Which MG RV8 version to buy: 4.0 MT specs, power-to-weight, and what you actually get
There is one MG RV8 to choose: 4.0 MT. The catalogue lists 1 generation, 1 body (Roadster), and 1 version. You cannot pick a weaker engine, an automatic, a different drive layout, or a restyle year — those rows are not in the data.
There is one MG RV8 to choose: 4.0 MT. The catalogue lists 1 generation, 1 body (Roadster), and 1 version. You cannot pick a weaker engine, an automatic, a different drive layout, or a restyle year — those rows are not in the data. The buying question therefore collapses to whether 4.0 MT numbers fit what you want: 190 hp and 318 Nm from 3947 cm³ Gasoline, Manual 5, RWD, 6 s to 100 km/h, 217 km/h top speed, kerb 1100 kg. Fuel consumption (city, highway, combined), CO2, eco class, and wheel sizes are not measured.
MG RV8 generations: is there a later year that changed the spec?
No. pokoleniy is 1. Generation 1 generation ran from 1993-03-01 to 1995-11-30, body Roadster, modifikaciy 1. There is no second generation to compare, and no restyling listed inside this generation. The single version 4.0 MT is dated 1992-01-01 to 1995-12-31 in the version record — that is the only production window attached to the engine row.
What a later generation would usually change (power, gearbox, drive, weight, tank, clearance) cannot be measured here: there is no later row. Arithmetic between generations is therefore not measured. The only comparison that exists is 4.0 MT against the same 4.0 MT.
MG RV8 engine specs: the only version named 4.0 MT
Use the version name exactly as in the database: 4.0 MT. There is not a second 4.0 MT with a different horsepower figure, so you do not need a power suffix to tell two names apart.
| Version | hp | Nm | Displacement, cm³ | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 4.0 MT | 190 | 318 | 3947 | Gasoline | 8 | V-shaped | No | Manual | RWD |
Further engine figures that sit on the same 4.0 MT row:
- Power: 190 hp / 140 kW at 4750 rpm
- Torque: 318 Nm at 3200 rpm
- Valves per cylinder: 2
- Fuel system: Distributed injection (multi-point)
- Compression ratio: 9.35
- Bore × stroke: 94 × 71.12
- Fuel grade: 95
- Engine location: not measured
- Gears: 5 (Manual)
Power per litre for 4.0 MT: 190 hp ÷ (3947 / 1000) = 48.1 hp per litre (rounded from 48.137). In kilowatts: 140 ÷ 3.947 = 35.5 kW per litre (rounded from 35.470). That is the specific output of this naturally aspirated Gasoline 8 V-shaped engine with Boost No. There is no turbo or supercharged alternative in the table to buy instead.
Torque arrives 1550 rpm earlier than peak power (3200 vs 4750). Peak torque per litre: 318 ÷ 3.947 = 80.6 Nm per litre (rounded from 80.568).
Two valves per cylinder on 8 cylinders is 16 valves in total (8 × 2). That count is arithmetic on the given fields, not an extra catalogue row.
Performance, mpg, and 0-100: what 4.0 MT measures and what it does not
4.0 MT acceleration 0–100: 6 s. Top speed: 217 km/h.
City fuel consumption: not measured. Highway fuel consumption: not measured. Combined fuel consumption: not measured. CO2: not measured. Eco class: not measured.
If the buying decision is “which version uses less fuel,” the data cannot rank versions: there is only 4.0 MT, and mpg figures are not measured. Do not treat a missing mpg cell as zero consumption.
What you can still compute without inventing a consumption figure:
- Fuel tank: 51 L.
- Without a measured L/100 km, range is not measured.
- Time from 0 to 100 km/h of 6 s at kerb 1100 kg with 190 hp is the only sprint figure on the sheet.
Speed in km/h per hp: 217 ÷ 190 = 1.14 km/h per hp (rounded from 1.142). That ratio is unique to 4.0 MT because no other power/speed pair exists.
Dimensions, weight, ground clearance, tank, wheels
Kerb weight 4.0 MT: 1100 kg. Gross weight: 1280 kg. Payload (gross − kerb): 1280 − 1100 = 180 kg. Ground clearance: 110 mm. Tank: 51 L. Wheel sizes: not measured.
Weight per horsepower: 1100 ÷ 190 = 5.79 kg per hp (rounded from 5.789). Horsepower per tonne of kerb weight: 190 ÷ (1100 / 1000) = 172.7 hp per tonne (rounded from 172.727). Gross-weight power loading: 1280 ÷ 190 = 6.74 kg per hp (rounded from 6.737).
At full mass the car is 180 kg heavier than kerb, which is 16.4% of kerb (180 ÷ 1100). That is the entire legal load window in the data — people, luggage, fluids above kerb — 180 kg.
Ground clearance 110 mm is the only ride-height number. There is no higher-clearance version and no lowered version to choose.
Chassis labels on 4.0 MT:
- Front suspension: Independent, spring
- Rear suspension: Independent, spring
- Front brakes: Ventilated disc
- Rear brakes: Disc
(The rear-brake English label is taken from the data as written: Disc.)
Which MG RV8 version to choose
Choose 4.0 MT, because the catalogue does not contain another version.
That is not a slogan. It is the count: 1 generation × 1 modification. Comparisons that usually decide a purchase — petrol vs diesel, Manual vs Automatic, RWD vs another drive, 4.0 vs a smaller engine — are not measured as differences because the second side of each pair is absent.
What the extra money would buy — if there were another row
There is no second price and no second spec, so “what the extra money buys” between versions is not measured. Inside 4.0 MT itself, the numbers you are paying for (whatever the market asks — prices are not in this dataset and are not stated here) are:
- 190 hp at 4750 rpm and 318 Nm at 3200 rpm
- 3947 cm³, Gasoline, 8 cylinders, V-shaped, Boost No
- Distributed injection (multi-point), compression 9.35, bore × stroke 94 × 71.12, fuel 95
- Manual 5, RWD
- 6 s to 100 km/h, 217 km/h
- Kerb 1100 kg, gross 1280 kg, clearance 110 mm, tank 51 L
- Independent, spring front and rear; Ventilated disc front; Disc rear
Reliability and problems
Reliability scores, common faults, recall lists, and service intervals are not measured in the launch data. A buying article cannot rank 4.0 MT as “more reliable than” a sibling that does not exist, and it cannot invent failure modes. The mechanical description you can hold to is: Gasoline 8 V-shaped, 2 valves per cylinder, Boost No, Manual 5, RWD, production of generation 1 generation from 1993-03-01 to 1995-11-30.
Who 4.0 MT fits, using only these numbers
- If you want the lightest power loading in this model line: 4.0 MT is the line. 5.79 kg/hp at kerb 1100 kg and 190 hp.
- If you want an automatic: not in the data. Gearbox is Manual, 5 gears.
- If you want AWD or another drive: not in the data. Drive is RWD.
- If you want a smaller engine or less displacement: not in the data. Displacement is 3947 cm³.
- If you want boost: Boost is No. Specific output stays 48.1 hp/L.
- If you want a four-door or a closed body: body is Roadster only.
- If you choose by mpg: city, highway, and combined are not measured.
- If you choose by wheels or tyre size: wheel sizes are not measured.
- If you choose by how much you can carry: payload 180 kg on gross 1280 kg.
- If you choose by ground clearance: 110 mm, one figure, no alternative.
- If you choose by tank size: 51 L, one figure, no alternative.
Arithmetic recap for 4.0 MT (so a pulled paragraph stays true)
MG RV8 4.0 MT: 190 hp (140 kW) at 4750 rpm, 318 Nm at 3200 rpm, 3947 cm³ Gasoline, 8 cylinders V-shaped, 2 valves per cylinder, Boost No, compression 9.35, bore × stroke 94 × 71.12, fuel 95, Distributed injection (multi-point), Manual 5, RWD. 48.1 hp/L. Kerb 1100 kg → 5.79 kg/hp and 172.7 hp/tonne. Gross 1280 kg → payload 180 kg. 0–100 6 s, top speed 217 km/h. Tank 51 L. Clearance 110 mm. Consumption, CO2, eco class, wheels, engine location: not measured. Generation: 1 generation, Roadster, 1993-03-01–1995-11-30. Version dates: 1992-01-01–1995-12-31. Other named versions: none.
There is no “base vs range-topper” spread in horsepower, newton-metres, or kilograms. The spread is zero because the version count is 1. Buy 4.0 MT if those measured figures are the car you want; do not wait for a second MG RV8 row in this catalogue — it is not listed.
