I hit 105 in my 1.8...but who knows, if you are going down an incline and have the room to get it going.

Stock, flat out on a flat mine did 123 Haven't been able to get a open road since I modified it to run it flat out again

But I can tap 110 pretty quickly anymore. Probably do it once ever few weeks or so

I did 125 in my modified 1.4T, but that wasn't my top speed, in fact I had no real sensation of acceleration dropping off, I'd say the top end would have been substantially higher. I just had to back off because the taillights of the car ahead were coming up fast. Need a closed track with a lot of straightaway to really find out the top speed, if I'm gonna be the driver.

146mph

146mph

That is probably downhill lmao

I've hit 130 on a flat but it won't go any further. Plus redline looks to be around 150-160

I remember seeing a RPM to gear graph that put the 1.4 at 206 mph

Could be wrong

With the redline at 6.5k thatd be crazy to see lol

The top speed for all sonics is drag limited ~124 mph for all trims and options. This can change slightly based on conditions, wind, and grade.

Increasing power will increase the top speed. top speed will be reached in 4th or 5th gear. The highest confirmed speed for a modded sonic is 141 mph.

The theoretically top speed for a 1.4t w/m32 trans is 217 mph and would require in the neighborhood of 800hp to achieve that speed. Linkhttp://www.sonicownersforum.com/forum/1-4l-turbo-sonic-engine-discussion/640-sonic-geared-217-mph-lol.html

But from what I've seen the speedo stops going up at 168 mph.

206-217. Close enough. 200 something.
