Opel Rocks-e: Which Version Should You Buy?
The Opel Rocks-e has two closely related AT versions: the original Coupe introduced in August 2021 and the restyled Coupe introduced in March 2025. Both use an Electro motor producing 8 hp (5 kW), an Automatic gearbox with 1 ratio, and FWD, while both have a top speed of 45 km/h and recorded CO₂ emissions of 0.
The Opel Rocks-e has two closely related AT versions: the original Coupe introduced in August 2021 and the restyled Coupe introduced in March 2025. Both use an Electro motor producing 8 hp (5 kW), an Automatic gearbox with 1 ratio, and FWD, while both have a top speed of 45 km/h and recorded CO₂ emissions of 0. The practical choice comes down to weight and available specifications: the restyled AT is 46 kg lighter and has a stated torque figure of 44 Nm, whereas torque is not measured for the earlier AT.
Opel Rocks-e generations: what changed?
The first generation began production in August 2021 and remains listed without a stop date. It has a Coupe body and one version, named exactly AT. This version produces 8 hp (5 kW), uses Electro power, has an Automatic gearbox with 1 ratio, and drives the front wheels through FWD. Its kerb weight is 471 kg.
The first-generation restyling began in March 2025 and is also listed without a stop date. It remains a Coupe with one version, again named exactly AT. Output is unchanged at 8 hp (5 kW), and the drivetrain remains Electro, Automatic with 1 ratio, and FWD. The restyled version has 44 Nm of torque and a kerb weight of 425 kg.
The measurable difference is therefore 46 kg: the restyled AT is approximately 9.8% lighter than the original AT. Power is identical, so the earlier model carries about 58.9 kg for every horsepower, while the restyled model carries about 53.1 kg per horsepower. Expressed per kilowatt, those figures are 94.2 kg/kW for the original and 85 kg/kW for the restyling. The restyled AT consequently has the better weight-to-power relationship, even though neither its 8 hp output nor its 45 km/h top speed increased.
Opel Rocks-e engine and specs
| Generation and version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 1 generation AT, from August 2021 | 8 hp (5 kW) | not measured | not measured | Electro | not measured | not measured | not measured | Automatic, 1 ratio | FWD |
| 1 generation, restyling AT, from March 2025 | 8 hp (5 kW) | 44 Nm | not measured | Electro | not measured | not measured | not measured | Automatic, 1 ratio | FWD |
The Rocks-e engine choice does not separate the versions by output: each AT has 8 hp (5 kW). Engine displacement, cylinder count, cylinder layout, boost, motor location, and power-delivery rpm are not measured for either version. Power per litre therefore cannot be calculated from the supplied specifications because displacement is not measured.
The restyled AT provides more complete motor data because its torque is listed as 44 Nm. This does not establish a torque increase over the original AT: the earlier version’s torque is not measured, so there is no valid earlier figure to subtract from 44 Nm.
Opel Rocks-e performance, top speed, and economy
| Generation and version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| 1 generation AT, from August 2021 | not measured | 45 km/h | not measured | not measured | not measured | 0 |
| 1 generation, restyling AT, from March 2025 | not measured | 45 km/h | not measured | not measured | not measured | 0 |
There is no top-speed advantage to choosing the restyling: both versions are rated at 45 km/h. Claims concerning an Opel Rocks-e at 80 km/h are not supported by these specifications. Acceleration from 0–100 km/h is not measured for either AT.
City, highway, and combined consumption are also not measured for either version. Battery size and range are not measured, so the supplied data cannot support a range comparison or a calculation of energy economy. Recorded CO₂ emissions are 0 for both versions.
Opel Rocks-e dimensions, size, and weight
| Generation and version | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|
| 1 generation AT, from August 2021 | 471 kg | not measured | not measured | not measured | not measured |
| 1 generation, restyling AT, from March 2025 | 425 kg | not measured | not measured | not measured | not measured |
Kerb weight is the principal documented size-related distinction. At 425 kg, the restyled AT is 46 kg lighter than the 471 kg original AT. Gross weight, ground clearance, tank capacity, wheel sizes, and exterior dimensions are not measured for either version. Consequently, length, width, height, and other Opel Rocks-e dimensions cannot be compared from the available data.
Both versions use Independent, spring suspension at the front and rear. Both also have Disc front brakes and Drum rear brakes, so the supplied chassis specifications provide no reason to prefer one version over the other.
Which Opel Rocks-e version should you buy?
Choose the 1 generation, restyling AT if the decision is based strictly on measurable specifications. It matches the original AT’s 8 hp (5 kW), 45 km/h top speed, Automatic gearbox with 1 ratio, and FWD, but reduces kerb weight from 471 kg to 425 kg. That 46 kg reduction improves the weight-per-horsepower figure from about 58.9 kg/hp to about 53.1 kg/hp. It also comes with a recorded torque specification of 44 Nm.
Choose the 1 generation AT only if factors outside this dataset make it preferable. On the supplied figures, it offers no additional power, no higher top speed, no different gearbox or drive system, and no documented suspension or brake advantage. It is 46 kg heavier, while its torque is not measured.
Price, availability in the USA or UK, new and used listings, battery size, range, reliability, and problems are not provided. It is therefore impossible to say what extra money the restyling costs or whether its 46 kg lower kerb weight justifies a particular price premium. Based only on the recorded specifications, however, the restyled AT is the stronger buy because it preserves the same stated output and speed in a lighter vehicle.
