The Cadillac "ELR" is a 2+2 coupe model developed based on the design of the concept car "Converj" announced in 2009, and it adopts Cadillac's first plug-in hybrid as its powertrain.
The interior and exterior are designed in line with Cadillac's "Art & Science" concept, creating a high-quality and refined look.ATSIt also features the next-generation infotainment system "CUE (Cadillac User Experience)," first adopted in the ATS, which allows operation of navigation, audio, and climate control via a touchscreen.
The Cadillac ELR's powertrain is a plug-in hybrid system with a generator engine, already used in the commercially availableChevrolet VoltChevrolet "Volt," and the Opel "Ampera," which is a sibling model to the Volt. Unlike Toyota's plug-in hybrid system, the motor is the main component, and the engine is solely for power generation, not for directly driving the wheels.
GM calls this an "Extended Range Electric Vehicle (EREV)" and has achieved a range of over 300 miles (480 km) through a combination of an electric motor, a rechargeable battery, and a gasoline engine for power generation. The battery is a 16.5 kWh lithium-ion battery pack, T-shaped and positioned along the vehicle's centerline between the front and rear wheels for optimal weight distribution.
The total system output from the electric motor is 154 kW (209 hp), with a maximum electric-only (EV driving) range of approximately 35 miles (56 km) on a full charge.
GM states that this EV driving range covers the daily commute for the majority of North American users. Additionally, the 1.4-liter gasoline engine for extended range generation supports longer drives, such as weekend trips. Unlike pure EVs, there's no need to worry about battery depletion, making it currently the most practical EV in the North American market.
