Hans-Peter Wunderlich, Creative Director Interior Design at Mercedes-Benz, puts it quite simply: “Steering-wheel design is a world of its own and a very special challenge that is often underestimated.”
The new Mercedes E-Class models are available with two steering wheel designs. There is the “Luxury” version, which has its control surfaces on what are meant to resemble flower leaves. There is the “Supersport,” which has a set of double-deck spokes that are said to be “reminiscent” of the wheel wing nuts on a sports car.

But what makes these steering wheels significant is that they feature smartphone-like capacitive capability. There are two sensor mats, located on the front and back sides of the steering wheel rim. When the wheel is gripped, assuming that there is a sufficient amount of force, there is a change in capacitance which is converted into a digital signal by a control unit. Consequently, it is determined whether the driver is using the steering wheel. Should the system determine that when the car is in semi-automated driving mode and the steering wheel has not been engaged by the driver for a set period of time, there is a warning given to the driver. If that doesn’t result in the wheel being taken, then the system activates Emergency Stop Assist. In addition to which, on the aforementioned control surfaces the “buttons” used to control various functions are also based on capacitive sensors so that taps and swipes familiar to smartphone users are used to make selections.
But how did the steering wheel develop? Here’s a walk-through key moments in Mercedes history:
1886
The Benz Patent-Motorwagen. No wheel. A lever.
1894
A Panhard & Levassor (powered by a Daimler engine) is the first car with a steering wheel. It was invented by French engineer Alfred Vacheron.
1902
Mercedes Simplex. Steering column is tilted for better ergonomics. Levers added for things like adjusting ignition timing and the air/fuel mixture.
1954
Mercedes 220 S Ponton. Note that by this time there is a horn ring. The gearshift was placed on the steering column.
1971
Mercedes 350 SL features the four-spoke safety steering wheel that features a padded plate to absorb impacts. The horn rim is eliminated.
1998
The S-Class 220 features a multifunctional steering wheel that was integrated with the COMAND (Cockpit Management and Data) system. The driver could control functions via thumb activation.

Mustang Changes for 2018
On Tuesday Ford unveiled—using the social media channels of actor Dwayne Johnson (this has got to unnerve some of the auto buff book editors)—the 2018 Mustang, which has undergone some modifications: under the hood (the 3.7-liter V6 is giving way to a 2.3-liter EcoBoost four, and a 10-speed automatic is available), on the dash (a 12-inch, all-digital LCD screen is available for the dashboard), at the tires (12 wheel choices), on the chassis (MagneRide damper technology is being offered with the Mustang Performance Package), and on the exterior (three new paint colors). And while on the subject of the exterior, there are some notable changes—a lower, remodeled hood, repositioned hood vents, new upper and lower front grilles, LED front lights, revised LED taillamps, new rear bumper and fascia.

2018 Genesis G80 AWD 3.3T Sport
The thing about the 2018 Genesis G80 AWD 3.3T Sport: The head of a valet service at a restaurant on New Year’s Eve said to me as his associate handed me back the key fob (a hefty object, speaking to the fact that this is a substantial vehicle), “We don’t see many of these.” A couple days later, a locksmith in downtown Plymouth, who was making some keys for autofieldblog HQ (yes, there are still independent locksmiths that make keys for doors) looked out his window and said to me, “What’s that?” Neither of these probably make the people at Genesis all that happy, but in both cases the tone of voice indicated admiration, if not full-on interest.
