Volkswagen Derby: Which Version to Buy and Why
The Volkswagen Derby choice comes down to engine output, fuel system, and generation. The first generation, produced from 1977 to 1981, offers three Coupe versions with 40–60 hp and 95 mm of ground clearance. The second generation, produced from 1981 to 1984, expands the range to five Coupe versions with 40–75 hp and raises ground clearance to 120 mm.
The Volkswagen Derby choice comes down to engine output, fuel system, and generation. The first generation, produced from 1977 to 1981, offers three Coupe versions with 40–60 hp and 95 mm of ground clearance. The second generation, produced from 1981 to 1984, expands the range to five Coupe versions with 40–75 hp and raises ground clearance to 120 mm. Every listed Volkswagen Derby uses a Gasoline, Inline 4-cylinder, naturally aspirated engine, a 4-speed Manual gearbox, and FWD. For maximum output, choose the second-generation 1.3 MT with 1,275 cc and 75 hp. For a simpler carbureted specification, the 1.3 MT with 1,272 cc and 60 hp is the strongest option in either generation.
Volkswagen Derby generations compared
The first-generation Volkswagen Derby was offered from 1977 to 1981 as a Coupe with three versions: 0.9 MT, 1.1 MT, and 1.3 MT. Outputs rise from 40 hp in the 895 cc 0.9 MT to 50 hp in the 1,093 cc 1.1 MT and 60 hp in the 1,272 cc 1.3 MT. All three have 95 mm of ground clearance, an Independent, spring front suspension, a Semi-independent, spring rear suspension, and front Disc brakes.
The second-generation Volkswagen Derby was offered from 1981 to 1984 as a Coupe with five versions: 1.0 MT, 1.1 MT, and three distinct 1.3 MT specifications. The engines produce 40 hp, 50 hp, 60 hp, 75 hp, or 55 hp. Ground clearance is 120 mm across the range, which is 25 mm more than the 95 mm listed for the first generation. The second-generation data specifies an Independent, spring front suspension and front Disc brakes; its rear-suspension specification is not measured.
The clearest generation-to-generation comparison involves the 1.1 MT and the 60 hp 1.3 MT. Their engine displacement and output remain the same in the supplied data: the 1.1 MT has 1,093 cc and 50 hp, while the 1.3 MT has 1,272 cc and 60 hp. Their shared transmission and drivetrain also remain a 4-speed Manual and FWD. The measured change is ground clearance, which increases by 25 mm in the second generation.
Volkswagen Derby engine and specs
| Generation and version | Power | Torque | Displacement | Fuel | Cylinders and layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|
| First generation 0.9 MT | 40 hp / 29 kW | not measured | 895 cc | Gasoline, 80 | 4, Inline | No | 4-speed Manual | FWD |
| First generation 1.1 MT | 50 hp / 37 kW | not measured | 1,093 cc | Gasoline, 80 | 4, Inline | No | 4-speed Manual | FWD |
| First generation 1.3 MT | 60 hp / 44 kW | not measured | 1,272 cc | Gasoline, 80 | 4, Inline | No | 4-speed Manual | FWD |
| Second generation 1.0 MT | 40 hp / 29 kW | not measured | 1,000 cc | Gasoline, 80 | 4, Inline | No | 4-speed Manual | FWD |
| Second generation 1.1 MT | 50 hp / 37 kW | not measured | 1,093 cc | Gasoline, 80 | 4, Inline | No | 4-speed Manual | FWD |
| Second generation 1.3 MT, 60 hp | 60 hp / 44 kW | not measured | 1,272 cc | Gasoline, 80 | 4, Inline | No | 4-speed Manual | FWD |
| Second generation 1.3 MT, 75 hp | 75 hp / 55 kW at 5,900 rpm | 100 Nm at 3,200 rpm | 1,275 cc | Gasoline, 95 | 4, Inline | No | 4-speed Manual | FWD |
| Second generation 1.3 MT, 55 hp | 55 hp / 40 kW at 5,000 rpm | 100 Nm at 2,800 rpm | 1,289 cc | Gasoline; grade not measured | 4, Inline | No | 4-speed Manual | FWD |
The versions differ more clearly when output is compared with displacement. The first-generation 0.9 MT develops about 44.7 hp per litre. The first- and second-generation 1.1 MT versions each produce about 45.7 hp per litre, while both 1,272 cc 1.3 MT versions reach about 47.2 hp per litre. The second-generation 1.3 MT with 1,275 cc and 75 hp leads at about 58.8 hp per litre. The second-generation 1.3 MT with 1,289 cc and 55 hp produces about 42.7 hp per litre.
The 1.3 MT name therefore does not identify a single second-generation engine specification. The 1,272 cc version produces 60 hp and uses a Carburetor. The 1,275 cc version produces 75 hp, uses Distributed injection (multi-point), has a compression ratio of 10, and has a 75 × 72 mm bore and stroke. The 1,289 cc version produces 55 hp, uses Central injection (single-point or single- point), and has a 76.5 × 70.6 mm bore and stroke.
Volkswagen Derby performance and economy
Acceleration from 0 to 100 km/h is not measured for every listed Volkswagen Derby version. Top speed is also not measured for any version. City fuel consumption, highway fuel consumption, and combined fuel consumption are not measured throughout the range, so an mpg comparison cannot be supported by the supplied figures.
The available engine numbers still establish a performance hierarchy by output. The second-generation 1.3 MT with 75 hp has 15 hp more than the 60 hp 1.3 MT, a 25% increase. It has 20 hp more than the 55 hp 1.3 MT, an increase of about 36.4%. Compared with either 40 hp entry—the first-generation 0.9 MT or second-generation 1.0 MT—it provides 35 hp more, or 87.5% additional output.
Both torque-rated second-generation 1.3 MT versions produce 100 Nm, but at different engine speeds. The 55 hp, 1,289 cc version reaches 100 Nm at 2,800 rpm, while the 75 hp, 1,275 cc version reaches 100 Nm at 3,200 rpm. That is the same measured peak torque, with the 55 hp version reaching it 400 rpm earlier. No torque figure is measured for the other engines, so they cannot be compared on this parameter.
Volkswagen Derby dimensions and weight
Kerb weight and gross weight are not measured for any version. Consequently, weight per horsepower cannot be calculated reliably, despite power ranging from 40 hp to 75 hp. Fuel-tank capacity and wheel sizes are also not measured across both generations.
Ground clearance is the usable dimensional distinction in the data. Every first-generation version has 95 mm, whereas every second-generation version has 120 mm. Buyers choosing by clearance therefore gain 25 mm with the second generation, an increase of about 26.3% over the first-generation figure.
Other exterior dimensions are not measured. The catalogue data identifies both generations as Coupe models but does not provide measured length, width, height, or wheelbase figures.
Which Volkswagen Derby version should you buy?
Choose the second-generation 1.3 MT with 1,275 cc and 75 hp if engine output is the priority. It is the most powerful listed Volkswagen Derby, delivers the best calculated specific output at about 58.8 hp per litre, and is one of only two versions with a measured torque figure. Its specification includes 100 Nm at 3,200 rpm, Distributed injection (multi-point), a compression ratio of 10, and Gasoline, 95.
Choose the 1.3 MT with 1,272 cc and 60 hp if you prefer the strongest Carburetor version. It is available in both generations with the same 60 hp, 44 kW, 1,272 cc, 4-cylinder Inline configuration, 4-speed Manual gearbox, and FWD. The second-generation example is the more clearance-oriented choice at 120 mm, compared with 95 mm for the first generation.
Choose the second-generation 1.3 MT with 1,289 cc and 55 hp if reaching the listed peak torque at the lower engine speed matters more than maximum power. It provides 100 Nm at 2,800 rpm, 400 rpm below the 75 hp version’s torque peak. The trade-off is 20 hp less output and a lower calculated specific output of about 42.7 hp per litre.
The 1.1 MT is the direct middle choice. In either generation it combines 1,093 cc with 50 hp and 37 kW, placing it 10 hp above the 40 hp base engines and 10 hp below the 60 hp 1.3 MT. Its calculated 45.7 hp per litre also sits between the second-generation 1.0 MT at 40 hp per litre and the 1,272 cc 1.3 MT at about 47.2 hp per litre.
For minimum displacement, choose the first-generation 0.9 MT: its 895 cc engine is 105 cc smaller than the second-generation 1.0 MT, yet both produce 40 hp and 29 kW. The 0.9 MT consequently has the stronger calculated output per litre, about 44.7 hp versus 40 hp per litre. The second-generation 1.0 MT counters with 120 mm of ground clearance, 25 mm more than the 0.9 MT’s 95 mm.
There is no evidence here for choosing on acceleration, top speed, mpg, weight, tank capacity, or wheel size because those values are not measured. For a used Volkswagen Derby, the defensible catalogue choice is therefore based on the recorded specification: the 75 hp 1.3 MT for maximum output, the 60 hp 1.3 MT for the strongest Carburetor setup, the 55 hp 1.3 MT for 100 Nm at the lowest measured engine speed, or the second generation generally when its additional 25 mm of ground clearance is preferable.
