Mercedes-Benz / Tremonia Sprinter City 45
The Sprinter City 45 is a compact low-entry bus designed for scheduled services where a conventional single-decker would be unnecessarily large. Its narrow 2.02-metre body makes it particularly suitable for historic town centres, rural routes and densely populated residential areas. A low-floor section provides accessible accommodation for wheelchairs and pushchairs, while the raised rear seating area maximises interior space. Depending on its approval and seating arrangement, the City 45 can accommodate up to 28 passengers, including standing passengers, making it considerably more versatile than a conventional minibus.

Mercedes-Benz / Tremonia Sprinter City 75

Its distinctive body incorporates a generous low-floor area, accessible passenger entrances and a specialised heavy-duty rear axle.

Tremonia City 45 Electric
The City 45 Electric brings zero-emission operation to Tremonia's compact low-entry city bus platform. Retaining the narrow body and accessible passenger area of the diesel Sprinter City 45, it uses a substantial 126kWh battery system and an electric drivetrain designed for repeated urban operation. Tremonia quotes up to approximately 187 miles under favourable SORT test conditions, although actual range will depend heavily on route, passenger load and weather. With space for up to 22 passengers, the City 45 Electric is particularly suited to smaller public transport routes, community services and town-centre operations where electric running is increasingly desirable.

Important Information
Prices, specifications, dimensions, seating capacities, weights, power outputs and equipment are based primarily on information published by vehicle manufacturers, their official representatives and established specialist converters. Specifications can vary by trim, body length, configuration, conversion, model year and individual vehicle. Tremonia Mobility is an independent manufacturer producing specialist buses using Mercedes-Benz vehicle platforms and mechanical components.
Prices shown are UK prices where available and are intended as a guide. Where an official UK list price is unavailable, pricing may be shown as approximate or POA. Prices can change and may exclude optional equipment, conversions, delivery charges or other operator-specific costs. International model availability does not guarantee confirmed UK supply.
Passenger capacities on low-entry City models may include standing passengers. The maximum passenger capacity must not be confused with the number of available seats. Seating arrangements, standing allowances and wheelchair accommodation vary according to specification and vehicle approval.
Licence categories shown are a general guide only. Individual driving entitlement can vary according to passenger-seat count, vehicle weight, vehicle length, licence issue date, grandfather rights, Section 19 operation and other exemptions. Passenger-seat counts used for licence purposes exclude the driver. Always check the vehicle's plated specification and your own driving-licence entitlement before driving.
Electric driving ranges are manufacturer claims based on stated test conditions, including SORT bus-duty testing where specified, and should not be treated as directly comparable with passenger-car WLTP figures. Real-world range will depend on passenger load, speed, temperature, heating, route characteristics and operating conditions.
Specifications are checked against the latest information reasonably available to The New Yardstick at the time of publication or update. Manufacturers and converters may alter specifications, pricing or model availability without notice.
