The Norwegian Automobile Association (Norges Automobil-Forbund or NAF) conducted a range test of a series of electric cars in summer and winter conditions to see how far they can drive in a single charge.
Among the cars tested this year is the Citroen e-C4 or Citroen C4 electric which has a 350 km WLTP range.
How the range test was performed by NAF
The test, performed in summer and winter, is an indication of how the cars deliver in relation to the specified range (WLTP) and was run by ordinary drivers in normal traffic. Test routes are the same for both seasons and consist of city driving, country roads, and motorways, at speeds between 60 km/h and 110 km/h. The cars drive through Oslo towards Gjøvik, and drove over Lygnasæter, with a climb of 620 meters before continuing north towards Dombås.
The cars with the longest range continued over Hjerkinn and Folldalog down to Ringebu. Drivers are instructed to follow the traffic and speed and drive normally, but defensively – i.e. no unnecessary overtaking. Regeneration is actively used while driving.
All cars are charged to 100 percent overnight in a garage and are started cold, ie no preheating of either the passenger compartment or the battery, and run in eco mode or equivalent. In winter, the air conditioning is set at 21 degrees and the seat heater is at the lowest level. On the summer run, the air conditioner is at 20 degrees and the fan at the lowest setting.
Citroen e-C4 (C4 electric) range test
NAF was able to eke out 345 km in the summer test (5 km lower than the WLTP rating). However, during the winter test, the car travelled only 261 km, a drop of over 25 per cent over the WLTP range.
NAF says the Citroen electric car tested was equipped with 195/60-18 tires and has a WLTP consumption of 14.3 kWh/100 km. In addition, the summer test was run under optimal conditions with a temperature between 20 and 25 degrees and calm winds, and the car’s consumption was 13.1 kWh/100 km on average for the entire trip.
The Citroen e-C4 drove 345 km in the summer test, 5 km shorter than the stated WLTP range. When the car had 10 per cent battery capacity left, it had driven 332 km. In this test, the car was driven about 13 km after 0 per cent battery left. When it was 28 km range again, a warning indicated that the battery level was low. This warning was repeated at 22 km, 18 km, and 12.4 km range again. When the car finally stopped, a message appeared with a red warning triangle and a fault in the battery system, NAF notes.
The winter test was conducted on the e-C4 Shine variant equipped with Michelin Alpine 6 195 /60 R-18 tires. The WLTP range of the e-C4 was 337 km (this was a pre-production car with a shorter range than later customer cars, notes). The winter test was run in March, with temperatures between 7 and -2 degrees on dry roads. The e-C4 was tested in eco mode with regeneration used actively.
When starting up in the parking garage at Vulkan in Oslo, the car had a stated range of 334 km at 100%. NAF drove a total of 261 km with an average consumption of 16.3 kWh/100km. The first warning of low current came at 16 km left. When the battery indicator was at zero, the car was very slowly and gradually drained of power until it stopped completely, NAF reports.
Citroen e-C4 1000 km challenge by Bjørn Nyland
Norwegian YouTuber, Bjørn Nyland, recently range tested the e-C4 travelling 1,000 km over 11 hours and 15 minutes. The test started with the car at full charge and Nyland stopped eight times to charge the first of which was after 160 km and then each one after approximately 100 km (62 miles). Nyland averaged a speed of 88.9 km/h and recorded an average efficiency of 227 Wh/km.
On the Citroen e-C4
Launched last October, the Citroen e-C4, along with its ICE-sibling, Citroen C4, is its carmaker’s attempt to “put compact hatchbacks back on the map”. The new C4 range has replaced the C4 Cactus and is targeted at those looking for virtues of both conventional hatchbacks and SUVs in the same car. Note-worthily, the C4 is the first family hatchback in PSA Group’s portfolio to offer a zero-emission version in the form of the e-C4.
The Citroen C4 electric sits on the PSA Group’s Common Modular Platform (CMP) that underpins the Vauxhall Corsa, Peugeot 208, and 2008 and their electric versions. The company says that the C4 focuses firmly on the C-segment hatchback market and is a characterful and modern concept, enough to shake up the segment.
The design of the grille of the Citroen e-C4 is in line with the carmaker’s latest styling theme that was first seen on the C3. The front façade carries V-shaped DRLs and chrome chevrons running across the width of the fascia. The lower half of the front bumper sports matte black plastic to add a touch of ruggedness, while the air dam grille carries the chevron pattern from the Ami One concept. The black cladding can be found even on the wheel arches to further add to the SUV-like styling.
The sloping roofline, as per the carmaker, aids aerodynamics, while the rear-end carries stylish V-shaped tail lights along with similar plastic cladding on the lower-half of the bumper.
Citroen e-C4 Interior
Citroen states that the e-C4’s high ground clearance (156mm), together with the short overhangs, helps the driver with a higher vantage point and excellent all-round visibility. Moreover, in line with the brand’s high focus on comfort, the e-C4 comes with Progressive Hydraulic Cushion suspension that makes use of two hydraulic stops to ensure a smooth ride. The e-C4 even offers Advanced Comfort seats along with optional heating and massaging systems.
The dashboard carries a 10-inch touchscreen infotainment unit and a coloured head-up display to complement the all-digital instrument console. The infotainment unit offers Android Auto and Apple CarPlay compatibility and comes mated to a full HD camera that can shoot photos and videos. The C4’s safety suite includes driver assistance features like Highway Driving Assist and Lane Keep Assist.
The Citroen e-C4 is powered by a 136 hp/100 kW & 260 Nm electric motor that draws juice from a 50 kWh battery. The electric car has a driving range of 217 miles/350 km (in WLTP cycle) and is claimed to be capable of sprinting from 0-62 mph in 9.7 seconds. The car comes equipped with Kinetic Energy Recovery System that replenishes the battery under deceleration and braking. It offers three driving modes – Eco, Normal and Sport – to enable the user to choose the right mix of power and energy consumption based on his usage.
The e-C4 comes with an 11 kW charger that can totally charge the battery in roughly 5 hours through a 32-amp home wall-box. There’s even a 100 kW fast charger that can offer 80% charge in 30 minutes on a DC fast charger.
Citroen is planning to electrify its complete range by 2025 and had earlier announced the launch of 6 electrified models in 2020.
