Which Alpina B9 Version Should You Buy?
The Alpina B9 catalogue data contains one generation and one version, the 3.4 MT. This means there is no alternative B9 engine, transmission, body style, or generation to compare within the supplied range. For a buyer choosing strictly from this catalogue, the decision is therefore straightforward: the 3.4 MT is the only available specification.
The Alpina B9 catalogue data contains one generation and one version, the 3.4 MT. This means there is no alternative B9 engine, transmission, body style, or generation to compare within the supplied range. For a buyer choosing strictly from this catalogue, the decision is therefore straightforward: the 3.4 MT is the only available specification. It combines a Sedan body with a 3,430 cc Gasoline engine, 240 hp, 310 Nm, a 5-speed Manual gearbox, and RWD. It accelerates from 0 to 100 km/h in 6.7 seconds and has a top speed of 240 km/h. Price and sale-listing data are not provided, so this catalogue cannot determine market value or whether a particular car is fairly priced.
Alpina B9 generations compared
The Alpina B9 has 1 generation in the supplied data. The 1 generation ran from November 1981 through December 1985, used a Sedan body, and included 1 version. Because there is no second generation in the catalogue, there are no documented generational changes to compare and no later B9 specification that can be recommended over an earlier one.
The sole 3.4 MT version is dated from 1981 through 1985. The generation’s recorded start is November 1981, while the version entry begins in January 1981. Both dates are reported exactly as supplied. No restyling is listed, so there is no separate pre-restyling or post-restyling choice.
Alpina B9 engine and specs
The 3.4 MT uses a 3,430 cc Gasoline engine with 6 cylinders in an Inline layout and 4 valves per cylinder. Its output is 240 hp, or 176 kW, at 5,700 rpm, while peak torque is 310 Nm at 4,500 rpm. The fuel system is Distributed injection (multi-point). Boost, engine position, compression ratio, bore and stroke, and fuel grade are not measured.
Based on the supplied displacement and power figures, the 3.4 MT produces approximately 70.0 hp per litre. Its specific torque is approximately 90.4 Nm per litre. These calculated figures are useful for describing how much output the sole engine develops from its capacity, but they cannot rank it against another B9 version because no other version is present in the data.
| Version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 3.4 MT | 240 hp | 310 Nm | 3,430 cc | Gasoline | 6 | Inline | not measured | 5-speed Manual | RWD |
The exact version name is 3.4 MT. Although searches may use other displacement labels, the supplied catalogue does not contain a version with any other name. Such search wording should not be treated as a confirmed specification.
Alpina B9 performance and mpg
The 3.4 MT accelerates from 0 to 100 km/h in 6.7 seconds and reaches a maximum speed of 240 km/h. With only one version available, neither figure represents an advantage over another B9 in this catalogue; they define the performance of the entire listed range.
City fuel consumption is not measured. Highway fuel consumption is not measured, and combined fuel consumption is also not measured. Consequently, no verified mpg figure or fuel-economy comparison can be provided. CO₂ emissions and environmental class are not measured as well.
A buyer cannot use the supplied data to choose between a quicker version and a more economical version. There is only the 3.4 MT, and its performance is documented while its consumption is not.
Alpina B9 dimensions and weight
Kerb weight is not measured, and gross weight is not measured. Ground clearance is not measured, fuel-tank capacity is not measured, and wheel sizes are not measured. Overall length, width, height, and wheelbase are also not measured in the supplied data.
Because kerb weight is unavailable, weight per horsepower cannot be calculated. It would therefore be misleading to assign the 3.4 MT a power-to-weight ratio or compare its mass efficiency with another car.
The chassis specification does provide several useful facts. The 3.4 MT has Independent, spring suspension at the front and Independent, spring suspension at the rear. Braking is handled by Ventilated disc brakes at the front and Disc brakes at the rear.
Alpina B9 price and cars for sale
Price is not measured, and no cars-for-sale records are included. The supplied data therefore cannot establish an Alpina B9 price, compare asking prices by year, or confirm whether any advertised vehicle matches the catalogue specification.
For catalogue identification, the relevant facts are the exact 3.4 MT version name, Sedan body, 3,430 cc Gasoline engine, 240 hp, 310 Nm, 5-speed Manual gearbox, and RWD. Any advertised specification that differs from these values cannot be validated from the supplied record.
Alpina B9 reliability and problems
Reliability results, service intervals, repair history, and documented problems are not measured. The data does not support claims about common engine faults, transmission durability, corrosion, maintenance costs, or parts availability.
The catalogue can identify the hardware that should be checked against a vehicle description: the 3.4 MT specification calls for a 6-cylinder Inline Gasoline engine, Distributed injection (multi-point), a 5-speed Manual gearbox, and RWD. It cannot determine the mechanical condition of an individual car.
Which Alpina B9 version should you choose?
Choose the 3.4 MT if you want an Alpina B9 represented by this catalogue, because it is the only listed version in the only listed generation. There is no automatic alternative, different drive system, lower-output engine, higher-output engine, or second body style to weigh against it.
The numbers describe a single, consistent proposition: 3,430 cc, 240 hp, 310 Nm, 6 Inline cylinders, 5-speed Manual, RWD, 6.7 seconds from 0 to 100 km/h, and a 240 km/h maximum speed. Its calculated output of approximately 70.0 hp per litre and torque of approximately 90.4 Nm per litre add context, but do not create a choice between versions.
The final buying decision must therefore depend on factors that this dataset does not measure, including price, condition, history, reliability, fuel consumption, and weight. On specification alone, the recommendation is unambiguous: 3.4 MT, because no other Alpina B9 version or generation is available for comparison.
