I have to agree. That time seems a ways off. My best time so far on Laguna Seca in my modified C5 Z06 was 1:50.1. It was the first time I took the car out to the track and I didn't come anywhere close to the level of grip and speed in the corners I should have, but I wasn't necessarily a slow poke, as I was passing plenty of people. I should be able to shave 5 sec off next time I go.

They're using their cell GPS to gauge time. I have the latest and greatest Samsung Note 5 and use the GPS mapping to time my walks and jogs. It's horribly inaccurate and inconsistent when you look at the data. They need a real timing transponder for the track. I call BS on the 1:40.88 time. This car definitely is not beating out a C6 Z06 Vette, Cayman R, and C63 AMG S at the hands of Randy Pobst.
Correct. ALL cell phone gps refresh at 1hz, or once a second. That leaves a lot of room for variability.

You don't think 1 second slower than the M4 is feasible?

I do. I think the GPS isn't great but the timer should be dead on, right? it might lie about your pace around the track but if you start/stop on the start/finish line I'd think it's basically like using a stopwatch.

not the same as going for a jog, waiting for it to hit 3.1miles then checking the time to see what your 5k time is.. i.e. it might say the lap was a few tenths of a mile longer/shorter than actually traveled, but the time should still be accurate.

I'm not an expert but that adds up to me. I do, however, want to see what Randy can do with the M2. maybe they'll do a M2 v. M4 head to head.

He already did an M2 vs M4 head to head, unless you mean on Laguna Seca.

People don't understand what driving skill can do. My friend ran 1:47 in a bone stock 2015 WRX on stock street tires. A modified C5 Z06 with a good driver will be easily sub 1:40.

1:40 is very quick but looking up official laptimes it is 2 seconds behind a GT4.

I bet Randy beats this time during this years Best Driver's Car competition. Randy is a really talented driver, he will be able to prove it soon.

Interestingly, while we were doing auto-x at the Thermal Center a couple weeks ago, Both I, and my brother set our fastest auto-x times with the other person in the car. We were both a couple of tenths slower without a passenger. Not that either of us are highly consistent, but it was interesting.

Yeah, I'd be disappointed if I were saddled with more than 800 extra lbs too. :P

At 10/10 not possible though.

That's because it hauls ass on all those long straights.

Randy Pobst obviously is the more experienced guy at Laguna Seca vs Martin Tomczyk. But Martin as a DTM 2011 champion knows what he is doing too

So two different drivers, GPS malfunctioning so-they-say, slower than an M4, faster than an M3 E92. Almost on par with a 560BHP supersled M6.
AND with 2 persons aboard...

It always will be an apples to oranges game. Always.

I find this video the most amusing of an M2 so far:

-Entertaining and some info like pulling 1.6G(!) in the Corkscrew on 'streettyres'.

-Laying down 90 metres(yards) of rubber down a B road in a long drift.

-8seconds staying in a drift on a dry Laguna Seca in a non modified car.

-Donuts galore

-Dat sound!!

Off course this is probably not the most useful information for a 'car test', but what are we looking for in an M2 anyway? MPG? Luggagespace? Parking Assistance?


Cheers
Robin

Would need to see same driver driving Cayman GT4 and see what his lap times are then

So you're saying that you're capable of a running 1:45 on your second time on a track, but then you call BS on professional drivers that can be 5 more sec faster, all of whom have countless more hours of seat time and skill than you probably do? :

S65?! Should be lighter, closer to the firewall and lower than the S55.
