BMW 0-62 times are very optimistic. The 2.0 MX-5 which is only 13bhp down but a massive 300kg lighter, is officially only 0.1 quicker to 62, don't think so.
I'll wait for a proper timed test in Autocar ( maybe EVO ) but I think the new Z4 could do those numbers.An E36 328i manual Touring, smidge less power and torque and same weight managed 60 in 6.1 and 140 on the Millbrook bowl. Proper timing gear, driver and passenger, half tank of fuel. The saloon managed similarly good times
I'd say it would have managed 62mph in the extra 0.5 seconds.
Testers usually reckon you can add 3/4mph on to the speed bowl Vmax ( when taking into consideration tyre scrub ) for a straight line speed
The old Z4 2.5 manual with 189bhp and 1335kg ( similar power to weight ratio as this new one ) was timed at 6.6 to 60 and 149 max on the bowl.
A fast shifting modern auto allied to plenty of tyre grip/modern DTC etc might well shave a couple of tenths off the acceleration times so I think they could be realistic figures

Seriously!
197BHP!
BMW! This shi@ is so simple. 30K - 32K 350bhp C'Mon what are you doing! This is another missed opportunity. Look at what you did with the M140i Wake Up!

Er, you are aware they are making a version with the M140i's engine and that most one series have small and or diesel engines ?197BHP!

Its the entry level engine for those that can manage with 197 bhp, a lot of those will not be bothered one iota, can understand why anyone gets so offended by a car that isnt of interest to them, I cant abide Prawn Cocktail crisps but the presence of them next to the Cheese and Onion doesnt bother me.
I just did 231 miles in a Skoda Octavia with just over 100 bhp, and it was fine, so 197 would be quite adequate, more is better but it will still be plenty fast enough for those who buy one, if it isnt there are currently two notches above it.
PH is screaming for a "lighter" less powerful, cheaper version of these sports cars and this is what they get. It's working because people are comparing it to the MX5.
Of course, price-wise, you pay a premium for the badge.
This is the entry level and the reason I can see why it has such low power for 2 litre turbo is that it gives a good marketing platform for BMW.
They can then price up a 250bhp, 300bhp and 350bhp version. And then once all that's done, they can then rinse you with a 400bhp ultimate version.
Once the face lift version comes out, they can slip in between the market niche and introduce 225bhp, 275bhp limited edition versions.
All this with the same engine in different state of tunes. Add in a few "sporty" trimmings to differentiate and uprated brakes and suspension and voila.

Take modern day diesel turbos with 8 speed gearbox. Performance is up there with the high volume petrol engines of the past.
It's the transmission with high number of gears using a narrow bandwidth of the rev range which is giving this performance. The Z4 will be always within 80% of max torque throughout that acceleration cycle.
In addition, BMW have really mastered the speed and smoothness of these gear changes which adds to the 0-60 performance figure.
