Cadillac has announced the 2014 ELR will feature a regenerative braking on demand system.
Dubbed "Regen on Demand," the system is activated when the driver lifts their foot off the accelerator and pulls on either of the steering wheel-mounted paddles. Similar to engine braking, the system then slows the vehicle as it recharges the battery but not to a complete stop.
According to ELR chief engineer Chris Thomason, “Pulling back on the paddle to slow down allows the ELR driver to keep their foot close to the throttle, ready to accelerate. It provides a more engaged, satisfying driving experience, and when you consider the added benefit of re-capturing energy, it’s also a smart thing to do.”
The Cadillac ELR is based on the Chevrolet Volt and uses a range-extended powertrain that consists of an electric motor, a 1.4-liter petrol engine and a 16.5 kWh lithium-ion battery. This setup enables the model to top speed of 100 mph (161 km/h) and travel approximately 35 miles (56 km) on electricity alone.
