what autonomy on small roads? Auto

On the motorway, on the Paris ring road … the autonomy tests of electric cars sometimes overlook the small national and departmental roads. However, these axes are the only ones to allow the movements of very many motorists. We therefore wanted to know the maximum autonomy of the electric version of the Peugeot e-2008. Was he able to reach the 320 km announced before the failure? The answer is to be read in our essay.

From single to double, the range of an electric car varies greatly depending on the road taken. It is considerably different from the official estimate given in the WLTP combined cycle if driving on the highway at high speed. Conversely, on a congested urban axis, it is easy to pass it. On departmental and small national roads, autonomy should therefore logically respect the announced figure. This is what we tried to find out in a Peugeot e-2008.

The electric version of the SUV has been on the market since early 2020. Thanks to its nominal 50 kWh battery for 46 kWh useful, the Peugeot e-2008 boasts 320 km of autonomy in the WLTP combined cycle. The pack powers an engine with a power of 100 kW (136 hp) for 260 Nm of torque. It can be recharged in 7 hours on a 7.4 kW wallbox or 5 hours with the 11 kW option billed at € 300. On high-speed terminals, the SUV accepts up to 100 kW, or a charge of 0 to 80% in about 30 minutes.

Comfortable on small roads

Initially, our Peugeot e-2008 displayed a battery level of 99%. Despite waiting for over an hour in this state, we were unable to reach 100%. The dashboard announces 270 km of autonomy remaining, far from the announced 320 km. This is normal as the estimate is based on the type of driving of the previous user. We must therefore have confidence to embark on the route we have chosen: a 310 km round trip between Chatou in the west of Paris and Bellême in Orne, exclusively on national and departmental roads.

An ideal trip to test autonomy: the speed limit is never greater than 90 km / h. The numerous crossings of villages at 30 or 50 km / h as well as the sections of road placed at 70 or 80 km / h strongly favor sobriety. The Peugeot e-2008 is also very comfortable in this rural and peri-urban environment. Potholes and rough edges are crossed without too much jerk, the suspensions being quite flexible. On the few sharp bends in the route, the handling was flawless. The battery integrated into the floor contributes to stability by lowering the vehicle’s center of gravity. The engine offers great acceleration thanks to its instantaneous torque. Without being dazzling, it is lively enough to quickly and surely overtake the few exceptional tractors and convoys that line our route.

Dashboard to improve

On board, the comfort is satisfactory despite our size (1.90 m). The elevated driving position allows you to look further than in a city car. This is a significant advantage on small roads, where obstacles occur much more often than on the motorway. The small steering wheel is easy to grip and takes the strain off your arms and shoulders on long journeys. Properly adjusted, it does not obstruct the view of the i-Cockpit dashboard. If its reading is clear and easy, it nevertheless deserves many improvements.

We particularly regret the absence of the display of the percentage of remaining battery. It is indeed necessary to be satisfied with a simple gauge with segments and an indication of range in kilometers to know the battery level. This information is however essential. It is communicated by almost all battery-powered devices (smartphone, computer, mobile charger, etc.), why not on an electric car? On the Peugeot e-2008, it only appears a few seconds when the vehicle is connected to a charging station.

The dashboard also surprises with the volatility and lack of precision of the estimated remaining autonomy. It evolves in steps of 20 kilometers and varies too frequently, upwards or downwards, despite constant driving. For a novice driver, this can generate unnecessary stress and misunderstanding electrical technology. The estimate tends to be pessimistic, even with a full battery, hence the importance of showing the percentage of battery which is stable and more reliable information.

To the right of the dashboard, the infotainment screen makes up for these few shortcomings. Oriented towards the driver, it is wide, of good definition and very responsive. Our phone is easily connected via Android Auto to use our own navigation applications.

More suitable for highway driving, driver aids such as adaptive cruise control and lane keeping assist work quite well on national roads. This is a welcome assistance which however requires remaining vigilant, especially when the ground markings disappear or are degraded.

A reassuring turtle mode

When we got to Bellême, halfway there, the Peugeot e-2008 gives us confidence. According to the gauge, there is a little over 50% of range left after driving 152 km. Average consumption is 15.1 kWh / 100 km for an average speed of around 60 km / h. Without reloading, we turn around to reach our starting point.

The first warning displayed on the dashboard occurs with 26 km of estimated range remaining. A “low battery level” message appears on an orange background for a few seconds. We have driven 270 km so far and making the trip now seems more complicated. There is about 15% left in the battery, we must consider charging on a terminal other than the one at the start. A glance at the Chargemap application reassures us by noting the presence of a large number of charging points nearby.

We finally have to make a stop on a marker 14 short kilometers from the finish. After many warnings, the Peugeot e-2008 is now swapping the range estimate for three horizontal segments. A new alert indicates “critical battery level: reduced performance” accompanied by audible signals repeated very regularly. The SUV considerably restricts its power and acceleration becomes extremely slow. This “turtle mode” however makes it possible to reach the charging point in good conditions on small roads. We were able to drive 80 km / h for about 5 km before we got there. On the motorway, you will have to be very careful and not attempt to overtake or enter this situation.

300 km of real autonomy?

When plugged in, the e-2008 displays “0%” of remaining battery. We consumed a full tank after driving 305 km. The performance is satisfactory, close to the 320 km promised by the WLTP combined cycle. Especially since the average consumption is particularly low: 14.6 kWh / 100 km. The lion’s electric SUV therefore barely passed the symbolic bar of 300 km of real autonomy on small roads. A radius of action largely suitable for the majority of everyday uses. The e-2008 can handle even the biggest rounds of a liberal caregiver before being recharged at night.

While its size makes it less agile in large cities, the SUV is very comfortable in rural areas. Its autonomy is optimal on national and departmental roads. It is also easier to charge outside of cities, as the individual habitat offers easy access to the outlet. While performance is no longer an obstacle, price remains a major obstacle to its adoption. The Peugeot e-2008 starts at € 37,100 excluding the ecological bonus of € 7,000. Even after deducting the bonus, the electric is still € 8,150 more expensive than the cheaper petrol version of the Peugeot 2008.

For heavy riders, however, the difference can be quickly offset by fuel savings. Over a year, a motorist traveling 25,000 km will spend around 2000 € of unleaded 95 (at the current average price), against a little less than 600 € of electricity if he recharges at home, see 500 € if he uses the hours hollow. The calculation therefore deserves to be dug before choosing the engine for your next vehicle.

Assessment of the test

Real autonomy on small roads, which exceeds the threshold of 300 km Driving comfort: raised position, small steering wheel and roominess Correct suspension adjustment Absence of display of the percentage of remaining battery Random indications of the estimated range The price elitist
