Infiniti Gives Signature Editions to 2017 Q50 3.0t Sports Sedan and 2017 QX80 SUV

Both special editions combine subtle design tweaks with improved equipment

Infiniti is expanding the availability of its Signature Edition trim for its 2017 Q50 3.0t sports sedan at the Chicago Auto Show, in addition to the return of the same edition for the 2017 QX80 SUV.

The Infiniti Q50 3.0t Signature Edition stands out from lesser grades thanks to design upgrades including bright-finish alloy wheels with all-season run-flat tires, LED headlights, and LED rear brake lights.

The list of standard features is long and includes a power-sliding tinted glass moonroof, Infiniti's InTouch Navigation with 3D building graphics, voice recognition, and Navi Synchronized Adaptive Shift Control, as well as SiriusXM Traffic and Infiniti InTouch Services including six months of safety, security and convenience services. A 60/40 split-fold rear seat is also standard.

Power (300 hp to be exact) comes from the VR-series 3.0-liter V6 twin-turbo engine, available with either rear-wheel drive or all-wheel drive. The Q50 will arrive in showrooms this month, with prices starting from $38,700 for the RWD version and $40,700 for the AWD model.

As for the QX80 Signature Edition, it returns for a second year with a generous equipment such as a Saddle Tan leather interior, chrome mirror caps, clear stop light, and dark-finish 22-inch forged aluminum-alloy wheels with 275/50R22 all-season performance tires.

It also comes with a host of driver assistance technologies such as Intelligent Cruise Control (Full-Speed Range), Distance Control Assist, Forward Emergency Braking with Pedestrian Detection, Predictive Forward Collision Warning, Backup Collision Intervention, Lane Departure Warning and more.

The QX80 Signature Edition can be had either as a seven- or eight-passenger vehicle and is offered in 2WD and 4WD versions. There is only a single engine option, a 400 hp 5.6-liter V8.

The special edition SUV will arrive in dealerships in May, with prices to be announced closer to the on-sale date.
