Toyota Prius Alpha: Which Version Should You Buy?
The Toyota Prius Alpha has one core version in the supplied catalogue data: 1.8 CVT, offered throughout the first generation. Cars produced from May 2011 through October 2014 belong to the original model, while those produced from November 2014 through March 2021 are the restyled version. Both use the same 1,797 cc Hybrid engine, produce 99 hp and 142 Nm, and combine a Variable gearbox with FWD.
The Toyota Prius Alpha has one core version in the supplied catalogue data: 1.8 CVT, offered throughout the first generation. Cars produced from May 2011 through October 2014 belong to the original model, while those produced from November 2014 through March 2021 are the restyled version. Both use the same 1,797 cc Hybrid engine, produce 99 hp and 142 Nm, and combine a Variable gearbox with FWD. The meaningful numerical difference is weight: the original 1.8 CVT has a kerb weight of 1,480 kg, whereas the restyled 1.8 CVT weighs 1,380 kg. Based strictly on these specifications, the restyled car provides the stronger power-to-weight result without changing the listed engine output, acceleration, maximum speed, ground clearance, gross weight, or fuel-tank capacity.
Toyota Prius Alpha generations: original or restyled?
The first-generation Toyota Prius Alpha was sold in its original form from May 2011 to October 2014. It was an Estate 5-door with one listed version, 1.8 CVT. This version has a kerb weight of 1,480 kg and a gross weight of 1,865 kg. Its ground clearance is 145 mm, and its fuel tank holds 45 litres.
The same first generation continued in restyled form from November 2014 to March 2021. It remained an Estate 5-door and again had one listed version, 1.8 CVT. The restyled version has a 1,380 kg kerb weight, a 1,865 kg gross weight, 145 mm of ground clearance, and a 45-litre fuel tank. Its listed environmental classification is Euro 5; the corresponding figure for the original version is not measured.
The restyling therefore does not represent another generation. The catalogue contains one generation in two production phases, even though it contains two generation records. It also provides no numerical change in engine output or performance after the restyling. The clear difference is the 100 kg reduction in kerb weight, equal to approximately 6.8% of the original car’s 1,480 kg kerb weight.
Toyota Prius Alpha engine and specs comparison
Both 1.8 CVT versions use the same listed engine specification. The power unit is a 1,797 cc Hybrid with 4 Inline cylinders and 4 valves per cylinder. It has no boost, uses Distributed injection (multi-point), and is installed Front, transverse. Maximum output is 99 hp, or 73 kW, at 5,200 rpm, while maximum torque is 142 Nm at 4,000 rpm. The compression ratio is 13, and the bore and stroke are 80.5 × 88.3 mm.
| Production phase and exact version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| May 2011–October 2014 1.8 CVT | 99 hp at 5,200 rpm | 142 Nm at 4,000 rpm | 1,797 cc | 95 | 4 | Inline | No | Variable | FWD |
| November 2014–March 2021 restyled 1.8 CVT | 99 hp at 5,200 rpm | 142 Nm at 4,000 rpm | 1,797 cc | 95 | 4 | Inline | No | Variable | FWD |
The engine develops approximately 55.1 hp per litre and 79.0 Nm per litre in either production phase. Because displacement, power, and torque are identical, engine output alone provides no reason to choose the original 1.8 CVT over the restyled 1.8 CVT, or vice versa.
The data does not specify engine-oil grade, engine-oil capacity, air-filter details, or replacement-engine information. Those values are not measured here and should not be inferred from the 1,797 cc engine size.
Toyota Prius Alpha horsepower and weight comparison
Weight creates the principal specification difference between the two cars. The original 1.8 CVT weighs 1,480 kg and carries 99 hp, giving approximately 14.95 kg per horsepower. The restyled 1.8 CVT weighs 1,380 kg with the same 99 hp, improving that figure to approximately 13.94 kg per horsepower.
Expressed another way, the original version has approximately 66.9 hp per tonne of kerb weight, while the restyled version has approximately 71.7 hp per tonne. The restyled car consequently offers about 7.2% more horsepower per tonne, although its engine does not produce any additional horsepower.
Both versions have a gross weight of 1,865 kg. The arithmetic difference between gross and kerb weight is therefore 385 kg for the original 1.8 CVT and 485 kg for the restyled 1.8 CVT. These are calculated differences between the supplied weight figures, not stated payload ratings.
Performance, mpg, and fuel economy
There is no acceleration advantage in the supplied figures. Both the original and restyled 1.8 CVT accelerate from 0 to 100 km/h in 11.3 seconds and have a maximum speed of 165 km/h. The restyled car’s lower kerb weight therefore improves its calculated power-to-weight ratio, but the listed 0–100 km/h time remains unchanged.
| Production phase and exact version | 0–100 km/h | Maximum speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| May 2011–October 2014 1.8 CVT | 11.3 seconds | 165 km/h | not measured | not measured | not measured | not measured |
| November 2014–March 2021 restyled 1.8 CVT | 11.3 seconds | 165 km/h | not measured | not measured | not measured | not measured |
No city, highway, or combined fuel-consumption figure is supplied for either 1.8 CVT, so Toyota Prius Alpha mpg cannot be compared from this data. Fuel range is also not measured. Both versions have the same 45-litre tank, but a range estimate would require a consumption figure that is absent.
Toyota Prius Alpha dimensions, weight, and chassis specs
Exterior length, width, height, and wheelbase are not measured for either version. Wheel sizes are also not measured. The available dimensional figure is ground clearance: both the original and restyled 1.8 CVT provide 145 mm.
| Production phase and exact version | Kerb weight | Gross weight | Ground clearance | Fuel tank | Wheel sizes |
|---|---|---|---|---|---|
| May 2011–October 2014 1.8 CVT | 1,480 kg | 1,865 kg | 145 mm | 45 litres | not measured |
| November 2014–March 2021 restyled 1.8 CVT | 1,380 kg | 1,865 kg | 145 mm | 45 litres | not measured |
The suspension and brake specifications are identical. Each 1.8 CVT has Independent, spring front suspension and Semi-independent, torsion rear suspension. Braking is handled by Ventilated disc front brakes and Disc rear brakes.
Seating capacity is not measured in the supplied catalogue data. Searches for a Toyota Prius Alpha 7 seater or Toyota Prius Alpha hybrid 7 seater therefore cannot be answered from these specifications, and seating configuration should be checked separately for an individual car.
Which Toyota Prius Alpha version should you buy?
On specifications alone, the November 2014–March 2021 restyled 1.8 CVT is the stronger choice. It is 100 kg lighter than the original 1.8 CVT, reducing the weight carried by each horsepower from approximately 14.95 kg to 13.94 kg. It also has a stated Euro 5 classification, whereas the original version’s environmental class is not measured.
Choose the May 2011–October 2014 1.8 CVT only if factors outside this dataset make a particular car more suitable. Its listed mechanical output is not weaker: it still provides 99 hp, 142 Nm, an 11.3-second 0–100 km/h time, and a 165 km/h maximum speed. It also matches the restyled version’s 145 mm ground clearance, 45-litre tank, 1,865 kg gross weight, Variable gearbox, and FWD.
No price data is supplied, so there is no supported answer to what extra money buys, nor can prices in Pakistan, Bangladesh, Sri Lanka, or New Zealand be compared. Reliability records, common problems, maintenance history, equipment levels, and condition are also not measured. Within the numbers available, the restyled 1.8 CVT wins because it delivers the same listed engine and performance figures with 100 kg less kerb weight.
