Indication of real-world range in several situations. Cold weather: 'worst-case' based on -10°C and use of heating. Mild weather: 'best-case' based on 23°C and no use of A/C. For 'Highway' figures a constant speed of 70 mph is assumed. The actual range will depend on speed, style of driving, weather and route conditions.
The 'long distance suitability' is a 5-star rating that indicates how suitable a vehicle is for long trips. The rating is based on the 1-Stop Range: the total distance a vehicle can cover with one charging stop of 15 minutes.
† This can only be achieved using a 3-phase grid connection. The majority of homes and charge points do not have this connection. In practice charge power will often be 7.4 kW, allowing for a charge time of 15 hours and a charge speed of 23 mph.

Home and Destination Charging (0 -> 100%)
Charging is possible by using a regular wall plug or a charging station. Public charging is always done through a charging station. How fast the EV can charge depends on the charging station (EVSE) used and the maximum charging capacity of the EV. The table below shows all possible options for charging the Mercedes-Benz CLA 45 4MATIC+. Each option shows how fast the battery can be charged from empty to full.

Rapid Charging (10 -> 80%)
Rapid charging enables longer journeys by adding as much range as possible in the shortest amount of time. Charging power will decrease significantly after 80% state-of-charge has been reached. A typical rapid charge therefore rarely exceeds 80% SoC. The rapid charge rate of an EV depends on the charger used and the maximum charging power the EV can handle. The table below shows all details for rapid charging the Mercedes-Benz CLA 45 4MATIC+.
Max. Power: maximum power provided by charge point

Long Distance Suitability
How suitable an electric car is for long trips depends not only on the range. How quickly the car can charge plays an almost equally important role. Whether an EV is suitable for long trips depends on the battery capacity, efficiency, and fast charging capability.
To easily compare cars among each other, a benchmark has been established that combines these factors into the total distance a vehicle can cover with one 15-minute charging stop: the '1-Stop Range'. Based on the 1-Stop Range, the 5-star rating is determined. The result of the benchmark is shown in the graph below.
1-Stop Range
+
Based on the driving profile and assumptions below, the 1-Stop Range is determined. The sum of the distance covered in both trip legs is the 1-Stop Range. For vehicles that cannot fast charge, only the distance from the first leg applies.
Driving Profile
Start with a fully charged battery
Drive until 10% battery charge is reached (leg 1)
Fast charge: 15 minutes
Drive until 10% battery charge is reached (leg 2)
Assumptions
Speed, climate, and external conditions based on Real Range Highway
No time required for starting and stopping the charging session
The charger can always supply the charging power requested by the vehicle
The battery is in optimal condition
In practice, it is impossible to exactly meet the driving profile and assumptions. The benchmark is therefore only suitable for comparing vehicles under standardized conditions.
5-Star Rating
+
The 1-Stop Range describes the distance the vehicle can cover with one 15-minute charging stop. To clearly show the impact of temperature, the 1-Stop Range is determined for three weather conditions. These weather conditions are identical to those in the Real Range benchmark. The 1-Stop Range under average conditions determines the number of stars awarded. The star rating provides a quick way to assess whether a car is suitable for long trips compared to other cars.

Star ratings are based on thresholds in kilometers. Mile values shown for reference.
Vehicles with a result between these threshold values receive a rating based on a linear scale. Haalf stars are possible.
Revision of Rating
+
Annual Revision
The technology of electric cars is developing rapidly. To ensure that the rating remains relevant, the threshold values are evaluated annually. These threshold values apply to all vehicles, including used vehicles. This makes it possible to compare each car against each other based on the current state of technology.
1-Stop Range
The underlying 1-Stop Range is not revised annually. The total distance that a specific vehicle can cover with one 15-minute charging stop remains the same. If the vehicle itself receives an update that changes the 1-Stop Range, then this change will also be reflected in the rating.

All about the Mercedes-Benz CLA 45 4MATIC+
Pricing
The Mercedes-Benz CLA 45 4MATIC+ has an On The Road Price (OTR) of £66,750. The OTR Price includes VAT, first year of VED, vehicle first registration fee, number plates and delivery.
Drivetrain and Performance
The Mercedes-Benz CLA 45 4MATIC+ is a full electric vehicle (BEV). The maximum power of the Mercedes-Benz CLA 45 4MATIC+ is 500 kW (671 hp). The maximum torque is 1298 lb-ft. The Mercedes-Benz CLA 45 4MATIC+ is all wheel drive and can accelerate from 0 to 62 miles per hour in 3.0 seconds. The top speed is 168 mph.
Battery and Charging
The battery of the Mercedes-Benz CLA 45 4MATIC+ has an estimated total capacity of 100 kWh. The usable capacity is 94 kWh. An estimated range of about 350 miles is achievable on a fully charged battery. The actual range will however depend on several factors including climate, terrain, use of climate control systems and driving style.
For example: sustaining high speeds in cold weather could result in a range of around 260 mi. However, driving at low speeds in mild weather will increase the range to around 500 mi.
Charging is done using a Type 2 connector and the on-board charger has a maximum power of 11 kW. This charges a fully depleted battery back to full in around 10 hours 15 minutes. However, a 3-phase grid connection is needed to achieve this. The majority of homes and charge points currently do not have this connection. In most cases the maximum charging power will be 7.4 kW, allowing for a charge time of 15 hours and a charge rate of 23 mph. Charging the car using a regular wall plug will take around 48 hours 15 minutes.
Rapid charging is possible through a CCS connection. The maximum rapid charge power is 330 kW. The battery can't be charged continuously at this power. In an average rapid charge session the average charge power will be around 190 kW. This charges the battery from 10% to 80% in around 25 minutes. A rapid charge like this will add about 245 miles of range.
Energy Consumption
The estimated combined (motorway and city) energy consumption of the Mercedes-Benz CLA 45 4MATIC+ is about 269 Wh per mile. By comparison, this energy consumption is the equivalent of a fuel consumption of 151 mpg in a traditional petrol car.
The actual energy consumption will depend on several factors including climate, terrain, use of climate control systems and driving style. For example: sustaining high speeds in cold weather could result in an energy use of around 362 Wh per mile. However, driving at low speeds in mild weather will increase the efficiency to about 188 Wh per mile.
CO2 Emission
The Mercedes-Benz CLA 45 4MATIC+ emits no CO2 during driving. This only includes direct emissions from the vehicle itself. The energy needed to charge the battery might have been (partly) generated by the use of fossil fuels. Vehicles with an internal combustion engine will always emit CO2 during driving. Additionally, CO2 is emitted during the production and transport of fossil fuels.
