Den vinner inte min designpris men specen verkar helt ok.

The Cadillac Converj’s Voltec electric propulsion system is made up of a 16-kWh, T-shaped battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car.

A thermally managed battery pack contains more than 220 lithium-ion cells that provide the primary power to drive the Converj electrically up to 40 miles without using fuel or producing tailpipe emissions. The battery is integrated into the Converj’s chassis and stores electricity from the grid when the vehicle is plugged in. It takes less than three hours to recharge the battery at 240V, or about eight hours from a 120V outlet.

When the battery’s energy is low, the Converj seamlessly switches to extended-range mode. During this secondary level of operation, electricity needed to power the vehicle is created on-board by a flex-fuel-powered engine that operates much like a home generator to create electricity. The engine-generator ensures a constant supply of power for hundreds of miles until the car is refueled or plugged in to recharge the battery. This extended-range mode eliminates the range anxiety that comes with driving pure electric vehicles that offer no backup power when the battery charge is low.

Whether in electric or extended-range mode, the Converj is propelled all the time by an electric drive unit. It converts electrical energy from the battery or the engine-generator into mechanical energy to drive the front wheels. It also delivers 273 lb.-ft. (370 Nm) of instant torque, for a quick launch, and 120 kW of power. The top speed is 100 mph.

There is no compromise in vehicle performance in either mode of operation. To enhance the ride feel, the Converj also features GM’s Magnetic Ride Control; and for even greater efficiency, energy during braking is captured and stored in the battery.

Ingen höjdare för förbrukningen när batterierna är tömda...

Finns dock bevisligen vissa fördelar med en seriehybrid som ex att man slipper transmission (vikt, friktion, pengar) samt att det möjliggör bruk av alternativa potentiellt effektivare motortyper än dagens förbränningsmotorer. Att den ändå potentiellt inte är lika effektiv som en parallellhybrid då förbränningsmotorn står för all energi spelar kanske inte så stor roll om man kör till 90% på el vilket jag gissar kommer vara fallet med de som köper dessa bilar. För mig personligen skulle det nog handla om mer än 90%.

Med det inte sagt att det inte finns en marknad för parallellhybrider också. Men en parallellhybrid som kan köras endast på el lika långt som ex Chevy Volt och med samma prestanda vid ren eldrift kommer att vara en dyrare konstruktion.
