiles can be optimized for these conditions and both give crazy amounts of power as well as high thermal efficiency, but it's useless for driving on the street. This is at the other extreme of the technology spectrum, but with an aggressive enough cam profile I could probably easily get 50% more peak horsepower out of the tractor engine in my MG without changing anything else, but I'd also have a car with a rough 2K idle and with no guts below 4K.

Finally, racing engines get more attention than any street engine could ever hope to get. It's nothing for an engine to get torn down after even just a few hundred miles. A racing engine might have an expected life of 5000 miles or less. Now, people get upset if a car engine doesn't make 250K with nothing more than an occasional oil change and maybe some spark plugs every 100K. You can do thing to increase the thermal efficiency when an engine gets a level of attention that is not practical in a street car.

The more you babble on about this, the more I'm convinced that either you really have no clue what you're talking about, or just like seeing yourself post endlessly.

And to close this out, if I haven't made this abundantly clear, RACE CARS ARE NOT STREET CARS!

What an informative post. A F1 engine has such tight tolerances that they won’t even turn over without heating up the oil first! Plus you can’t start it without additional external equipment.
Probably wouldn’t work out for the daily commute!

Nope. This is for street use. Street legal.

You keep arguing beside the point just because you hate me.

How was that post "beside the point"?

You keep posting nonsense when you clearly don't know what you're talking about.

We get too much rain for it to be a daily driver here! Anyway still looks like fun.

Love those wheels.

Thanks. It stays in the garage most of the time. Got it out yesterday since the weather was nice.

My 2015 Fit got broadsided in July 2018.

Sorry to hear that. Were you guys alright? I now remember why I don't remember reading that because I was away for most of July. What did you get with the insurance payout?
[doublepost=1555980035][/doublepost]

I don’t know, probably a result of a marketing think tank.
But if you are looking at efficiency you are probably not looking at a Mustang. Probably a Prius or something (yuk).

The only benefit I can see to getting a Prius is that some models do or did come with a solar panel to charge the vehicle's batteries when it was parked outside. This also allowed for the aircon to work during the warm day and keep the interior nice and cool.

That is awesome. I would so drive that. What motor is in it? I have seen some with some pretty wild builds. Saw one on the dyno that was making 148 Hp. Yet it was very quiet. I am sure it would surprise a few people.

A Prius just wouldn’t work for me. Apart from the efficiency, it’s an ugly car.

A hybrid will make sense at some point, but as someone who keeps his cars a few years I’d be worried about battery life. The minute your old battery stops holding a decent charge, your carrying around a big (literally) dead weight.
That’s not going to help with fuel efficiency.

Of course you could get the battery replaced but that’s expensive.

Are rebuilt batteries not a thing? I'm not a fan of hybrids or electrics. Correction, I like hybrids that make things go even faster than a pure ICE counterpart.

Check out the new Honda Insight. It’s a good looking hybrid. This is ours....

What's that hunk of plastic underneath the side mirrors? Squarish in shape and not contoured.

 

[AdamNC]

Its the bottom of the mirror. It does have contours. Just not a very good pic. Here’s one I took tonight.

Probably but I’ve never really looked into it to be honest. They are more expensive than I tend to want to spend.

Yes that certainly looks more attractive than a Prius.

 

[0388631]

Must have been the angle then. Eh, there is little to think about these days. Toyota may have better resale than Honda, but Honda offers more standard and at each tier. Though it'll be a while until long term reports of Honda's turbo engines come in.

 

[AdamNC]

The motor in the Insight is not turbocharged. It’s the same 1.5 liter as the turbo minus the turbo. We average 49 in town, and the few highway trips we have done we have seen an average of 59 mpg. That’s with cruise control set to 75.

 

[0388631]

I was speaking about their general cars since he wants to avoid a hybrid because of down the road the hassle. Think you mean mpg, though?

 

[AdamNC]

Also ours is a EX. It has the Honda Sense Package, Lane keeping, auto LED headlights, pacing cruise control, navigation, Apple Car Play, etc. $25750. Not bad for the price.

Yup I meant mpg. My friend is a Honda tech. He has seen a few of the 2016 Civics with the 1.5 turbo with 85k on them and zero issues so far. Like any Honda if you maintain them they will last damn near forever.

How many HP is your Golf?

 

[Apple fanboy]

How many HP is your Golf?

120. More than enough for my daily commute.

120. More than enough for my daily commute.

Yes, that is the minimum I look for. Enough for going on holidays to the mountains.

 

[bunnspecial]

Hmm, never knew my 90hp(gross) MG wasn't suitable for driving in the mountains. I guess I won't drive it down to Eastern KY this spring like I have for the past few years since someone on the internet told me that wasn't enough power to drive in the mountains.
