The M6 with the TwinTurbo V8's mesa-flat torque curve (500 pound-feet from 1, 500-5, 750 rpm) and multiplicity of gear ratios (seven-speed dual clutch transmission, the M-DCT) adds an uncanny effortlessness to the experience.
There's yet another catch for Gemstar: TV Guide Interactive was built for a high-speed set-top box, Motorola's DCT 5000, which was promised months ago but held back because of high costs and software integration glitches.
