If there’s a midsize sports sedan standing above the rest, one could argue that it is BMW’s 5-series. So we thought it critical that we spend a year with one.

2011 AC Schnitzer 99d – Click above for high-res image gallery

AC Schnitzer has showed up at the Geneva Motor Show with not one, but two fresh-off-the-press upgrade packages for 2011.

Not wanting to look completely unfriendly to Mother Earth, AC Schnitzer has taken their expertise to the Z4 and BMW’s EfficientDynamics system, working over a 320d mill to go under the Z4′s hood. The 2011 AC Schnitzer 99d gets a 70-hp boost to 190, hits 60 in 6.9 seconds, releases a scant 99g of C02 per mile and returns a handsome 63 mpg in the European cycle. That, according to Schnitzer, is better than any BMW on the market. Unfortunately, the 99d is just a concept, and won’t be available to the public any time soon.

For the family minded executives attending the show, AC Schnitzer started with the 2011 BMW 550i, bumping the car from 407 to 540 horsepower. According to Schnitzer, the result is a 4.5-second 0-60 sprint and a whopping 198 mph top end. The engine exhales through a new set of the tuner’s own mufflers capped with chrome surrounds. The resulting executive express has been dubbed the ACS5 Sport S.

Hauling all that energy to a stop is a revised set of brakes sporting eight-piston calipers. Outside, Schnitzer went all-out to ensure that the car would be stable at its newfound velocity. The laundry list of exterior mods includes a front spoiler, carbon ducts for the brakes, new engine bay vents and, of course, your choice of 20 or 21-inch AC Schnitzer custom wheels.

Check out the official videos and press releases after the jump.
