Other US sources are available.
So gearing, marketing or something else?
Don’t Americans measure from a rolling start?
That’s my understanding as well , as far as I’m aware the engine and gearing are the same.
Hmmmm…
That’s confusing.
See the test data from roadandtrack. They do show the rolling start and a 5-60 time of 7 secs. Plus they also show a 0-60 of 6.1. Plus data on revs for best launch.
So how does their rolling start measurement work? Do they roll slowly forward to a Mark and then boot it? In which case it’s not really “0” at the start?
I think it’s similar to drag racing which I know nothing about but essentially your starting the clock once the front wheel has passed through the timing beam, this distance I believe is called the roll out either way the car is moving when the timer starts.
0-60 and 0-62(100km/h) are often totally different, if there is a gear change at 61mph. Some companies gear their cars to get around this . There is also the rolling start procedure in USA but no way does a 2.0NC Sport take 7.9 to 62 when a Lotus Elise takes 5.9 to 60, i’ve driven both, gap is a lot narrower.
I’ve seen US quotes of 170 bhp for the 2.0 NC, we get 158 bhp.
The US measurement excludes power used by auxiliaries.
See wikipedia under horsepower.
There’s not that much different between SAE and DIN.
EU MZRs and US autos both had Variable Tumble Shutter Valve (VTCS) before 2008. US manuals did not.
