The Peugeot iOn, a fully electric city car, was produced between 2009 and 2013. Developed in collaboration with Mitsubishi Motors, the iOn is essentially a rebadged Mitsubishi i-MiEV. It represented Peugeot’s initial foray into the burgeoning electric vehicle market, aimed at environmentally conscious urban drivers. The 16 kWh variant, producing 67 horsepower, was the sole powertrain option available throughout its production run. The iOn falls into the supermini category, competing with vehicles like the Renault Fluence Z.E. and Nissan Leaf, though with a significantly smaller size and range.

Powertrain & Engine Architecture
The Peugeot iOn utilizes a fully electric powertrain, centered around a 16 kWh lithium-ion battery pack. This battery, positioned under the floor of the vehicle, powers a rear-mounted electric motor. The motor produces 67 horsepower at between 2500 and 8800 rpm, and 180 Nm (132.76 lb-ft) of torque available from 0 to 2500 rpm. The motor employs a direct-drive system, meaning there is no traditional gearbox. Power is delivered directly to the rear wheels. The iOn uses a single-speed reduction gear. The battery pack operates at 330 volts. Charging is accomplished via a CHAdeMO port for DC fast charging and a standard household socket for AC charging. Charging times vary significantly depending on the voltage and amperage of the power source, ranging from several hours for a full charge on a standard outlet to approximately 30 minutes for an 80% charge using a fast charger.
Driving Characteristics
The iOn’s driving experience is dictated by its electric powertrain and relatively low power output. Acceleration is modest, taking approximately 15.9 seconds to reach 62 mph. The immediate torque delivery characteristic of electric motors provides brisk acceleration at lower speeds, making it well-suited for city driving. However, performance diminishes noticeably at higher speeds or when climbing hills. The single-speed transmission means there are no gear changes, resulting in a smooth, linear power delivery. The rear-wheel-drive configuration contributes to a slightly different handling feel compared to front-wheel-drive superminis. The iOn’s regenerative braking system helps to recapture energy during deceleration, extending the driving range. The steering is light and easy, further enhancing its maneuverability in urban environments.
Equipment & Trim Levels
The Peugeot iOn was offered with a relatively limited range of trim levels, reflecting its position as an entry-level electric vehicle. Standard equipment typically included air conditioning, electric windows, central locking, and an audio system with USB connectivity. Safety features such as ABS, airbags, and stability control were also standard. Optional extras included a navigation system, parking sensors, and upgraded interior trim. Interior upholstery was typically cloth, with a functional and minimalist dashboard design. The iOn’s interior prioritized practicality and efficiency over luxury.
Chassis & Braking
The iOn’s chassis is designed to minimize weight, a crucial factor in maximizing range for an electric vehicle. It utilizes a McPherson strut suspension setup at the front and a De-Dion axle at the rear. The front brakes are ventilated discs measuring 247 mm, while the rear brakes are drum brakes measuring 203 mm. The use of drum brakes on the rear was a cost-saving measure, and it also contributed to weight reduction. The iOn’s steering is a rack and pinion system with electric power assistance. Tire sizes are 145/65 R15 at the front and 175/55 R15 at the rear.
Market Reception & Comparison
The Peugeot iOn received mixed reviews upon its launch. Critics praised its environmental credentials and suitability for urban driving, but criticized its limited range, slow charging times, and modest performance. Compared to other electric vehicles available at the time, such as the Nissan Leaf and Renault Fluence Z.E., the iOn offered a smaller range and less overall practicality. However, its compact size and relatively affordable price point made it an attractive option for buyers seeking a basic, no-frills electric city car. Fuel economy, expressed as MPGe, was rated at 155, and energy consumption was 13.5 kWh per 100 kilometers.
Legacy
The Peugeot iOn, while not a commercial success in large numbers, played a significant role in introducing electric vehicle technology to a wider audience. It served as a valuable learning experience for Peugeot as it developed its subsequent electric vehicle offerings. On the used car market, the iOn remains an affordable entry point into electric vehicle ownership. However, potential buyers should be aware of the limited range and the potential for battery degradation over time. The iOn’s simple powertrain and relatively straightforward construction make it potentially reliable, but regular battery health checks are essential. The iOn’s legacy lies in its pioneering role as one of the first mass-produced electric vehicles available in Europe.
