The Subaru VIZIV is a series of diesel-electric hybrid concept sports SUVs designed and built by Subaru, the first of which was unveiled at the 2013 Geneva Motor Show. The VIZIV series included several signature Subaru design features, such as the use of horizontally-opposed engines and all-wheel drive, and built on prior Subaru hybrid concepts such as the B9SC, B5-TPH, and Hybrid Tourer by using a three-motor layout.

Design

The name "VIZIV" was derived from the phrase "Vision for Innovation" and was meant to illustrate the Subaru concept of "enjoyment and peace of mind." The VIZIV concept was also meant to suggest the brand's future styling direction,[1] and the hexagonal grille was reused in November 2013 for the Legacy Concept revealed at the Los Angeles Auto Show.[2]

VIZIV (2013)

The VIZIV CONCEPT had its world premiere at the Geneva Motor Show in March 2013.[1] The 2013 VIZIV features a hexagonal grille standing proud of the body (and echoed in the rear panel) intended to serve as a future Subaru design feature.[3]

The use of electric motors for the rear wheels eliminates the need for a mechanical power shaft from the front-mounted engine, allowing the interior floor to be lower and flatter.[3]

VIZIV Evolution (2013)

The VIZIV EVOLUTION debuted at the Tokyo Motor Show in October 2013 with the same layout and external dimensions as the 2013 Geneva VIZIV, but with a smaller (1.6-litre) direct injection turbodiesel (DIT).[4]

One year later, the VIZIV 2 debuted at Geneva in March 2014, featuring the smaller 1.6-litre direct-injection turbodiesel from the VIZIV EVOLUTION in a slightly larger body with four doors. The shape of the headlamps was intended to evoke the horizontally-opposed engine.[5]

VIZIV Future Concept (2015)

The VIZIV FUTURE CONCEPT had its world premiere at the Tokyo Motor Show in October 2015.[6] It dropped the independent rear motors in favor of a single rear motor.[7]

VIZIV-7 (2016)

A VIZIV-7 midsize SUV concept was revealed at the 2016 Los Angeles Auto Show, using styling cues but not the hybrid powertrain from prior VIZIV concepts. The VIZIV-7 is a three-row vehicle intended to show the size and styling of a future Tribeca replacement for the North American market, to debut in 2018.[8] An updated, smaller Subaru Ascent Concept was unveiled at the 2017 New York Auto Show, where Subaru confirmed plans to sell the Ascent by 2018.[9]

Technical

The 2013 VIZIV featured what Subaru called an "independent-rear-motor-driven symmetrical AWD" system, where a 2.0-litre diesel horizontally-opposed ("Boxer") engine drove the front wheels through the continuously variable transmission (CVT, which Subaru branded "Lineartronic") and provided power generation, and each rear wheel was powered by an independent electric motor. The front wheels could also be powered by a single electric motor.[3] At low speeds and in city traffic, the vehicle is moved solely by the three motors under electric power, taking advantage of low-speed electric motor torque to provide good acceleration with low fuel consumption.[3] At highway speeds, the diesel engine and CVT are used.[3] The use of two rear electric motors allows the car to allocate torque from front to rear and laterally (to the outside wheel) when the steering wheel is turned, enhancing the car's handling.[3]

The 2013 VIZIV is equipped with a driving assist system, which Subaru branded "EyeSight".[3] EyeSight uses twin CCD cameras focused on a single point in front of the car to detect road conditions and objects in front of the car, enabling pedestrian detection, automatic brake engagement, and adaptive cruise control.[10]

A sports version of the 2014 VIZIV 2 concept, called the VIZIV GT Vision Gran Turismo, was designed for the videogame Gran Turismo 6.[11][12] The car features a large diffuser and roof-integrated spoiler, and was made available within the game in November 2014. According to the game's statistics, the VIZIV GT Vision Gran Turismo has a curb weight of 1,380 kg (3,042 lb) with a maximum output of 591 hp (441 kW) and 593 ft·lb (804 N·m).[13]
