G20 330i vs F30 330d

[3 serious]

You can use an aggregator site, but think about what it is aggregating:

Publications test at

different altitudes
different fuels (and tunes of the car for such fuels eg: Audi S3 in SA or Subaru STI)
different temperatures
different versions of the same car (EU4/5/6 emissions, hot climate etc)
different drivers & testing approaches

They are given press tweaked cars in many cases (though probably not for these kinds of cars granted)

There is also the volume of data points for each car (you might have 100 for an M3 or 911 Turbo S hypothetically with actual testing vs. half for another type of car). There is also media bias in these tests where some (admittedly) will try HARD to get a good set of numbers out of one car and will barely bother with another. There is also the advertising politics at play... let's not start with that can of worms.

Also some just regurgitate the press release numbers and will also be captured.

So sure, use it as a guideline or starting point, but that doesn't solve the problem and anyway that isn't how statistics work. A huge amount of aggregated but disparate information doesn't automatically make it valuable statistically.

This is why I value Mark Jones' test results for Truespeed as all are done at Gerotek with very strict test criteria.

There is some truth in what you say. However: most of the points you raise can affect either car. Altitude, fuel, temperature, different versions of car and emmisions standards, press tweaked 330d or press tweaked 328i. Media bias and advertising politics can't affect much here since both are f30 BMWs. G20 330i seems to be very close to f30 330d though, but averages say 330d is just a bit faster. I prefer averages from different reputable sources than 2 or 3 races between friends or what one journalist posts on their site. 328i can definitely give a 330d a serious race but from my personal experiences the 30d is almost in the league of 335i, especially below 200km/h.
Back to OP,  f30 330d vs g20 330i will be really close in terms of speed. I wouldn't choose either based on speed but other things like petrol sound, newer car in 330i, superior interior etc. F30 330d will surprise many such as GTI 7 boys trying to race you. It is also more efficient and more reliable from what I have seen and read.

At a rolling start, I figured this chap wanted to dice as he kept beside me, Robots ahead were Red... Watched the other set of Robots which turned Amber.... Sweaty Palms.... Switched her into SPORT+ ... Flicked the Gear Lever... Flicked the paddle to shift one gear lower...Gripping the steering wheel tighter...

LIGHTS TURNED GREEN

Stepped on that kickdown, bulleted for about 2 -3 seconds with him at my rear tail and then the moment my 30d was null & void... He jetted about 4 - 5 seconds ahead of me.... GP - plates .... Im assuming it was tuned, I've been in a 7R and that GTI was making my 6 pot look like a 2-stroke :fencelook:

Lol hahaha! Sorry mate. Definitely tuned. Im guessing yours is stock?

Yes, still stock due to extended Motorplan.
