Vector W8 Twin Turbo: which version to buy and why
There is only one Vector W8 Twin Turbo to choose. The catalogue lists 1 generation (1989-01-01 to 1994-12-31), Coupe body, and 1 version: 6.0 AT. There is no second engine, no restyling row, and no rival trim inside the same model line.
There is only one Vector W8 Twin Turbo to choose. The catalogue lists 1 generation (1989-01-01 to 1994-12-31), Coupe body, and 1 version: 6.0 AT. There is no second engine, no restyling row, and no rival trim inside the same model line. The buying question is not “which W8 Twin Turbo” but whether 6.0 AT’s measured numbers — 634 hp, 854 Nm, 5973 cm³, 4.3 s to 100 km/h, 350 km/h, 1620 kg kerb, 106 L tank, 140 mm clearance — match what you want from a rear-drive Automatic Coupe. Every figure below is from that single row; where the row is empty, the value is not measured.
Specs that decide the only version
6.0 AT is Gasoline, 8 cylinders, V-shaped, 2 valves per cylinder, Turbo, Distributed injection (multi-point), compression 8, bore × stroke 101.6 × 92.1, fuel 95. Gearbox: Automatic, 3 gears. Drive: RWD. Engine location: not measured.
Power is 634 hp / 466 kW at 5700 rpm. Torque is 854 Nm at 4900 rpm. Displacement 5973 cm³ is 5.973 litres, so specific output is 634 ÷ 5.973 ≈ 106.1 hp per litre and 466 ÷ 5.973 ≈ 78.0 kW per litre. Torque density is 854 ÷ 5.973 ≈ 143.0 Nm per litre.
Those ratios are the whole “which engine” comparison: there is no milder 6.0 AT and no hotter one. If two rows shared the name 6.0 AT, they would be split by horsepower; here there is a single 634 hp 6.0 AT.
Engine and drivetrain: what the extra output is for
Peak power at 5700 rpm and peak torque at 4900 rpm sit 800 rpm apart. The 3-speed Automatic has no extra ratios to fill that gap, so the Turbo Gasoline 8 with V-shaped layout is doing the work that a taller gearbox would otherwise do. Compression 8 is the number on the card; it is not a second tune.
RWD is the only drive. There is no AWD 6.0 AT to buy for weather, and no extra hp tax for all-wheel hardware — because that hardware is not in the data.
Front brakes Disc, rear Drum. Front suspension Independent, spring; rear Dependent, spring. Wheel size: not measured. Those are not options on a second version; they are the chassis of 6.0 AT.
Performance and economy (mpg is not measured)
6.0 AT is listed at 4.3 s 0–100 km/h and 350 km/h. City, highway, and combined consumption: not measured. CO2: not measured. Eco class: not measured. Fuel is 95; tank 106 L. Range in kilometres cannot be calculated without a consumption figure, so mpg and range stay not measured rather than guessed.
With only one version, you cannot buy a slower W8 Twin Turbo to save fuel: there is no second economy number. The performance choice is binary: take 4.3 s / 350 km/h, or do not take the model.
Power-to-weight on kerb mass: 1620 ÷ 634 ≈ 2.56 kg per hp, or 634 ÷ 1620 ≈ 0.391 hp per kg (391 hp per tonne). Per kW: 1620 ÷ 466 ≈ 3.48 kg/kW. Gross vehicle weight: not measured, so loaded power-to-weight is not measured.
Dimensions, weight, and what they buy
Kerb weight 1620 kg. Gross weight not measured. Ground clearance 140 mm. Tank 106 L. Wheels not measured.
140 mm is the clearance of this Coupe; there is no raised generation. 106 L is large relative to a 1620 kg kerb, but without consumption it does not convert to touring range. Missing wheel size means tyre cost and load rating cannot be compared across versions — there are no other versions.
Generations: what changed (one generation)
1 generation ran 1989-01-01 to 1994-12-31, body Coupe, 1 modification. No restyling is listed as a separate generation. Years of production for 6.0 AT match the generation: 1989-01-01 to 1994-12-31. Nothing in the data shows a later gearbox, a second displacement, or a weight cut. You cannot “wait for the facelift” inside this catalogue row.
Which version to choose
Choose 6.0 AT if the arithmetic fits: ~106.1 hp/L, ~143.0 Nm/L, ~2.56 kg/hp, 4.3 s, 350 km/h, RWD, 3-speed Automatic, Turbo Gasoline 8 V-shaped, 1620 kg, 140 mm, 106 L tank, fuel 95.
Do not invent a second pick. There is no lower-hp 6.0 AT, no manual, no other cylinder count, and no generation with different Disc / Drum or spring layout. Problems, reliability, and used prices are not measured in this dataset — they are not hidden in another trim.
If 4.3 s, 350 km/h, and 634 hp at 1620 kg are the point of the car, 6.0 AT is the version. If you need a measured mpg figure, a second gearbox, or a different drive, this model line does not provide another row to buy.
