Fiat 600: Which Version Should You Buy?
The Fiat 600 choice depends primarily on whether you want the lightweight first-generation 1.1 MT, the second-generation 1.2 i AT Hybrid, or the second-generation electric e AT. The 1.1 MT offers 54 hp, a 5-speed Manual gearbox and published combined consumption of 6 l/100 km. The 1.2 i AT raises output to 128 hp, uses a 6-speed Robotic gearbox and reaches 100 km/h in 11 seconds.

The 1.2 i AT raises output to 128 hp, uses a 6-speed Robotic gearbox and reaches 100 km/h in 11 seconds. The e AT is the most powerful version at 156 hp and 260 Nm, with a 1-speed Automatic transmission and 0 g/km CO₂. All three versions are FWD. The key generational change is equally significant: the Fiat 600 moved from a Mini 3-doors body in the first generation to an SUV 5-doors body in the second.
Fiat 600 generations: what changed?
The first-generation Fiat 600 was produced from 2005 to 2010 as a Mini 3-doors. Its sole listed version is the 1.1 MT, so buyers do not have to compare alternative engines or transmissions within this generation. It combines a 1,108 cc Gasoline engine with 54 hp and 88 Nm, a 5-speed Manual gearbox and FWD.
The second-generation Fiat 600 began in 2023 as an SUV 5-doors and has two listed versions: 1.2 i AT and e AT. Both versions began in September 2023, use FWD and have independent spring suspension at both ends. The 1.2 i AT is a Hybrid with a 6-speed Robotic gearbox, while the e AT is Electro with a 1-speed Automatic transmission. This generation therefore changes both the body format and the available powertrain choices.
Fiat 600 engine and transmission specs
| Generation and version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| First generation 1.1 MT | 54 hp / 40 kW | 88 Nm | 1,108 cc | Gasoline, 95 | 4 | Inline | No | 5-speed Manual | FWD |
| Second generation 1.2 i AT | 128 hp / 94 kW | not measured | 1,200 cc | Hybrid, 95 | 3 | Inline | Turbo | 6-speed Robotic | FWD |
| Second generation e AT | 156 hp / 114 kW | 260 Nm | not measured | Electro | not measured | not measured | not measured | 1-speed Automatic | FWD |
The first-generation 1.1 MT has a front, transverse engine with distributed injection (multi-point), 2 valves per cylinder and a compression ratio of 9.6. Its bore and stroke are 70 × 72 mm, and maximum power arrives at 5,000 rpm while maximum torque arrives at 2,750 rpm.
The second-generation 1.2 i AT also has a front, transverse engine, but it uses direct injection (direct), Turbo boost and 4 valves per cylinder. Its 128 hp from 1,200 cc equals about 106.7 hp per litre. The first-generation 1.1 MT produces about 48.7 hp per litre, so the Hybrid provides roughly 58 hp per litre more. Compression ratio, bore and stroke, peak-power rpm and torque figures for the 1.2 i AT are not measured.
The electric e AT has 28 hp more than the 1.2 i AT, an increase of about 21.9%. Compared with the 1.1 MT, it adds 102 hp and produces nearly 2.9 times as much power. Because displacement is not measured for the e AT, a power-per-litre comparison is not available.
Fiat 600 performance, mpg and economy
| Generation and version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption | CO₂ |
|---|---|---|---|---|---|---|
| First generation 1.1 MT | 14.5 sec | 150 km/h | 8.3 l/100 km | 4.7 l/100 km | 6 l/100 km | not measured |
| Second generation 1.2 i AT | 11 sec | not measured | not measured | not measured | not measured | not measured |
| Second generation e AT | not measured | 150 km/h | not measured | not measured | not measured | 0 g/km |
The 1.2 i AT reaches 100 km/h 3.5 seconds sooner than the 1.1 MT, reducing the published acceleration time by about 24.1%. Its top speed and fuel-consumption figures are not measured, however, so the data cannot support a direct economy or maximum-speed comparison with the older car.
The 1.1 MT is the only version with measured city, highway and combined fuel consumption. It uses 8.3 l/100 km in the city, 4.7 l/100 km on the highway and 6 l/100 km combined. City consumption is 3.6 l/100 km higher than highway consumption.
The e AT has a measured top speed of 150 km/h, matching the 1.1 MT, and its CO₂ figure is 0 g/km. Its 0–100 km/h time and energy-consumption figure are not measured. Accordingly, the higher 156 hp output does not by itself prove that it has the quickest measured acceleration.
Fiat 600 dimensions, weight and clearance
| Generation and version | Kerb weight | Gross weight | Weight per horsepower | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|---|
| First generation 1.1 MT | 735 kg | 1,210 kg | about 13.6 kg/hp | 175 mm | 38 l | not measured |
| Second generation 1.2 i AT | not measured | not measured | not measured | not measured | not measured | not measured |
| Second generation e AT | not measured | not measured | not measured | not measured | not measured | not measured |
Only the first-generation 1.1 MT has measured weight, clearance and tank-capacity data. Its 735 kg kerb weight and 54 hp produce a weight-to-power figure of about 13.6 kg/hp. Gross weight is 1,210 kg, a difference of 475 kg from kerb weight. Ground clearance is 175 mm, and the fuel tank holds 38 litres.
Length, width and other exterior dimensions are not measured for any listed version. Wheel sizes are also not measured throughout the range. The available data therefore does not support a Fiat 600 size comparison between the Mini 3-doors and SUV 5-doors generations, even though their body classifications and door counts differ.
Brakes, suspension and version differences
The first-generation 1.1 MT uses independent spring front and rear suspension, Disc front brakes and Drum rear brakes. The second-generation 1.2 i AT and e AT retain independent spring suspension at both ends but use Ventilated disc front brakes and Disc rear brakes.
This means the two current-generation powertrains have the same listed suspension, brake layout and FWD configuration. The meaningful choice between them is therefore concentrated in their propulsion and transmissions: 128 hp, Hybrid power and a 6-speed Robotic gearbox in the 1.2 i AT, versus 156 hp, 260 Nm, Electro power and a 1-speed Automatic transmission in the e AT.
Which Fiat 600 version should you choose?
Choose the first-generation 1.1 MT if your priorities are a Mini 3-doors body, a conventional 5-speed Manual gearbox and the most complete set of measured ownership figures. It is the only version with published fuel consumption, kerb weight, gross weight, ground clearance and tank capacity. Its trade-offs are clear: 54 hp is 74 hp below the 1.2 i AT, and its 14.5-second 0–100 km/h time is 3.5 seconds slower.
Choose the second-generation 1.2 i AT if you want the SUV 5-doors body, Hybrid fuel type and the quickest measured 0–100 km/h result. Its 128 hp represents an increase of about 137% over the 1.1 MT, while its specific output is more than twice as high. The limitation is missing data: torque, top speed, consumption, CO₂, weight, clearance and tank capacity are all not measured.
Choose the second-generation e AT if maximum listed power and torque are the deciding factors. It leads the range with 156 hp and 260 Nm, delivers 28 hp more than the 1.2 i AT, and records 0 g/km CO₂. It also has the SUV 5-doors body, FWD, an Automatic gearbox and four-wheel disc brakes. Its acceleration, energy consumption, weight, clearance and exterior dimensions are not measured, so those points cannot be used to claim an advantage.
There are no price or sale figures in the available data, so it is not possible to calculate what the extra money buys or identify the best-value Fiat 600. On specifications alone, the 1.1 MT is the data-rich manual choice, the 1.2 i AT is the Hybrid with the best measured acceleration, and the e AT is the power and torque leader.
