305xx

305xx is a designation employed by the automotive industry to identify a family of mid‑size passenger vehicles that were produced by the manufacturer AutoTech Corporation between 1998 and 2005. The name originated from the 305 chassis platform, and the “xx” suffix is used to differentiate the specific body or trim variants within the platform. Models under the 305xx banner typically included sedan, wagon, and upscale coupe variants, all built around a shared set of powertrains and suspension components.

The 305xx series was noted for its blend of design and engineering innovations that marked a transition period for AutoTech. In 1999 the line introduced a front‑wheel drive layout with independent suspension that improved handling and fuel efficiency relative to the earlier 300xx models. Engine options ranged from a 2.0‑liter inline‑four producing 145 horsepower to a 3.0‑liter V6 delivering up to 215 horsepower, all paired with either a five‑speed manual or a four‑speed automatic gearbox. Standard equipment typically included power steering, central locking, and an optional air conditioning system, while higher‑trim variants offered additional features such as leather upholstery, alloy wheels, and upgraded sound systems.

The 305xx lineup helped AutoTech to maintain market relevance during a period of intense competition and set the stage for the later 400xx series that adopted front‑engine and front‑wheel drive configurations on a revisited architecture. Production of the 305xx models ceased in 2005 as AutoTech shifted focus to hybrid and emerging vehicle platforms, but the series remains a reference point for collectors and automotive historians studying late‑20th‑century mid‑size sedan development.
