Which version to buy: 4.0 V12 MT
There is no second T.50 to compare on power, torque, weight, or drive. Arithmetic on this one row is what the numbers allow.
4.0 V12 MT is the only row in the data. It is a Gasoline 12-cylinder V-shaped engine of 3994 cc, Central layout, No boost, Direct injection (direct), Manual 6, RWD. Output is 650 hp (478 kW) and 450 Nm. Kerb weight is 980 kg. Ground clearance is 120 mm. Production of this version starts 2021-02-01 and has no stop date in the data.
There is no second T.50 to compare on power, torque, weight, or drive. Arithmetic on this one row is what the numbers allow.
Engine: what 650 hp and 3994 cc buy per litre
Power per litre for 4.0 V12 MT: 650 hp / 3.994 L = 162.7 hp/L. In kilowatts: 478 kW / 3.994 L = 119.7 kW/L.
Torque per litre: 450 Nm / 3.994 L = 112.7 Nm/L.
Bore and stroke are 81.5 x 63.8. Stroke/bore is 63.8 / 81.5 = 0.783, so the 12-cylinder unit is oversquare on the figures given. Valves: 12 cylinders × 4 valves per cylinder = 48 valves. Boost is No, so the 162.7 hp/L is not coming from a turbo or supercharger in this data.
Fuel is 95. Compression ratio is not measured. Power rpm and torque rpm are not measured, so you cannot place the 650 hp or 450 Nm on a rev scale from this catalogue.
If you wanted more cylinders, a different layout, boost, or another fuel type, the T.50 data does not offer them. The only engine on the page is this Gasoline V-shaped 12.
Specs: gearbox, drive, and what a second version would have changed
4.0 V12 MT is Manual with 6 gears and RWD. There is no automatic, no extra gear count, and no AWD or FWD alternative in the data.
A hypothetical second version with the same 650 hp but another gearbox would still be a different catalogue row. That row is not here. Buying “the T.50 with a different transmission” is not a choice this dataset supports.
Layout is Central. Front/rear suspension is Independent, spring on both axles. Front brakes: Ventilated disc. Rear brakes: Disc ventilated (label as in the data). None of those items vary by version, because there is only 4.0 V12 MT.
Weight per horsepower: 980 kg vs 650 hp
Kerb weight 980 kg and 650 hp give 980 / 650 = 1.51 kg per hp, or 650 / 980 = 0.663 hp per kg.
Torque vs mass: 980 / 450 = 2.18 kg per Nm.
Gross weight is not measured, so payload and the gap between kerb and maximum mass cannot be calculated. You cannot say how much extra mass the structure is rated for.
If a heavier sister version existed at the same 650 hp, kg per hp would rise in lockstep with kerb weight. No such sister is listed. The mass figure you are buying is 980 kg, period.
Performance and mpg: what is not measured
4.0 V12 MT acceleration 0–100 is not measured. Top speed is not measured. City, highway, and combined consumption are not measured. CO2 is not measured. Eco class is not measured. Tank size is not measured.
You cannot rank this Coupe against another T.50 on sprint, vmax, or mpg, because there is no second version and these fields are empty. “Better economy” or “faster to 100” is not a comparison this catalogue can make. Treat those as not measured, not as absent from the car in principle.
Dimensions: clearance, tank, wheels
Ground clearance for 4.0 V12 MT is 120 mm. Wheel sizes are not measured. Tank is not measured. Body type is Coupe only; there is no second body in generation 1.
120 mm is the only ride-height number. There is no high-clearance or lowered variant to pick. If 120 mm is too low for the roads you use, the data does not offer another T.50.
Generations: what generation 1 did not change
1 generation only (7251 in the source keys). Years: from 2021-02-01, stop not measured (null). Body: Coupe. Versions in this generation: 1.
There is no generation 2, so there is no “later chassis,” no restyle inside the generation, and no arithmetic of “gen 2 added X hp.” Everything that can be said about change over time is: this generation started 2021-02-01 and is still without an end date in the data.
Problems and reliability: what the numbers do and do not cover
The data does not list faults, recalls, or reliability scores. Those topics cannot be filled from this source.
What the numbers do fix: a No-boost Gasoline 12 with Direct injection (direct), Manual 6, RWD, kerb 980 kg, 650 hp, 450 Nm. Service complexity, parts, and how the car behaves at rpm are not measured here.
Which version to choose — the comparison that exists
There is one version. The choice is 4.0 V12 MT or nothing in this model line.
On the arithmetic that is allowed:
| Version | hp | Nm | cc | Fuel | Cylinders | Layout | Boost | Gearbox | Drive | kg/hp | hp/L |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 4.0 V12 MT | 650 | 450 | 3994 | Gasoline | 12 | V-shaped | No | Manual 6 | RWD | 1.51 | 162.7 |
4.0 V12 MT is the high specific-output, low-mass row: 162.7 hp/L and 1.51 kg/hp, No boost, Central 12, Manual 6, RWD, Coupe, 980 kg, 120 mm clearance.
You are not paying extra inside the T.50 range for more gears, more driven wheels, or a second engine, because those options are not in the data. Extra money versus another Gordon Murray model is also not measured here; this article has no prices.
If the requirement is a Gasoline naturally aspirated (No boost) V-shaped 12, Manual, RWD, around 650 hp and under 1000 kg kerb, 4.0 V12 MT is the only T.50 that matches, because it is the only T.50 listed. If you need measured 0–100, top speed, mpg, tank, wheels, or gross weight before you buy, those fields are not measured for this version, and no other version supplies them.
