Actual mileage will vary depending on driving conditions, driving habits, elevation changes, weather, accessory usage (lights, climate control), vehicle condition and other factors.

Charge time estimates are based on using a 240-volt charging circuit charging from empty to 100% battery capacity. Level 2 is the fastest way to charge at home, though charging times can vary and are dependent on factors such as the capabilities of the charging circuit, charging equipment and the vehicle’s onboard charger.

Battery capacity Battery capacity

Battery capacity is measured in kilowatt-hours, which is a measure of how much energy is used over time. A 70-kWh battery has more energy capacity than a 50-kWh battery and would result in a longer driving range if all other factors were equal. But more battery capacity doesn’t always mean longer range because of differences in energy consumption from vehicle to vehicle. Battery capacity provided by Chrome Data, a JD Power company.

Cadillac that delivers seamless torque/ride qualit

The 2018 Cadillac CT6 plug-in with 40 miles of battery range and full tank of gas will exceed +500 miles or more than any current EV car. On battery 80-100 mpge is the norm and on longer drives 35 mpg at highway speeds and 40 mpg when the 2.0T engine is fired up in the city. The battery will get me to work to charge there and home with errands and eating out with ease as we have seen over 1,500 miles without gasoline engine firing up. The CT6 wheel base is long so most road irregularities are taken with ease. Though rougher surface steets do transmit through the ridge aluminum and steel chassis. The seat area is comfortable and wide with good thigh support for longer legs. The heated and vented seats can be programmed for everytine the car is started. Though tech features like rear view camera is mostly used in congested setting with limited distance viewing like a regular rear view mirror, the night vision works wonders in highlighting sidewalk walkers while deer silhouettes are highlighted with a flashing display and vibrating seat given plenty of time to slow. The night vision works wonders in thr fog that the human eye cannot see. This 2018 was purchased new in March 2020 for about half off the listed price as nothing could match it technology for the middle $30's price.
