Oof. 89 required? I've gone places they dont even have 89. 87 minimum acceptable is part of my vehicle selection criteria.

Where are those places? I just came back from Montana and Wyoming, where there is gas station every 70 miles, and all had full range of gasoline octane ratings, even those beaten up gas stations.
Also, any BMW can run on 87 if other types are not available. It is just that BMW wants you to run on higher octane rating, same like ALL other manufacturers would like that we move from 87 to 89 as minimum octane rating.

wow...so there is some secret sauce in the B48 engine... The 42mpg doesn't surprise me at all based on the X1. A .23 drag coefficient is incredible, it's lighter and has 2 drive wheels.

It is modular engine made together with B58 inline 6. I bet 340i returns excellent mpg too, for engine of that size of course.
My wife might get new (slightly used) car next year, and there are only two options: X3 or X5, with B58.

Some in NE Texas, some in Oklahoma. Some in Arkansas. Often around lakes or way out in the middle of nowhere.

I doubt they're much different in their real octane requirements. The CX-5 turbo recommends 93, after all. Since there is no 87 in Germany, I'm not surprised that they have 89 "required". Some though I bet that if you run 87 in there for a few tanks, it won't blow up.

No, it recommends 87-93. 100% happy on either, and advertised as such. It will tune the fuel trim to whatever you put in it to safely get the most out of said fuel.
 
I rented from Hertz a civic 2L turbo in the morning when AC not needed got 51 mpg on one tank, I only drove 320 miles so the fillup was like slighly over 6 gallons, so that small amount there is likley some error. but wow average speed about 75 slight head wind not enough to move flags. With AC was 42. Wow, motorcycle economy, and air conditiong.

I have been throughout various bumblef... in all those states and all had premium. But it is good to know that people choose vehicle bcs. they saw gas station having only 87, somewhere. I have seen actually gas stations that sometimes ran out of gas completely, so you better get electric vehicle pronto with solar panels.

Since when does Hertz rent out Civic Type R? Unless you had the non-turbo 2.0L, or turbo 1.5L... As far as I know (and correct me if I'm wrong) the Type R is the only civic offered with the 2.0L turbo...

I already have solar panels, by the way. I do plan on going PEV as soon as they have some reasonable range to them. For example, today I drove about 250 miles. Most of the Tesla's are only rated at 300ish miles.

That said, most modern vehicles can self-tune to run on 87-93. Why select one that cannot?
 
I opened the hood, sticker said 2L turbo. I know for a fact it was a turbo. It was not a type R. It had a CVT and ran pretty darn good.

I do not even know what year it was. Had about 35K miles on it, and very little tread on the front tires.

I was impressed.

My R "requires" 92 octane. Half of my driving is in CA, where you can't even get 92 octane... I bought it because 1) I'm pretty sure it'll still run fine on 91, 2) in close to a million miles of lifetime driving, I'm only seen 1 or 2 filling stations in the US that don't have at last 89 octane.

Based on the above, having a car publish that it can run on 87 just isn't a requirement for me.

The transmission is pretty good. The engine is low tuned in this app. Guessing they went max fuel economy in every engineering parameter.

Our TourX has a similar if not identical trans, curb weight, 2.0 turbo, getting 35 highway can be done if conditions are right. Seeing 37s in a taller crossover is way good. I am even more surprised you made it that far with the power windows still functioning! Just kidding
 
Nope.

If You’re sure it was a Civic, and it was 2.0L, it didn’t have a turbo.

There are only 3 engines available in the Civic - 2.0L (NA), 1.5T, and 2.0T.

As others have said, the 2.0T is only available in the Type R, and it’s 300+ HP.

If you saw "2.0L" and it had a CVT - you did not have a turbo version. If you saw "Turbo" and had CVT - then it was a 1.5T. If you saw "2.0L Turbo" and CVT - you have been fooled by an Accord that had a 10-speed automatic transmission.
 
OK, I did not look at it long. It certainly looked like it had a turbo.

The rental receipt said Civic 2.0 only.

I did however look at the oil. Which was as black as natural crude. I suspect it had been quite a while.

When you floored it, there was a lag, maybe it was simply the CVT shifing the pulleys.

Ir was NOT 300 horse, but it had enough to be entertaining.

The BMW B46/B48 engines are extremely efficient. I had a 2020 330i loaner and it returned 45 mpg driving to work and averaged over 36 mpg for the two days I had it- that's about as good as my smaller and MUCH slower Clubman.
 
I believe BMW gears their cars pretty well for highway use. I used to get 30 mpg with a 330xi cruising around 78 mph.

the x1 is basically a bmw styled Mini Countryman. The gearing really helps the engine stay at low RPM.
