Perhaps, but in the meantime, BMW's M performance division has listened to its customers attentively, and here are the most recent results: the X3 M and its coupelike derivative, the X4 M. At 473 horsepower, they are positioned well above the current range toppers, the 355-hp X3 and X4 M40i. And because too much is not enough, BMW is giving us Competition versions as well. Their engines are rated at 503 horsepower, and they are available right from the beginning.

This awesome power is delivered by the newly christened S58 engine, BMW M's derivative of the corporate B58 engine. But it's bored out and comes with a shorter stroke (losing a precious 5 cc of displacement in the process), and the M division has touched simply everything to turn it into a loud and high-revving powerhouse. Both engines produce maximum power at 7300 rpm, and the maximum torque of 442 lb-ft is served up from 2600 to 5500 rpm (5950 for the Competition version)
Force fed by a pair of turbochargers, the S58 is fitted with a forged crankshaft and a DOHC 24-valve head featuring variable intake- and exhaust-valve timing and variable intake-valve lift. It sends its torque through a ZF-supplied eight-speed automatic transmission that shifts so quickly, you won't miss a dual-clutch box (but perhaps a manual). According to BMW, zero to 60 mph happens in 4.0 seconds for the Competition (add a tenth for the regular X3 M and X4 M), and top speed is governed at 155 mph but can be raised to 174 mph on the regular models and 177 mph on the Competition models. Official EPA fuel-economy estimates are still pending, but BMW M promises very reasonable figures.
