Which Triumph TR8 to buy: the only catalogue version, and what its numbers actually buy

The Triumph TR8 in this catalogue is one generation (1980–1981), one body (Roadster), and one named version: 3.5 MT.

Which Triumph TR8 to buy: the only catalogue version, and what its numbers actually buy

The Triumph TR8 in this catalogue is one generation (1980–1981), one body (Roadster), and one named version: 3.5 MT. There is no second engine, no automatic, no restyle, and no later generation to “step up” to — so the buying question is not 3.5 MT versus another TR8, but whether 3.5 MT’s measured figures (132 hp, 253 Nm, 3528 cm³, 8 s to 100 km/h, 90 mm ground clearance, Manual 5, RWD) match what you want from a Roadster of this period. Extra money cannot buy a second TR8 variant here: the database lists `modifikaciy`: 1.

Triumph TR8 versions: what exists to choose from

VersionYearsBodyhpNmcm³FuelCylinders / layoutBoostGearboxDrive
3.5 MT1980–1981Roadster1322533528Gasoline8, V-shapedNoManual, 5RWD

That table is the whole choice set. 3.5 MT is not one of several 3.5-litre TR8s with different horsepower; it is the only row. Distinguishing two same-named versions by power is unnecessary: there is a single 3.5 MT at 132 hp (97 kW).

Engine: what 3.5 MT actually is, in numbers

3.5 MT uses a Gasoline engine of 3528 cm³, 8 cylinders in a V-shaped layout, 2 valves per cylinder, boost: No, fuel system: Carburetor, compression ratio 8.1, bore × stroke 88.9 × 71.1, fuel grade 92.

Specific output from those figures:

Peak torque (253 Nm) is listed at 2500 rpm; peak power (132 hp / 97 kW) at 5000 rpm. The torque peak sits at half the power peak (2500 / 5000 = 0.50). That spread is the arithmetic argument for 3.5 MT if you care about mid-range pull more than a high specific-output figure: 71.7 Nm/L is stronger, relatively, than 37.4 hp/L.

Displacement per cylinder: 3528 ÷ 8 = 441 cm³ per cylinder. Stroke is shorter than bore (71.1 vs 88.9; stroke/bore = 71.1 / 88.9 ≈ 0.80), which is the geometry given — not a second engine option.

Compression 8.1 with Carburetor and fuel 92 is the only fuel/induction package. There is no higher-compression, no boosted (boost: No), and no alternative cylinder count in the data.

Gearbox and drive: no second drivetrain to pay for

3.5 MT is Manual with 5 gears and RWD. There is no Automatic row, no other gear count, and no other drive type. The “extra money” question for transmission does not apply inside this model: you either accept Manual 5 + RWD or you are not choosing a TR8 from this catalogue.

Performance: measured vs not measured

For 3.5 MT:

A buying decision that needs a top speed, an mpg figure, or an emissions band cannot be closed from this data. The one closed performance number is 8 seconds to 100 km/h at 132 hp. Power-to-acceleration pairing is 132 hp for an 8 s run; hp per second of that sprint is 132 / 8 = 16.5 hp per second of 0–100. Without kerb weight (not measured), weight-per-horsepower cannot be calculated — do not invent a kg/hp ratio.

Dimensions, weight, clearance: what you can and cannot compare

The only dimension-class number you can use to accept or reject 3.5 MT is 90 mm ground clearance. Weight-based comparisons (which generation got lighter, which version has better kg/hp) are blocked: both masses are not measured. Tank range estimates are blocked: tank is not measured. Wheel/tyre choice is blocked: kolyosa is not measured.

Brake split is front Disc / rear Drum — one setup, not a choice between two TR8 brake packages.

Generations: what changed (nothing to stack)

1 generation ran 1980-01-01 to 1981-12-31, body Roadster, 1 version. Production window is two calendar years (1980 and 1981). There is no 2nd generation in the data, so there is no “later generation that added power, a sixth gear, or a measured tank.” Restyling is not listed as a separate generation and must not be invented as one.

Year-to-year inside 3.5 MT, start and stop of the version match the generation (1980–1981). You cannot buy an “early” versus “late” TR8 with different hp, Nm, or gearbox from this catalogue: the numbers do not split.

Which version to choose — using only these numbers

Choose 3.5 MT if you want the only Triumph TR8 specification on file: Roadster, Gasoline 3528 cm³, 8 cylinders V-shaped, 2 valves per cylinder, boost No, Carburetor, compression 8.1, 132 hp at 5000 rpm, 253 Nm at 2500 rpm, Manual 5, RWD, 8 s to 100 km/h, 90 mm clearance, front Independent spring, front Disc, rear Drum, fuel 92.

Do not expect a second TR8 SKU for more power, more torque, an automatic, AWD, a measured mpg, a measured top speed, or a measured kerb weight. Arithmetic between versions is empty: 132 − 132 = 0 hp, 253 − 253 = 0 Nm, 3528 − 3528 = 0 cm³. The “what extra money buys” answer is no extra catalogue version.

Reject 3.5 MT on data grounds if you require:

Reliability and problems (what this file does and does not say)

This dataset has no reliability scores, no failure rates, and no problem lists. Do not treat silence as “no problems.” What you can pin to 3.5 MT is hardware type: Carburetor, Gasoline, 8 cylinders V-shaped, 2 valves per cylinder, boost No, Manual 5, RWD, rear Drum, front Disc. Those are specification labels, not durability claims.

Specs recap for 3.5 MT (self-contained)

Triumph TR8 3.5 MT (1 generation, 1980–1981, Roadster): 132 hp (97 kW) at 5000 rpm, 253 Nm at 2500 rpm, 3528 cm³, Gasoline, 8 cylinders V-shaped, 2 valves per cylinder, boost No, Carburetor, compression 8.1, bore × stroke 88.9 × 71.1, fuel 92, 0–100 in 8 s, top speed not measured, Manual 5, RWD, consumption not measured, tank not measured, CO2 not measured, eco class not measured, kerb weight not measured, gross weight not measured, clearance 90 mm, wheels not measured, front suspension Independent, spring, rear suspension not measured, front brakes Disc, rear brakes Drum.

Bottom line: there is one buyable specification name — 3.5 MT — at 37.4 hp/L and 71.7 Nm/L, with the only closed dynamic figure an 8-second 0–100 and the only closed dimensional figure 90 mm of clearance. If those measured values are enough, 3.5 MT is the TR8. If you need a second column of numbers, this model’s catalogue does not supply one.
