A new BMW sport-tourer, the M1000RS, has come to light through a filing with the California Air Resources Board. It reportedly uses the M1000RR's 999cc ShiftCam inline-four making 215bhp and chain final drive, marking the first RS model to break from BMW's traditional boxer engine.
This is coming from a CARB filing rather than a real spec sheet, but 999cc across four cylinders for 215bhp already gets my pulse up. The RS line has always been a boxer, so chain-drive inline-four showing up here is honestly unexpected. Dropping the M1000RR's ShiftCam straight into a tourer shows real intent — that's the good part.

What kind of tech is ShiftCam exactly?
It's a type of variable valve timing, one BMW's really invested in.
For the same money, why not just get the S1000XR?
Source is a CARB filing, so nothing's confirmed yet, right?
Makes sense to see 215bhp if it's the M1000RR's 999cc unit.
Honestly surprised the RS is ditching the boxer.
