BMC Tuğra

The Tuğra is the heavy truck range of the Turkish maker BMC. BMC’s own site, bmc.com.tr, routes its truck menu to bmctugra.com, which presents the Tuğra in three series: a road series of rigids (the TGR 1832 at 4x2, the TGR 2532 at 6x2 and the TGR 3232 at 8x2), a tractor (the TGR 1846, 4x2) and a construction series (the TGR 3540 at 6x4 and the TGR 4340 at 8x4). This page is built from the data sheets BMC links from those model pages, one per sub-variant, read on 16 October 2026: their PDFs were generated on 30 January 2025 and each carries BMC’s own revision note dated April 2024. The wheel-formula notation is set out in axle configurations explained.

Range and cab

The cab varies by model. The 1832 and 2532 sheets list a low-roof cab without a bed (BMC’s “Alçak Tavan, Yataksız Kabin”), with mechanical cab suspension as standard and four-point independent air cab suspension as an option. The 3232 sheets give a standard-roof one-berth sleeper cab on air suspension, and the 1846 sheets a high-roof two-berth sleeper cab, also on air suspension. BMC’s 2532 and 3232 model pages are both headed “Yataklı Kabin” (sleeper cab), but the 2532 data sheets themselves state “Yataksız Kabin” (cab without a bed). What the cab roof heights and berth counts mean is set out in truck cabs explained. A sibling model from the same maker, the city bus, has its own page: BMC Procity+ Electric. No BMC document opened for this page gives a production-start year for the Tuğra.

Engines

BMC fits three engine families across the range, each named on the sheets as a Euro 6 unit and each limited to 90 km/h.

The road rigids run a Cummins ISB6.7, a 6.7-litre six-cylinder turbo-intercooler diesel with a bore and stroke of 107 mm and 124 mm, at 320 PS and 1,200 Nm at 1,100 rpm. BMC’s sheets give the same 320 PS rating two ways: as 233 kW on the 1832 sheets and as 239 kW on the 2532 and 3232 sheets. The construction trucks run a Cummins L9 of 8.9 litres and six cylinders at 400 PS (298 kW) at 2,100 rpm and 1,700 Nm at 1,400 rpm; the engine is named “Cummins ISL9E6E” on the 3540 DXD sheet and “Cummins L9E6E” on the 3540 TXT and 4340 DXD sheets. The TGR 1846 tractor runs an FPT Cursor 11 ENT VI, an 11.1-litre six-cylinder turbo-intercooler diesel with a bore and stroke of 125 mm and 140 mm, at 460 PS (338 kW) at 1,900 rpm and 2,150 Nm; the ELG sheets place the torque peak at 925 rpm and the ESS sheets at 1,050 to 1,550 rpm. How a power rating relates to its rated speed is set out in reading truck power figures.

Transmission

The road rigids use a ZF manual gearbox: the 1832 sheet gives a ZF 9 S with nine forward gears and one reverse, ratios of 12.73:1 and 1.00:1 (reverse 12.04:1) and a single-disc clutch of 430 mm (17 inches), and the 3232 sheets give a ZF 9 S 1310 TD. The construction and tractor models use the ZF 12 TX automated gearbox with twelve forward gears and two reverse, optional with an Intarder: the construction sheets give a ZF 12 TX 1815 TO as standard and a ZF 12 TX 1811 TO (with Intarder) as an option, and the 1846 sheets give a ZF 12 TX 2210 TO with a ZF 12 TX 2211 TO option. The 1846 sheets label the same 2210 TO gearbox two ways, “Otomatik” (automatic) on the ELG sheet and “Robotize” (automated) on the ESS sheet; the 1846 ratios run from 12.9 to 0.7 (reverse 13.10:1 and 10.12:1). How these automated gearboxes work is set out in automated manual transmissions.

Axles, suspension and brakes

The road rigids and the 1846 tractor carry a single-speed driven rear axle rated 13,000 kg; the front steer axle is rated 7,500 kg on the 4x2 and 6x2 rigids and the 1846, and 7,000 kg on the 8x2, which also carries a self-steering axle rated 7,100 kg. The 1832 sheet gives the rear axle ratio as 4.63:1 and the 1846 sheet as 3.08:1. The construction 6x4 (3540) carries a front axle rated 8,000 kg and a driven rear tandem rated 13,400 kg per axle at a 5.41:1 ratio; the 8x4 (4340) carries two front axles rated 9,000 kg each and a rear tandem rated 16,000 kg per axle. The 1832 sheet describes the front suspension as semi-elliptic leaf springs with telescopic dampers and the rear as auxiliary-reinforced semi-elliptic leaf springs with telescopic dampers, with an anti-roll bar on both axles.

For braking, the sheets give a dual-circuit full-air system. The 1832, 2532 and 1846 sheets list it with EBS, ESC, LDWS and AEBS; the 3232 and the construction sheets list ABS and ASR instead. The 1832 S and the construction trucks have 410 × 200 mm Z-cam drum brakes, while the 3232 and the 1846 have 430 × 45 mm disc brakes. Auxiliary braking is an engine brake: a plain engine brake on the road rigids, rated at 252 kW on the construction trucks and 372 kW on the 1846, with a 600 kW Intarder as an option on the construction and tractor models. How these systems work is set out in retarders and engine braking explained.

Dimensions and weights

BMC publishes dimensions and weights on each variant’s own sheet. The figures below are overall length and height excluding mirrors, the wheelbase, and the kerb weight, which every sheet states without a driver and with 20 L of fuel, 5 L of AdBlue and minimum equipment. Widths are 2,545 mm on the road and tractor sheets and 2,550 mm on the construction sheets. Heights on the 3540 and 4340 are quoted on 315/80 R22.5 tyres, and the “with spoiler” heights are the sheets’ second figure for a cab with a roof spoiler.

The permissible gross weight BMC states on each sheet’s “İzin Verilen Toplam Ağırlık” row is 18,000 kg on the 1832 and the TGR 1846, 32,000 kg on the 3232, 34,800 kg technical and 26,000 kg legal on the 3540, and 42,800 kg technical and 32,000 kg legal on the 4340. The 1846 tractor sheets give optional fifth-wheel heights of 1,050, 1,100, 1,150 and 1,200 mm but no gross combination weight. The distinction between a technical rating and a legal plated weight is set out in truck weights and gross combination weight.

Fuel, AdBlue and electrical system

The AdBlue tank is 74 L on the road and construction sheets. The fuel tank is 300 L on the 1832, the 2532 WBD and the construction sheets, 405 L on the 3232 BL and 500 L on the 2532 WBL and the 3232 BXL; the 1832 L lists a 300 L aluminium tank and the 2532 WBL a 500 L aluminium tank as options. The 1846 tractor sheets give a 600 L fuel tank and an 80 L AdBlue tank, with an additional 300 L aluminium tank among the options and, on the ESS sheet, a 600 L steel tank. The electrical system is 24 V, with two 12 V batteries of 180 Ah, a 120 A alternator and a 24 V starter on the 1832 S; the 1846 ESS sheet lists 225 Ah and 190 Ah batteries among the options.

Tyres and chassis

The 1832 S runs 315/80 R 22.5 tyres, six plus a spare, on 9 × 22.5 rims; the 3540 runs the same size ten plus a spare, with 13 R22.5 as an option, and the 4340 twelve plus a spare. The 1846 tractor runs 295/80 R 22.5 and 315/70 R 22.5, six plus a spare; the ESS sheet makes the 295/80 standard and the 315/70 optional on 8.25 × 22.5 rims, while the ELG sheet reverses this on 9 × 22.5 rims. The chassis is a steel frame of 8 mm, with a 5 mm reinforcement on most road and construction sheets, and a single-piece high-strength C-section of 8 mm on the 1846.

Safety and driver-assistance systems

The 1832, 2532 and 1846 sheets list EBS, ESC, a lane-departure warning system (LDWS), an advanced emergency braking system (AEBS) and a hill-hold assist as standard; the 3232 and the construction sheets list an anti-lock braking system (ABS) and traction control (ASR) in their place. Every sheet carries an immobiliser, a differential lock, a remote central lock, a digital tachograph and a driver seatbelt sensor as standard. Among the listed options are a tyre-pressure warning sensor, a fleet-management (FMS) socket and module and, on the 1846, an ADR package.

Equipment and options

Standard equipment on the 1832 S includes air conditioning, a radio with MP3 and Bluetooth, USB sockets in the driver and passenger areas, a four-point mechanical cab suspension, a cruise control, heated electric side mirrors, electric windows and front fog lights. Listed options include a 7-inch multimedia screen, a four-point independent air cab suspension, a heated driver’s seat, a heated windscreen, a smart tachograph, an electric cab tilt and a drawbar-type towing hook. The 2532, 3232 BL and 1846 ESS sheets list an automatic digital climate control of 6 kW in place of the plain air conditioning, and the 1846 sheets add a 55 L refrigerator and a catwalk walking plate.

Source notes

The Tuğra is BMC’s heavy truck range, sold as road rigids (TGR 1832 4x2, TGR 2532 6x2, TGR 3232 8x2), a tractor (TGR 1846 4x2) and construction trucks (TGR 3540 6x4, TGR 4340 8x4). The road rigids run a Cummins ISB6.7 of 6.7 litres and six cylinders at 320 PS and 1,200 Nm; BMC’s sheets give the 320 PS as 233 kW on the 1832 sheets and 239 kW on the 2532 and 3232 sheets. The construction trucks run a Cummins L9 of 8.9 litres at 400 PS (298 kW) and 1,700 Nm, named ISL9E6E on the 3540 DXD sheet and L9E6E on the 3540 TXT and 4340 DXD sheets. The 1846 tractor runs an FPT Cursor 11 of 11.1 litres at 460 PS (338 kW) and 2,150 Nm, which the ELG sheets place at 925 rpm and the ESS sheets at 1,050-1,550 rpm. All engines are Euro 6 and limited to 90 km/h. The road rigids use a ZF 9-speed manual and the construction and tractor models the ZF 12 TX automated 12-speed, optional with an Intarder. The permissible gross weight is 18,000 kg on the 1832 and the TGR 1846, 32,000 kg on the 3232, 34,800 kg technical and 26,000 kg legal on the 3540, and 42,800 kg technical and 32,000 kg legal on the 4340. No BMC document opened gives a production-start year, and no sheet gives a gross combination weight for the tractor.
