One of the things which can most impact real world conditions of that ideal electric car or plug-in hybrid you own is extreme weather conditions. We’ve seen vehicles tested before under very cold climates, and now Cadillac’s forthcoming extended range electric vehicle the 2014 ELR is taking its turn in snowy conditions as well.
Cadillac parent company GM said its engineers last week completed what is called winter weather chassis testing on pre-production ELR models in Michigan’s Upper Peninsula. Over four inches of fresh snow during the testing helped them “validate final specifications on the ELR’s steering, tires, anti-lock brakes, traction control, electronic stability control and Continuous Damping Control suspension that adjusts damping every two milliseconds to maintain optimal control over varying road conditions.”
The ELR, which officially debuted in the 2013 Detroit Auto Show last month, has a range-extending generator powered by gas that is just like the Volt’s. It will reportedly offer a full driving range exceeding 300 miles (480 km). The vehicle will be driven primarily by and electric drivetrain and range-extender 1.4L generator capable of 154 kW (207 hp) of total system power. A 16.5 kWh lithium-ion battery pack located in the ELR supplies power to the electric motor, capable of 295 lb.-ft. of instant torque (400 Nm) and, when running under electric mode only, delivering a GM-estimated range of about 35 miles (56 km).
It is said by GM the ELR’s battery can be charged with a 120V electrical outlet or a dedicated 240V charging station. When using the latter option, it is estimated it can be fully recharged in around 4.5 hours. There’s been no mention yet of EPA-certified driving data, but the new Volt currently gets something around 98 MPGe, so expect it to have good numbers when they are unveiled.
Pricing for the ELR, due out in early 2014, has not been set yet.
