BlueHybrid likely will cost about the same as today's S550. The
problem is, to the aver age shopper, it looks like the three-year-old S350. You can look
for aerodynamic amendments or changes in ride height, but you'll be
looking in vain. Only subtle BlueHybrid badges on the flanks and
the trunk lid signal the high-tech driveline. Keener observers will
spot new wheels and tires: 18-inch alloys with
low-rolling-resistance Continental Contact 235/55R rubber.
Underneath, a lightly reworked version of the existing Mercedes
3.5-liter V6 gasoline engine gains a new cylinder head, lightweight
pistons and a reprofiled camshaft for altered valve timing. It does
without the direct injection used on the CLS350's similar V6.
