MG 6

MG 6: which version to buy

The MG 6 was sold as one generation of Sedan from 2010-01-01 to 2017-12-31, with nine catalogue versions. There is no second generation in this data, so the choice is not “which year of body” but which 1.8 MT, 1.8 AT, or 1.9 MT powertrain, and — where two rows share the same name — which power and weight row. Every figure below is from that list; missing values are written as not measured.

Specs that actually separate the nine versions

All nine cars are FWD. Gasoline engines are 1796 cm³, Inline, 4 cylinders, 4 valves per cylinder, front transverse, multi-point injection, 80 × 89.3 mm bore and stroke, 95 fuel. The diesel is 1849 cm³, Inline, 4 cylinders, 4 valves per cylinder, Turbo, Diesel fuel; engine position and bore × stroke are not measured. Tank is 62 L and ground clearance is 135 mm on every row. Wheel sizes are not measured.

The two 1.9 MT 150 hp rows are identical on every measured field. Buying “the other diesel” is not a real choice in this catalogue.

Engine: 133 vs 160 vs 150 — what the extra power buys

Specific output from the given displacements:

• 1.8 MT / 1.8 AT 133 hp: 133 ÷ 1.796 ≈ 74.1 hp per litre, no boost.
• 1.8 MT / 1.8 AT 160 hp: 160 ÷ 1.796 ≈ 89.1 hp per litre, Turbo. That is +27 hp and +19.1% specific output versus the naturally aspirated 1.8, and +45 Nm (215 vs 170). Peak torque arrives from 2500 rpm instead of a single 4500 rpm point.
• 1.9 MT 150 hp: 150 ÷ 1.849 ≈ 81.1 hp per litre. Peak power is 17 hp below the turbo petrol, but torque is 350 Nm vs 215 Nm — +135 Nm, +63%. Peak torque is at 1800 rpm, 700 rpm earlier than the turbo petrol’s lower edge.

Power-to-weight (kerb kg per hp, lower is quicker on paper):

• Lightest 1.8 MT 160 hp: 1486 ÷ 160 = 9.29 kg/hp
• Heavier 1.8 MT 160 hp: 1520 ÷ 160 = 9.50 kg/hp
• Light 1.8 AT 160 hp: 1522 ÷ 160 = 9.51 kg/hp
• Heavy 1.8 AT 160 hp: 1540 ÷ 160 = 9.63 kg/hp
• 1.9 MT 150 hp: 1615 ÷ 150 = 10.77 kg/hp
• Lightest 1.8 MT 133 hp: 1473 ÷ 133 = 11.08 kg/hp
• Heavy 1.8 MT 133 hp: 1510 ÷ 133 = 11.35 kg/hp
• 1.8 AT 133 hp: 1535 ÷ 133 = 11.54 kg/hp

The turbo petrol manuals are the only cars under 9.5 kg/hp. The diesel is heavier by 129 kg than the light 160 hp 1.8 MT (1615 − 1486) and by 142 kg than the light 133 hp 1.8 MT (1615 − 1473). That extra mass is why 150 hp and 350 Nm still sit in the middle of the kg/hp ranking, not at the top.

Performance: 0–100 and top speed, version by version

Fastest 0–100 in the data is 8.9 s on both 1.9 MT 150 hp rows. Next is the light 1.8 MT 160 hp at 9.2 s (+0.3 s). The heavier turbo manual is 9.4 s (+0.5 s vs diesel, +0.2 s vs its light twin). Automatic turbo petrols are 10.6 s and 10.8 s — 1.4 s and 1.6 s slower than the light turbo manual, 1.7 s and 1.9 s slower than the diesel.

Naturally aspirated cars are a step slower: 11.5 s and 11.8 s for the two 1.8 MT 133 hp rows, 12.2 s for 1.8 AT 133 hp. From the quickest petrol turbo manual to the 133 hp automatic the gap is 12.2 − 9.2 = 3.0 s. From diesel to 133 hp automatic it is 12.2 − 8.9 = 3.3 s.

Top speed does not follow 0–100. All 160 hp petrols are 205 km/h. The diesel is 193 km/h — 12 km/h slower than the turbo petrol despite winning the sprint. All 133 hp cars are 188 km/h — 17 km/h below the turbo petrol and 5 km/h below the diesel.

If the decision is “shortest 0–100,” the data point to 1.9 MT 150 hp. If it is “highest listed speed,” it is any 160 hp 1.8 MT or 1.8 AT. Those two goals do not pick the same car.

MPG and fuel: city, highway, mixed

Mixed consumption:

• 1.9 MT 150 hp: 4.4 L/100 km (city 5.1, highway 4)
• Light 1.8 MT 133 hp: 7.4 (10.1 / 6)
• Light 1.8 MT 160 hp: 7.6 (10.3 / 6.2)
• Heavy 1.8 MT 160 hp: 7.7 (10.6 / 6.3)
• Heavy 1.8 MT 133 hp: 7.8 (10.7 / 6.4)
• Both 1.8 AT 160 hp: 7.9 (10.7 / 6.5 and 10.9 / 6.5)
• 1.8 AT 133 hp: 8.3 (11.4 / 6.7)

Diesel vs light turbo petrol mixed: 7.6 − 4.4 = 3.2 L/100 km. Versus the thirstiest petrol (1.8 AT 133 hp): 8.3 − 4.4 = 3.9 L/100 km. City gap diesel vs that automatic: 11.4 − 5.1 = 6.3 L/100 km. Highway: 6.7 − 4.0 = 2.7 L/100 km.

Among petrols, Turbo does not cost much mixed fuel versus No boost on a manual: light 160 hp 1.8 MT is only 0.2 L/100 km above the light 133 hp 1.8 MT (7.6 vs 7.4), while adding 27 hp and cutting 0–100 from 11.5 s to 9.2 s. The expensive petrol in this table is the automatic on the weak engine: 1.8 AT 133 hp uses 0.9 L/100 km more mixed than the light 133 hp manual and 0.4 more than the 160 hp automatics, while being the slowest car (12.2 s, 188 km/h).

Tank is 62 L on every version. CO2 and eco class are not measured on all nine, so range and emissions cannot be compared from this data.

Dimensions and weight: what you haul

Kerb weight span: 1473 kg (light 1.8 MT 133 hp) to 1615 kg (1.9 MT). Spread: 142 kg.

Gross weight is measured on petrols only, from 1848 kg to 1915 kg. Payload (gross − kerb) on those rows:

• Light 1.8 MT 133: 1848 − 1473 = 375 kg
• Light 1.8 MT 160: 1861 − 1486 = 375 kg
• Heavy 1.8 MT 133: 1885 − 1510 = 375 kg
• Light 1.8 AT 160: 1897 − 1522 = 375 kg
• Heavy 1.8 MT 160: 1895 − 1520 = 375 kg
• 1.8 AT 133: 1910 − 1535 = 375 kg
• Heavy 1.8 AT 160: 1915 − 1540 = 375 kg

Petrol payload is the same 375 kg wherever gross is listed. 1.9 MT gross is not measured, so diesel payload is not measured.

Pairs that share a name differ by kerb, not by engine:

• Two 1.8 MT 133 hp: 1510 − 1473 = 37 kg; 0–100 +0.3 s; mixed +0.4 L/100 km.
• Two 1.8 MT 160 hp: 34 kg; +0.2 s; +0.1 L/100 km.
• Two 1.8 AT 160 hp: 18 kg; +0.2 s; mixed both 7.9.

If two cars are both labelled 1.8 MT 160 hp, the lighter row is the one to take on the numbers. Ground clearance does not help choose: 135 mm across the board. Wheel size is not measured.

Chassis language is the same on every row: Independent, spring front and rear; Ventilated disc front; rear listed as ventilated disc in the source. Suspension and brakes do not split the range.

Manual vs Automatic on the same engine

1.8 AT exists at 133 hp and 160 hp. There is no automatic diesel.

133 hp, lightest manual vs automatic: Automatic is 62 kg heavier (1535 − 1473), 0.7 s slower (12.2 vs 11.5), same 188 km/h, mixed +0.9 L/100 km (8.3 vs 7.4). City +1.3 (11.4 vs 10.1).

160 hp, lightest manual vs lightest automatic: Automatic is 36 kg heavier (1522 − 1486), 1.4 s slower (10.6 vs 9.2), same 205 km/h, mixed +0.3 (7.9 vs 7.6). Versus the heavier turbo manual (9.4 s, 1520 kg), the light automatic is still 1.2 s slower at almost the same kerb (1522 vs 1520).

Gear count: petrols are 5-speed Manual or 5-speed Automatic. 1.9 MT is the only 6-speed, Manual. There is no 6-speed petrol in the data.

The automatic buys you the Automatic label and, on the 160 hp engine, the same 205 km/h as the manual. It does not buy better 0–100, better mixed fuel, or more gears.

Which version to choose

If 0–100 and mixed fuel both matter: 1.9 MT 150 hp. It is the only Diesel, the only 6-speed, the only 350 Nm, the only 8.9 s, and the only 4.4 L/100 km mixed. Cost of that choice in the table: 1615 kg kerb (heaviest), 193 km/h (12 km/h below turbo petrol), engine layout and bore × stroke not measured, gross weight not measured. The second 1.9 MT row is the same car on paper.

If top speed and kg/hp matter more than diesel economy: light 1.8 MT 160 hp — 9.2 s, 205 km/h, 7.6 mixed, 1486 kg, 9.29 kg/hp. Versus its heavier twin: 34 kg, 0.2 s, 0.1 L/100 km. Versus light 1.8 AT 160 hp: 1.4 s and 0.3 L/100 km saved by staying Manual. Versus 1.9 MT: you give up 0.3 s and 3.2 L/100 km mixed to gain 12 km/h and 129 kg less kerb.

If you want Automatic and still want the 160 hp Turbo: light 1.8 AT 160 hp (10.6 s, 1522 kg, 7.9 mixed) over the heavier 1.8 AT 160 hp (10.8 s, 1540 kg, same 7.9). Do not buy 1.8 AT 133 hp for “economy with an automatic”: it is the slowest (12.2 s) and thirstiest mixed (8.3) petrol in the list, 8 hp/L weaker than the 160 hp Automatic, and only 188 km/h.

If you want the lightest, simplest petrol: light 1.8 MT 133 hp — 1473 kg, No boost, 7.4 mixed (best petrol mixed). You give up 27 hp, 45 Nm, 2.3 s to 100 versus the light turbo manual, and 3.0 s versus the same engine in 1.8 AT 133 hp is even worse. The heavier 1.8 MT 133 hp is the same engine with 37 kg, 0.3 s, and 0.4 L/100 km mixed extra; there is no performance reason to pick it over the 1473 kg row.

What generation does not change: there is one generation (2010–2017, Sedan, nine versions). Restyling is not listed as a separate generation. Chassis, tank, clearance, drive, and petrol architecture stay put; the arithmetic lives in boost (No vs Turbo), fuel (Gasoline vs Diesel), gearbox (Manual vs Automatic), and the 37 / 34 / 18 kg name-twins.

Prices are not in this data, so “extra money” here means extra kilograms, extra seconds, extra litres, or extra newton-metres — not a sticker. Reliability and common problems are not measured in this dataset.
