4. Cadillac ELR – MSRP: $65,000 – $65,000
The 2016 Cadillac ELR is powered by a lithium-ion battery, a four-cylinder gas engine and two electric motors. Automotive writers say the ELR’s powertrain is smooth and delivers fairly quick acceleration when driven in full-electric mode. However, they report that when the gas engine is engaged, it is very noisy, especially under hard acceleration.
