The Nissan AD is a subcompact van and wagon built by Nissan since 1982. Since 1996, the AD has also been sold as a passenger car under the Nissan Wingroad (Japanese: 日産・ウイングロード, Hepburn: Nissan Wingurōdo) moniker. The range has received an extensive variety of nameplates over the years and in different markets and has also been sold as a Mitsubishi, a Mazda, and a Subaru. In January 2025, Nissan announced that production would end in November of that year, citing slowing sales and a need for corporate restructuring.

In October 1982, the AD Van supplemented (and also gradually replaced) the commercial delivery vans based on Nissan's other vehicles. In 1983, the Nissan Cedric van was discontinued, as was the Nissan Gloria van. It originally came with four front doors and a liftback hatch in back. In July 1983, a two-door version was introduced, meaning that the earlier B310 Sunny Van could finally be retired. The AD range was based on the B11 series Nissan Sunny wagon but has a more square-rigged and utilitarian appearance.

This wagon was sold in Japan as the Sunny AD Van at Nissan Satio Store and as the Pulsar AD Van at Nissan Cherry Store. It was also sold as the "Nissan Datsun AD Van", to tie it together with the Nissan Datsun, which was the name used for the Nissan Pickup in the Japanese Domestic Market.

It came with three engines; the 1.3 and 1.5-litre carburetted E13S and E15S and the 1.7-litre CD17 diesel engine. The transmissions were either a four- or five-speed manual transmission, with the availability of a three-speed automatic for the bigger of the gasoline options. Power outputs for 1984 models in Japan are 75 PS (55 kW), 85 PS (63 kW), and 61 PS (45 kW) respectively.

The rear suspension was designed for commercial usage, so it used a simple leaf spring setup and wasn't intended for ride quality. Low cost, light weight, and a flat, low loading floor were the main consideration. The AD van was designed for very basic duties, and the options list was kept small to enhance economical use and running costs. The AD van used a front wheel drive engine configuration shared with the Sunny. The AD Van was marketed as the Nissan Sunny in some European markets such as Belgium (glazed five-door), beginning with the 1984 model year. In the Netherlands this version was sold as a "Stationwagen" as well as a van, both with the 1.3-liter engine. The United Kingdom received three versions of the three-door Sunny panel van, all with the 1.3-litre E13 engine and 60 hp (45 kW). Payload is 505 kg (1,113 lb).

The AD van remained basically unchanged, except for minor cosmetic changes until the second generation was introduced in 1990 with the Y10 series. The three-door van was also available as a strict two-seater.

Nissan Australia sold the VB11 three-door panel van as part of the Nissan Pulsar range between September 1983 and December 1985, replacing the Sunny (B310) panel van that had been discontinued earlier in 1983. The Pulsar panel van was fitted with the 1.3-liter E13 engine and a four-speed manual transmission. The Pulsar van weighed 840 kg (1,852 lb) and had a payload rating of 540 kg (1,190 lb).

The second-generation AD Van (sold as the Y10/N14 Sunny Wagon in Europe), introduced in October 1990, replaced the Nissan Sunny B13 series wagon, but with a different rear end compared to exported standard Sunny wagons. The vehicle continued as the AD Van, and as a private use (non-commercial) it was marketed as the Nissan Sunny California wagon (N14/Y10). The engines used were the 1.5 L and 1.3 L GA15DS & GA13DS with DOHC and the 1.7 L CD17 diesel continued. The Wingroad/AD Van were also accompanied by a larger retail/commercial station wagon/delivery van called the Avenir/Expert that replaced the Nissan Bluebird U12 wagon/delivery van.
