First Ride: 2015 BMW M3 and M4

Getting Our Butts In The Seats
Both the non-M BMW 3 Series sedan and 4 Series coupe have so far brought much pleasure to us at Autoblog. The terrific four-cylinder 328i trim has become our favorite of the 3 Series line, while we have yet to get a chance at the 428i coupe. That said, the 35i trim powered by a 3.0-liter TwinPower Turbo inline six-cylinder engine is not exactly to be sniffed at.
We all know the ones you're really waiting for, though. The F80 fifth-generation M3 sedan and the supremely sexy F82 M4 coupe. Rumors have been buzzing for a couple of years now that the engine would be another V8, only turbocharged this time, or else a tri-turbo six. Well, today BMW confirmed that the mill under the hood's power bulge is a 3.0-liter inline six-cylinder TwinPower Turbo of the biturbo variety, referred to internally as "S55B30 variant."

2015 BMW M4 Coupe

Launched out of the seat by a huge, unexpected dip in the road, yet still held largely in place by the smooth webbing of my safety belt, I clench my teeth waiting to come back to earth. A tenth of a second later, the M4 Coupe touches down and my body is slammed into the leather seat cushion. All of the air is forced out of my lungs upon landing, but the BMW's chassis, suspension and steering appear unfazed. Pleasantly surprised, I mash the accelerator to the floor in giddy pursuit of the car in front of me - an absolutely identical 2015 BMW M4 coupe.
A cavorting game of cat-and-mouse on a desolate twisty canyon in southern Portugal is an excellent way to explore the real-world driving dynamics and performance of BMW's all-new M4 Coupe. But to truly push it to the limit - without having to worry about oversize depressions in the asphalt - requires a dedicated racetrack. Graciously, my hosts have rented the famed Autódromo Internacional do Algarve racetrack, or Portimão circuit, for an afternoon of automotive debauchery.
It's hard to believe this passes for work.

2013 BMW R1200GS and HP4 duel at Circuito de Almeria

The 2013 BMW HP4 is the track-ready version of the manufacturer's already mighty S1000RR, which puts the bike at the very tip top of the two-wheeled BMW food chain. The R1200GS, meanwhile, is intended to be a somewhat more utilitarian machine. Capable of conveying both rider and gear over vast distances and uncertain terrain, the big-boy GS is the Swiss army knife to the HP4's rapier. Or at least that's what we've always been led to believe. BMW recently rolled out some footage during a press launch that showed the R1200GS is actually no slouch when it comes time to sling around a road course.
The company threw both bikes on Spain's Circuito de Almeria for a little sparring match, and miraculously, the HP4 didn't just up and walk away from the R1200GS. From from it. Instead, the two stay tightly matched through most of the course before something surprising happens. We won't spoil the ending for you. Is it possible the rider on the HP4 still had some in reserve? Sure, but from the sound and look of things, neither bike was giving an inch. Check out all the video action below for yourself.
