Bentley Brooklands

Which Bentley Brooklands to buy: 6.8 AT 248 hp, 6.8 AT 305 hp, or the Coupe 6.8 AT 537 hp

The Bentley Brooklands buyer is choosing among three petrol 6.8 AT cars, not among body styles or extra engines. Generation 1 (1992–1998) is a Sedan with two 6.8 AT versions: 248 hp and 305 hp. Generation 2 (2007–2009) is a Coupe with one 6.8 AT at 537 hp. Same name, three power figures: 248, 305, 537. That is the whole catalogue.

Which Bentley Brooklands to buy: 6.8 AT 248 hp, 6.8 AT 305 hp, or the Coupe 6.8 AT 537 hp

The Bentley Brooklands buyer is choosing among three petrol 6.8 AT cars, not among body styles or extra engines. Generation 1 (1992–1998) is a Sedan with two 6.8 AT versions: 248 hp and 305 hp. Generation 2 (2007–2009) is a Coupe with one 6.8 AT at 537 hp. Same name, three power figures: 248, 305, 537. That is the whole catalogue.

There is no measured price in this dataset, so “what the extra money buys” is what the extra horsepower, torque, gears, and seconds buy. There is no convertible in the data. Wheel size is not measured on any version. Fuel use is not measured on either generation-1 6.8 AT. Those gaps stay written as not measured.

Generations: what actually changed between the Sedan and the Coupe

1 generation (1992–1998), Sedan, two versions. Both are 6.8 AT, Gasoline, Turbo, 8 cylinders, V-shaped, 2 valves per cylinder, Front, longitudinal, Distributed injection (multi-point), Automatic with 4 gears, RWD. Both use 95 fuel, compression 8, bore × stroke 101.1 × 99.1, displacement 6750, tank 107 L, kerb 2470 kg, gross 2970 kg, ground clearance 140 mm, 0–100 9.5 s. Front and rear brakes are Disc. Front and rear suspension are Independent, spring. Wheel size is not measured. City / highway / mixed consumption is not measured. CO2 is not measured. Eco class is not measured. The two cars split only on output and top speed: 248 hp / 180 kW at 4000 rpm and 503 Nm at 1900 rpm with 214 km/h, versus 305 hp / 224 kW at 4000 rpm and 605 Nm at 2000 rpm with 225 km/h. Same 0–100, same mass. The 57 hp and 102 Nm do not shorten the 0–100 figure in this dataset; they add 11 km/h at the top.

2 generation (2007–2009), Coupe, one version. One 6.8 AT: 537 hp / 395 kW at 4000 rpm, 1050 Nm at 3250 rpm, 6761 cc, Gasoline, Turbo, 8, V-shaped, 2 valves, Front, longitudinal, Distributed injection (multi-point), Automatic with 6 gears, RWD, 98 fuel, compression 7.8, bore × stroke 104.2 × 99.1, 0–100 5.3 s, top speed 296 km/h. City 28.8, highway 14.1, mixed 19.5 L/100 km. Tank 96 L. Kerb 2550 kg, gross 3050 kg, clearance 140 mm. Independent, spring front and rear. Ventilated disc front and rear. Wheels not measured. CO2 not measured. Eco class not measured. Generation span in the generation block is 2007–2009; this modification’s own start–stop is 2007–2011.

Across generations the catalogue does not add a second body to generation 2 or a third engine family. It adds 232 hp over the stronger Sedan (537 − 305), 445 Nm (1050 − 605), 2 extra gears, 11 cc, a 3.1 mm larger bore (104.2 − 101.1), 80 kg more kerb and 80 kg more gross, 11 L less tank, 98 instead of 95, compression 0.2 lower (8 − 7.8), ventilated discs instead of discs, and 4.2 s off 0–100 (9.5 − 5.3). Clearance does not change: 140 mm on all three.

Bentley Brooklands engine and specs: three 6.8 AT rows

Use the names exactly as in the data. Distinguish the two identical 6.8 AT labels by horsepower.

Power per litre (hp ÷ displacement in litres): 6.8 AT 248 hp = 248 / 6.750 ≈ 36.7 hp/L. 6.8 AT 305 hp = 305 / 6.750 ≈ 45.2 hp/L. Coupe 6.8 AT 537 hp = 537 / 6.761 ≈ 79.4 hp/L. The 305 hp Sedan is 8.5 hp/L above the 248 hp Sedan. The Coupe is 34.2 hp/L above the 305 hp Sedan and 42.7 hp/L above the 248 hp Sedan.

Peak power rpm is 4000 on all three. Torque rpm is not: 1900 (248 hp), 2000 (305 hp), 3250 (Coupe). The Coupe’s 1050 Nm arrives 1250 rpm later than the 305 hp Sedan’s 605 Nm, and 1350 rpm later than the 248 hp car’s 503 Nm.

Performance, mpg, horsepower: what the extra output buys

0–100. Both generation-1 6.8 AT cars are 9.5 s. The Coupe 6.8 AT is 5.3 s — 4.2 s quicker, 44% less time (4.2 / 9.5). Inside generation 1, +57 hp and +102 Nm do not change 0–100 in this dataset. If the question is “faster to 100,” only generation 2 answers it with a different number.

Top speed. 214 km/h (248 hp) → 225 km/h (305 hp) → 296 km/h (537 hp). Generation 1’s extra 57 hp buys 11 km/h. Generation 2’s extra 232 hp over the 305 hp car buys 71 km/h (296 − 225). Versus the 248 hp car the Coupe is 82 km/h faster (296 − 214).

Horsepower and torque steps. 248 → 305 is +23% power (57 / 248) and +20% torque (102 / 503). 305 → 537 is +76% power (232 / 305) and +74% torque (445 / 605). 248 → 537 is +117% power (289 / 248) and +109% torque (547 / 503).

mpg / fuel use. Generation-1 6.8 AT (248 hp): city not measured, highway not measured, mixed not measured. Generation-1 6.8 AT (305 hp): city not measured, highway not measured, mixed not measured. You cannot pick the 248 hp over the 305 hp on economy from this catalogue. Generation-2 6.8 AT: city 28.8, highway 14.1, mixed 19.5 L/100 km. Those three figures exist only for the Coupe. Tank 96 L on the Coupe versus 107 L on both Sedans (11 L less). Mixed range arithmetic on the Coupe only: 96 / 19.5 ≈ 4.92 hundred kilometres of mixed use per tank, i.e. about 492 km of mixed distance per fill if mixed 19.5 holds. Generation 1 range cannot be calculated: consumption is not measured.

Dimensions, weight, size: kerb weight vs horsepower

Length, width, height, and wheel size are not measured on any Brooklands version here. What is measured is mass, clearance, and tank.

Payload is 500 kg on all three. Ground clearance is 140 mm on all three. The Coupe is 80 kg heavier at the kerb and 80 kg heavier gross. You do not buy extra payload or extra clearance by moving generation.

Kerb weight per horsepower: 6.8 AT 248 hp = 2470 / 248 ≈ 9.96 kg/hp. 6.8 AT 305 hp = 2470 / 305 ≈ 8.10 kg/hp. Coupe 6.8 AT = 2550 / 537 ≈ 4.75 kg/hp. The 305 hp Sedan carries 1.86 kg less per horsepower than the 248 hp Sedan with zero extra kerb. The Coupe carries 3.35 kg less per horsepower than the 305 hp Sedan even after adding 80 kg. Gross per horsepower: 2970 / 248 ≈ 12.0 kg/hp, 2970 / 305 ≈ 9.74 kg/hp, 3050 / 537 ≈ 5.68 kg/hp.

Which version to choose

Choose generation-1 Sedan 6.8 AT (248 hp) if you want the same measured chassis numbers as the other Sedan at the lowest output in this file: 248 hp, 503 Nm, 214 km/h, 9.5 s, 2470 kg, 107 L, 4-speed Automatic, RWD, 95, Disc brakes. You give up 57 hp, 102 Nm, and 11 km/h versus the other 6.8 AT of the same generation, and you do not get a better 0–100 or a lighter kerb — those two are identical. You also accept that mpg is not measured.

Choose generation-1 Sedan 6.8 AT (305 hp) if you are staying in 1992–1998 and the only measured gains you need are power, torque, and top speed. Same 6750 cc, same 9.5 s, same 2470 / 2970 kg, same 140 mm, same 107 L, same 4 gears, same RWD. Specific output rises from 36.7 to 45.2 hp/L; kg/hp falls from 9.96 to 8.10. That is the entire generation-1 decision: +57 hp, +102 Nm, +11 km/h, nothing else in the table moves.

Choose generation-2 Coupe 6.8 AT (537 hp) if the question is Coupe versus Sedan, 2007–2009 (modification window to 2011) versus 1992–1998, and you want the only car here with a different 0–100 and a measured mpg set. You buy 537 hp, 1050 Nm, 6 gears, 5.3 s, 296 km/h, Ventilated disc brakes, 98 fuel, 79.4 hp/L, 4.75 kg/hp. You pay 80 kg extra kerb, 11 L less tank, torque peak 1250 rpm later than the 305 hp Sedan, and you still have 140 mm clearance and 500 kg payload. City 28.8 / highway 14.1 / mixed 19.5 are the only consumption numbers in the model; they are not a reason to prefer this car over generation 1 on economy, because generation 1 consumption is not measured.

Do not choose on these searches: convertible — not in the data. Price / for sale / USA listings — not measured. Production numbers — not measured. Interior — not in the data. Wheel size / full exterior dimensions — not measured. Brooklands versus Turbo R — Turbo R is not in this file. Reliability / problems — not in this file.

Short arithmetic recap. Same name 6.8 AT three times. Generation 1: two outputs, one 0–100 (9.5), one mass (2470). Generation 2: one output that more than doubles the weakest car’s horsepower (537 / 248 ≈ 2.17), cuts 0–100 by 4.2 s, raises top speed by 82 km/h versus 214, and almost halves kg/hp (9.96 → 4.75). If you need a Sedan, the 305 hp 6.8 AT is the higher-output twin of the 248 hp 6.8 AT. If you need the Coupe, there is only the 537 hp 6.8 AT.
