There wouldn’t be much of a Geneva Motor Show if AC Schnitzer didn’t have a thing or two up its sleeves to announce. For this year’s show, we now know they’ll at least be debuting a new ACS 5 Sport S and 99d vehicles, based on the BMW 550i and Z4 respectively. With both priced at the same amount, approximately $205,785, it probably comes down to if you want a nice sports car or a sedan.

Not exactly falling in the category of cheap, let’s take a look at what you get for your money from AC Schnitzer. The ACS5 Sport S, based on the BMW 550i, has its performance enhanced to 540-hp and 553 lb-ft of torque. A limited slip differential upgrade also comes with the engine modifications. No more details are given on the ACS5 Sport S, but clearly AC Schnitzer will also outfit the vehicle’s exterior with its traditional body kit, trunk and roof spoiler, suspension modifications and a set of fashionable AC Schnitzer fashionable wheels.

The same probably goes with the 99d, based off of BMW’s Z4. For its performance, AC Schnitzer sent the unconventional route and based it off of BMW’s 320d Efficient Dynamics Edition powerplant. The result is 190-hp with 310 ft-lbs of torque. The aesthetics feature much flashier graphics than the 5-Series counterpart does and we’re better ACS has an announcement to make about having your sports car and being green.

Set to debut in Geneva, we’ll be on hand to bring you more on these cars with show coverage starting March 1st.

Oh AC Schnitzer, you’re actually late to the party this time around! BMW‘s new 2011 5-Series has already been overhauled by quite a few tuners including 3D Design and Lumma Design and now the brand synonymous with BMW customization over the last few decades has embraced BMW’s new sedan.

Apparently this is just one of several tuning packages AC Schnitzer has in the works, which makes sense considering this is just a conservative lip kit. We’re going to guess that they’ll come out with a full front and rear bumper replacement in the near future. But as always, AC Schnitzer outfits the 5-Series with an add-on front lip and add-on rear diffuser (to the OE bumpers) along with a set of side skirt extensions sporting a classy chrome blade. Both roof and trunk spoilers are also available with the trunk spoiler carrying a much more conservative design than we’re used to seeing from AC Schnitzer.

An ECU upgrade is available for the 530d bumping horsepower up from 245-hp to 286-hp. And of course an exhaust system is available for all the various 5-Series models. AC Schnitzer did want to express that they’re currently working on ECU remaps for the other BMW powerplants.

Suspension and brakes are also handled by AC Schnitzer, offering a very mild 1-inch drop along with a massive 8-piston caliper brake setup with cross-drilled rotors. (We’re assuming that the upgrade is for the front, while nothing was mentioned for the rear. We can’t imagine having 8-piston calipers in the rear on a 5-Series, but we guess it’s possible.)

AC Schnitzer also has a large assortment of wheels available for the 5-Series from 19-inch to 20-inch variety.
