Part of the SL's update keeps its design language in sync with other Mercedes-Benz models, such as using new headlight casings that reach up high into the fenders. The grille also gets a simplified look, with a single bar, while vents on the front fenders evoke World War II fighter planes.

Mercedes-Benz gives the SL its AMG treatment, which means a big 6.3-liter hand-built V-8 engine. The car uses a new seven-speed multiclutch transmission that shifts like a manual but doesn't require the driver to push a clutch pedal. The transmission shifts faster than a standard manual and also can offer a fully automatic mode.

A step down from the SL, the SLK also gets a redesign. Most importantly from the Car Tech angle, Mercedes-Benz points out that it gets the latest head unit, which we assume is the hard drive-based system we saw in the C300.

The updated CLS demonstrates Mercedes-Benz's grille simplification plan, going from four bars to two. Being a trendsetter, it gets trapezoidal tailpipes and new signal lights in the form of arrow-shaped arrays in the tail and on the mirrors.
