Byvin BD326J: which version to buy (AT, 2011–2016)

There is one Byvin BD326J to choose: AT, 5 hp / 4 kW Electro, 13 Nm, Automatic, RWD, Mini 3-doors, sold across 1 generation from 2011-01-01 to 2016-12-31. If you came here to pick between engines, gearboxes, or later restyles, the catalogue does not give a second row to compare.

There is one Byvin BD326J to choose: AT, 5 hp / 4 kW Electro, 13 Nm, Automatic, RWD, Mini 3-doors, sold across 1 generation from 2011-01-01 to 2016-12-31. If you came here to pick between engines, gearboxes, or later restyles, the catalogue does not give a second row to compare. The decision is not “which BD326J,” it is whether AT matches the job: 45 top speed, 780 kerb weight, 150 ground clearance, and a set of figures that are not measured.

Which generation of BD326J to buy

1 generation is the only generation. It ran 2011-01-01 to 2016-12-31, Mini 3-doors, 1 version (AT). There is no second generation, no restyle listed as its own generation, and no later body. Year-to-year “which generation changed what” arithmetic is zero: start and stop of the generation and of AT are the same dates (2011-01-01–2016-12-31). Buying an early car versus a late car does not change hp, Nm, drive, gearbox, weight, or clearance in this data.

AT is named AT in the database — keep that string. There is not a second AT with a different horsepower, so you do not split this name by power.

What the extra money would buy: with 1 version, it buys nothing extra inside the model. 5 hp is 5 hp; 4 kW is 4 kW; 13 Nm is 13 Nm. Power per litre is not measured because displacement is not measured. Cylinders, cylinder layout, boost, engine placement, and compression are not measured — do not fill them from other cars.

Engine and gearbox: what AT actually is

AT is Electro, not a petrol or diesel row. Fuel volume, tank size, city / highway / combined consumption, CO2, and eco class are not measured. Comparing mpg between versions is not possible: there is one powertrain and no fuel figures.

Gearbox is Automatic; number of gears is not measured. Drive is RWD. You cannot choose FWD or AWD inside BD326J. You cannot choose a manual. The Automatic + RWD pair is the whole driveline set.

5 hp versus 4 kW is the same AT motor stated two ways, not two motors. 13 Nm is the torque figure; rpm for power and torque are not measured, so you cannot rank this motor by where peak sits.

Performance: 0-100, top speed, and what is not measured

0–100 for AT is not measured. Do not treat a missing sprint as “slow 0–100”; it is unmeasured.

Top speed is 45. That is the only speed number in the file. With 5 hp and 780 kg, mass per horsepower is 156 kg/hp (780 ÷ 5). Mass per kW is 195 kg/kW (780 ÷ 4). Those ratios are arithmetic on catalogue numbers, not extra tests. They explain why the buyer question is not “which BD326J is quicker” but whether 45 top speed is enough. There is no second version with a higher top speed to pay for.

Fuel consumption (city, highway, mixed) is not measured. Tank is not measured. If your search is “BD326J mpg,” the honest answer is: not measured on AT.

Dimensions, weight, and clearance: what you are buying with AT

Kerb weight AT: 780. Gross weight: not measured. You cannot compute payload (gross minus kerb) because gross is not measured.

Ground clearance AT: 150. Wheel sizes: not measured. Rear suspension: not measured. Front suspension: Independent, spring. Front brakes: Disc. Rear brakes: Drum.

There is no second BD326J with more clearance, less weight, or different wheels. “Which version rides higher” is 150 or nothing. “Which version is lighter” is 780 or nothing.

If you compare 150 clearance to the 45 top speed as two constraints on the same AT, they do not trade against another trim: both apply together. A lighter or faster Mini 3-doors is not in this generation’s 1 version list.

Which version to choose

Choose AT if all of the following match the use: Electro, Automatic, RWD, Mini 3-doors, 5 hp / 4 kW, 13 Nm, 45 top speed, 780 kerb weight, 150 clearance, Independent, spring front, Disc front / Drum rear, years 2011-01-01–2016-12-31.

Do not choose a “different BD326J” for more power: there is no 6 hp, 7 hp, or second AT. Do not choose a later generation for a restyle: 1 generation only. Do not choose a petrol BD326J: fuel is Electro, displacement not measured. Do not choose by mpg, 0–100, tank, wheels, cylinder count, or boost — those are not measured.

What the numbers do not buy: extra gears (gears not measured), extra driven wheels (RWD only), extra doors (Mini 3-doors only), extra generations (1). The arithmetic that would normally rank versions — hp per litre, extra hp for extra money, generation-to-generation weight cut — has one row. hp per litre = not measured. Extra hp versus another version = 0. Weight change versus another generation = 0.

Reliability and problems (what this catalogue can and cannot say)

This file does not list faults, recalls, or reliability scores. Saying AT is “more reliable” than another BD326J is not possible: there is no other version. Age of a 2011 car versus a 2016 car is a calendar fact (production window 2011-01-01–2016-12-31), not a reliability ranking in the data.

What you can hold onto: one Electro Automatic RWD Mini 3-doors, 5 hp, 4 kW, 13 Nm, 45 top speed, 780 kg, 150 mm clearance. If that set is the car you want, the version to buy is AT. If you need a figure marked not measured, this model’s catalogue row does not supply it.

BD326J buyer checklist (AT only)

If a listing uses another name, it is not a second catalogue version here. The Byvin BD326J choice, on these numbers, is AT or a different model.
