First Drive: 2010 MTM Audi S5 Cabriolet

As delivered by the factory, Audi's S5 Cabriolet makes for a charismatic convertible. Although lacking the V-8 grunt of its fixed-roof sibling, it offers an enticing combination of power and style, yet is comfortable and benign enough to use as a daily driver. Is there any way to improve upon Ingolstadt's invention?

Moteren Technik Meyer, or MTM, certainly thinks so. The heralded German tuning firm feels a few subtle tweaks can turn Audi's shapely roadster from mild to wild.

European Roots
Unless you're a dyed-in-the-wool Audi buff, chances are you've never heard of MTM. That's understandable -- until recently, the company had made few inroads to the American market, a situation it's working to change, by signing up additional distributors in North America.

But MTM didn't start swinging wrenches yesterday. Founder Roland Meyer established the firm back in 1985, and MTM has worked on improving Volkswagen/Audi products ever since. MTM's projects have included everything from converting U.S.-bound A3 hatchbacks into S3s, packing two engines into an Audi TT coupe, and preparing turbocharged Audi five-cylinder engines for the limited-production Ital Design Aztek roadsters.

MTM's S5 Cabriolet package is, however, somewhat unusual. In a break from tuner tradition, this isn't an over-the-top, in-your-face showpiece designed to wow auto show crowds and scorch retinas. Instead, MTM adds an extra dollop of power and some minor refinements without disturbing Audi's original recipe.

Chipped, Slammed, and Dressed Up
Arguably, the most significant modification lurks within the electrical system. MTM's M-Cantronic engine controller contains the recalibrated engine computer mapping that allow drivers to explorer new frontiers with Audi's supercharged 3.0-liter V-6.

In stock form, the 3.0T engine produces a commendable 333 horsepower between 5500-7000 rpm, and 325 pound-feet of torque at 2900-5300 rpm. Install MTM's tuning module and a new exhaust system, and those figures jump to an impressive 430 horsepower and 379 pound feet.

I can think of a LOT of other two door convertible vehicles I would rather own for a price tag of $95K. All of them capable of matching or besting the performance of this modified Audi.I think you guys nailed it right on the head. I too think that with 4WD and 430HP, launch control should give you Panameraesque performance off the line. I think it was a missed opportunity and would have cost a lot less to implement for the payback in potential performance.
