BMW says its latest two door will hit 62 mph from standstill in just 5.3 seconds and extend all the way to an electronically limited 155mph, placing the 135i on a par with the substantially more expensive Porsche Cayman S for outright acceleration. (autoweek.com)
The result is class - leading acceleration and efficiency with the 320i Touring sprinting to 100km / h from standstill in just 7.5 seconds whilst sipping a mere 6.2 l / 100 km and emitting 145 g / CO2 per km. (ausmotive.com)
A lot of bikes feel like the rider is being cooked at standstill in summer so if all the fluid levels are OK and it's not misbehaving in any other way, it's probably fine. (mechanics.stackexchange.com)
