So I bought my first smart about two weeks ago brand new with 30 miles on it and I have 600 miles on it right now (wasn't planning on driving it that much as my motorcycle is my main form of transport but the weather has been like crap the past few days). I know most people only use the smart as a city car but I live in south Florida where it is very spread out in most places except deep downtown in the big cities like Miami, Ft Lauderdale etc so most of my driving with it is on the freeway. Everyone assumes the car is too underpowered/light to go on the freeway and that it gets pushed around by the slightest gust of wind but that's not true at all that's deeply exaggerated. Sure you definitely wanna make sure you have both hands on the wheel as sometimes wind can push the car ever so slightly (yet it handles wind better than most high profile vans/pickups that I've ever driven) but it's not like you're riding a 200 lbs 125cc 15 hp motorcycle (been there done that once scary stuff had no choice had to ride it home on the freeway even though THAT was a city bike). The car has no problem getting up to speed on the highway or merging it tops out at 89 (more than enough since speed limit is 65 even tho most drivers where I live do 75-80). Now my concern is I heard I have to go easy with the car for the first 1000 miles to break the engine in and I don't know if I've been driving it properly. For the first few drives I had to learn the transmission and figure out how to shift properly in manual mode (I'm not gonna lie automatic sucks I stick with manual one cuz it's fun and two cuz it shifts wayyy better I believe it's meant to be driven mainly in manual). On those first few drives, I went a little rough with the rpms until I figured it out and I'm worried that I'm going too hard on the car cuz it has to be broken in. I don't have the nice tach/clock add on that comes with some smarts but I'm planning on getting one soon so I can have a better idea of my rpms and don't have to turn off the radio to hear how high they are. Long story short (not really short I wrote quite a bit I know but short-er), I'm worried that I have strained the engine by going top speed with it on the freeway and from shifting at high rpms. I've always found it easier just to put my pedal all the way down on the freeway as the car has no cruise control which I really don't need because it tops out at 89 which is fast but not so fast that I have to worry about slamming into cars ahead. I tried to drive it as smooth as possible at first but I had to be realistic I couldn't drive like a grandma because I had to keep up with traffic the car has plenty of power to keep up and even pass but it needs the rpms to do it. I just want to make sure I didn't mess up my car's engine in the long run and have to deal with problems down the road as I know the little 3 cylinder engines with a computerized clutch are delicate but I have no idea just how strong/reliable the powertrains are and how much they can healthily withstand. I just want some reassurance and knowledge from long time smart owners as I'm still a newbie to smarts after wanting one for so long and finally being able to buy one.
