Dodge
Viper 1:28 Edition ACR (2017)

Why it matters

The 1:28 Edition ACR was one of the 25th-anniversary special editions for the final Viper model year. It commemorates the 1:28.65 production-car lap record set by a Viper ACR at Laguna Seca in October 2015, and was the smallest-run edition at 28 units.

How rare is it?

Six separate kinds of rarity – never combined into one number.

Each kind of rarity is rated separately and never combined.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Dodge announced the five 25th-anniversary limited editions on 21 June 2016 and opened orders on 24 June. All 28 units of the 1:28 Edition sold out within 40 minutes, the fastest of the series.

The edition follows the same record-tribute idea as the 33-unit 2010 Viper ACR 1:33 Edition, built to mark a 1:33.915 Laguna Seca lap from November 2009.
