While AN thinks it's a 1.0- or 1.2-liter three-pot, Motor Trend is more definitive, claiming the new mill is the all-aluminum, turbocharged three that will arrive in the Opel Adam in 2014. In that setting, it will generate 115 horsepower and 122 pound-feet of torque. That's 31 horsepower more than the 1.4-liter, naturally aspirated four-cylinder in the current Volt.
New engines aren't the only change Automotive News thinks is coming to the Volt – a bespoke, lightweight platform will underpin the second-generation model. The hybrid currently shares its bones with the Chevy Cruze and Buick Verano, but a dedicated platform could help the Volt hit its future fuel economy targets.
