Audi Q4 e-tron 45.
The middle Q4 e-tron version with the bigger battery. The most balanced variant.

The Audi Q4 e-tron 45 is the RWD version with the bigger battery, introduced in 2023 between the 40 and 50 quattro variants. The most balanced version of the Q4 - a compromise between price and range.

The 45 is RWD with a 76.6 kWh net battery, 286 hp and a WLTP range of 543 km. The same battery as the 50 quattro, but 1 motor instead of 2 = more range.

Starting price of around PLN 225,000. The competition - BMW iX1, Mercedes EQA, Volvo EX40, Skoda Enyaq 85. The Q4 e-tron 45 is the most popular one.

In Poland, the BEV market is growing steadily - more than 30,000 new EVs were registered in 2024. The Audi Q4 e-tron 45 fits the trend of rising electric car sales. Customers choose this car for the prestige of the Audi brand, economical overnight charging and full access to the clean transport zones in Warsaw, Krakow and other Polish cities. It's a fully fledged BEV with no local emissions.

Why a fully electric car and not a hybrid? Because a BEV means zero refuelling, zero local emissions and zero fuel cost when you charge overnight on the G12 tariff. In the Q4 e-tron 45 you do your daily commute quietly and without jolts. Plus you can drive into clean transport zones (Warsaw, Krakow, Wroclaw) without restrictions. For people who cover 30-60 km a day and head out on longer trips 2-3 times a year, the Q4 e-tron 45 is a fully fledged BEV solution.

Before we get into amps and kilowatts, we need to establish which box the Audi Q4 e-tron 45 falls into. The four drivetrain types on the European market in 2024-2025:

Before we get into amps and kilowatts, we need to establish which box the Audi Q4 e-tron 45 falls into. The four drivetrain types on the European market in 2024-2025:

MHEV (48 V mild hybrid) - weak assistance for the combustion engine, no EV mode. HEV (full hybrid, e.g. Toyota Prius) - a 1-2 kWh battery that only charges from braking. PHEV (plug-in hybrid, e.g. BMW 330e, Lexus RX 450h+) - a 12-25 kWh battery, real-world EV range of 50-90 km, Type 2 port. BEV - that's our Audi Q4 e-tron 45: a full EV, no petrol engine, 100% electric.

Audi's decision to go pure BEV in this segment was deliberate. CO2 rules in the European Union force zero fleet emissions by 2035, and customers increasingly choose charging locally over filling up at a station. Audi is investing in developing fully fledged BEVs - the Audi Q4 e-tron 45 is an example of that strategy.

Manufacturers today fall into two schools: those who build BEVs on a modernised combustion platform and those who use a dedicated BEV platform (e.g. Hyundai E-GMP, VW MEB, Mercedes EVA). Each strategy has its upsides: a modernised platform gives familiar handling and lower production costs, a dedicated one gives better efficiency and more room inside. The Audi Q4 e-tron 45 uses the optimal configuration for its segment.

The Q4 e-tron 45 pack is built with lithium-ion cells supplied by LG Energy Solution from its plant in Poland (Wroclaw). The manufacturer uses liquid cooling and BMS thermal management.

Why is the capacity buffer so important? Because Li-ion cells age fastest when they're charged to 100% or discharged to 0%. Most manufacturers hide 5-10% of capacity at both ends of the scale. That gives 1,500-2,500 charge cycles without significant degradation. If you plug in every day, that's 7-10 years of running a Q4 e-tron 45 without losing significant capacity.

Check the production year of your Q4 e-tron 45. The manufacturer regularly introduces improvements - better cells, heat pumps, thermal management software. Real-world measurements from owners of BEVs from 2020-2022 show 8-12% degradation after 5 years, while newer cars (2023+) are projected at 4-6% over the same period - a better BMS and modern cell chemistry.

The battery mounted under the floor of the Q4 e-tron 45 preserves a practical boot and gives a low centre of gravity - key to driving dynamics. The Audi Q4 e-tron 45 makes use of this layout while keeping its interior versatile.

Under the floor of the Q4 e-tron 45 sits a permanent magnet synchronous electric motor (PMSM) or an asynchronous one (in AWD versions). System power and torque deliver an instant response to the accelerator - a characteristic BEV trait that makes even the weaker variants feel "faster" than comparable combustion cars.

The Audi Q4 e-tron 45 offers the standard driving modes: Comfort (default, balanced), Eco (energy saving) and Sport (maximum performance). Real-world energy consumption in the combined cycle: 16-20 kWh/100 km in summer, 22-26 kWh/100 km in winter (cabin heating draws as much as 5 kW from the battery). Intelligent regenerative braking feeds braking energy back into the battery.

The manufacturer, Audi, deliberately limited the Q4 e-tron 45's AC charging power to 11 kW. The logic: plug in in the evening, unplug in the morning - 6-8 hours is more than enough for most customers. Investing in a more powerful OBC (On-Board Charger) would raise the car's price by several thousand with no real gain in a typical usage scenario.

What is the onboard charger, or OBC (On-Board Charger)? It's a device built into the car that converts alternating current from the wall into direct current for the battery. In the Q4 e-tron 45 it's a three-phase 16 A 400 V unit, 11 kW in total. CCS Combo 2 connector (the European standard). DC charging goes through the fast-charging port - at public stations at up to 150-250 kW (depending on the model version).

Many customers ask whether the Q4 e-tron 45 can be charged at a higher AC power from a home wallbox. The answer is no. The manufacturer, Audi, has never offered an OBC bigger than 11 kW for this model. It's a cost decision: a more powerful OBC adds EUR 400-600 to the price of the car, and with a typical battery the difference in charging time is an hour or two instead of the overnight window in which the car sits in the garage from evening to morning anyway.

Let's pause at the most common sales myth. Dealers suggest that the fastest home charging is a fixed wallbox. That's a half-truth. A wallbox is simply a charger in a wall-mounted housing. From the Q4 e-tron 45's point of view there's no difference between an 11 kW wallbox and an 11 kW portable charger plugged into a CEE socket. The charging parameters are identical. The portable charger has one advantage: you can take it to a hotel in Masuria, to your in-laws' summer house, on a road trip to Italy. The wallbox stays on the wall.

The Audi Q4 e-tron 45 doesn't exist in a vacuum. The premium compact BEV SUV segment is a fight between several players.

When does the Audi Q4 e-tron 45 win? Brand character - handling, quality of finish, the Audi dealer network. Every manufacturer has its own DNA: BMW - sportiness, Mercedes - luxury, Volvo - safety, Hyundai/Kia - value for money, French brands - design. When does the Q4 e-tron 45 lose? Here you need to weigh up the alternatives - range, DC charging, price. The best thing is to compare it with the competition in person, on a test drive at the dealership.

And how does it compare with more expensive models? Most brands have a BEV ladder: compact, mid-size, flagship. Each step up brings a higher price and more performance. The Audi Q4 e-tron 45 positions itself as the optimal choice in its segment - if you mostly cover short and medium distances, have a garage with charging and aren't afraid of public fast chargers on the road, this model will be a sound choice for years.

The Audi Q4 e-tron 45 has been through dozens of tests in Polish and European motoring media. The consensus is clear: good handling and performance for the segment, economical running. The weaker points usually remain motorway range (a 25-30% drop at 130 km/h) and DC charging at public stations (the curve drops off after a 50% charge). Below is a summary of the main findings from independent tests.

According to industry tests by the motoring press, the real-world range of the Q4 e-tron 45 falls within 80-95% of the declared WLTP figure in the combined cycle. In summer, with gentle city driving, you can reach as much as 105% of WLTP, while in winter it drops to 70-80%. The winter drop has two causes: colder cell chemistry gives up less energy, and cabin heating draws as much as 4-5 kW from the battery. A heat pump (in newer versions) reduces that drop by 30-40 per cent.

Independent road tests highlight the handling: a low centre of gravity (battery under the floor) and a stiff body give the Q4 e-tron 45 better cornering stability than its conventional combustion counterparts. The car retains the characteristic Audi traits - handling, comfort, a quiet cabin. The downside of BEVs in their heavier versions (AWD, big battery) is weight - 2-2.5 tonnes is no sports car, despite the instant torque.

Industry analyses of the EV market indicate that the Audi Q4 e-tron 45 has a deliberately designed DC charging curve - the manufacturer balances speed against battery life. A customer charging overnight at 11 kW AC and occasionally at public DC chargers has every scenario covered - daily commutes and long-distance trips. Independent testers confirm this logic: a typical household gets 85-95% of its energy from overnight AC charging.

That's exactly how we see it at Ampere Point. A customer buying an Audi Q4 e-tron 45 gets from the manufacturer a car deliberately designed for overnight 11 kW AC charging and occasional DC fast charging. Our Q11 and P11 portable chargers are a perfect match for that profile: the full 11 kW, a Type 2 cable, 6-8 hours to a full Q4 e-tron 45 battery. No fixed wallbox installation, no electrician, no cutting into the wall.

The Audi Q4 e-tron 45 is a choice for the informed customer in the premium compact BEV SUV segment. Recommendation: Q11 or P11. Both charge the Q4 e-tron 45 in 6-8 hours.
