Steer-by-wire technology comes as option for 2014 Infiniti Q50 sedan

Article by Anita Panait, on February 19, 2013

The 2014 Infiniti Q50 sedan will surely be one of the most interesting vehicles to arrive this summer as the model features a steer-by-wire technology as an option. Infiniti will market the steer-by-wire technology under the trademarked name Infiniti Direct Adaptive Steering on some variants of the Q50, which is bound to replace the outgoing Infiniti G37.

Steer-by-wire controls steering by electronic signals rather than by mechanical links between the steering wheel and the wheels. Other carmakers like BMW and Audi are also pursuing this technology to be used on their vehicles.

The steer-by-wire system – the Infiniti Direct Adaptive Steering – provides two primary benefits.  The system could communicate road conditions into the vehicle's safety system faster as well as allow drivers to choose the feel of steering they want.

Bert Brooks, Infiniti's senior product planning manager for the Q50, said that the Infiniti Direct Adaptive Steering provides a wide range of both steering ratio and effort using the same set of hardware. He added that it allows the vehicle to adapt to all kinds of different driving situations, and it can be tuned by the driver for different settings.

The system offers 96 steering ratios, from which a driver could find one to suit his degree of control for a given stretch of road. Infiniti plans to host its dealer body at a presentation in May in San Antonio to showcase the Infiniti Direct Adaptive Steering as well as other new features of the 2014 Q50, including a display monitor that allows consumers to zoom in or zoom out of images with their fingers.

Each time Infiniti releases new sports sedans, customers are always given a treat due to the excellent presence and exceptional proportions. However, the Q50 brings with it an extra dimension when it comes to the premium style. Looking on the design of the exterior, the typical signature features are still there. There is the crescent-cut C-pillar, dynamic arch, and the “double arch” grille.

While the front section now has a more aggressive look, the Q50 sport model will be offered with a sport fascia on the front. Further, the grille now has a more textural and 3D quality. This is due to the elaborate detailing resulting from the waved mesh pattern surface as well as the chrome surround. The LED headlights are truly unique and when combined with the sharp lines of the marker lights give the impression of that almost human appearance.

In addition, the first impression is generally strong due to the character line, which begins at the “double arch” grille, which is dynamic and smooth at the same time. This character line then flows through the vehicle’s bodyside much like a wave before merging with the rear section. The result is a profile that is intriguing and highly fluid. It also reveals just how sporty and dynamic the stance of the Q50 truly is.

Chief Creative Officer and Senior Vice President Shiro Nakamura shared that the Q50 is clearly inspired by a number of Infiniti concepts dubbed as the “Infiniti Trilogy.” He added that in particular, the main influence is on the Essence and the Q50 continues to honor the previous sports sedans of the brand and the iconic design dynamics. Nakamura continued by saying that while the Q50 has that tightened and sporty look, it manages to complement the wider and lower proportions while resulting in improving the space of the interior.
