The Optare Sigma was a step-entrance single-deck bus body manufactured by Optare between 1994 and 1996 on the Dennis Lance chassis. The body was constructed from Alusuisse aluminium alloy with fiberglass front and rear panels.[1][2] It was the single-deck version of the Optare Spectra.[3]
The Sigma was not a low-floor bus although its floor height of 40cm is considered low for a step-entrance design. The first built had two doors, the remainder only one.[2] It was also similar in design to the Optare Delta.[4] The Vecta had the same body styling as the Sigma but was designed for medium-length chassis, the Sigma was for full length chassis.[5][6]
Only 54 were produced, primarily being purchased by Brighton & Hove (20), Trent Barton (17) and Gateshead & District (14).[6][2][7]
Unlike the Spectra, it did not last long enough to be developed into a true low-floor bus and was replaced by the Optare Excel in 1995.[5]
