Reading the fuel economy numbers. The EPA does not rate cutaway shuttle buses, so there is no window sticker. These come from the FTA’s Altoona test, which measures fuel use on three federal duty cycles on the same dynamometer for every builder. Manhattan is dense stop-and-go at low average speed — the hardest work a shuttle does. Orange County Bus Cycle is a mixed suburban route with regular stops, closest to how most shuttles actually run. HD-UDDS is urban plus sustained highway, what an airport run or a longer charter looks like. Numbers are comparable between builders only when both buses were tested under the current protocol, in place since 2016.
Specifications vary by chassis and configuration. Typical build time 90–120 days from order · 2026 average: 92 days.
