Second time's the charm? Cadillac electrifies again with new CT6 plug-in hybrid

After an embarrassingly short run with the ELR, Cadillac tries electrification again with a plug-in hybrid version of its CT6 luxury flagship.

Caddy took everything I liked about the CT6 luxury sedan and gave us a little more at the 2016 LA Auto Show... well, actually, a lot more range and efficiency with the debut of the 2017 Cadillac CT6 plug-in hybrid.

The new plug-in hybrid model follows the short, unsuccessful run of the ELR. Here's hoping the automaker has better luck with this second attempt at electrification.

For the CT6 PHEV, Cadillac has added two 100 horsepower electric motors to its 2.0-liter turbocharged gasoline powertrain in a complicated setup that basically adapts GM's Voltec technology to the CT6's rear-wheel drive configuration. Peak system output is stated at 335 horsepower, slotting the hybrid between the 3.6-liter and the 3.0-liter twin-turbo V6 versions of the CT6. At 432 pound-feet, the hybrid has the most torque of any CT6 model, which should keep things interesting with an estimated zero-to-60 time of 5.2 seconds.

Full electric top speed is stated at 78 mph; that's freeway speed. Top track speed is stated at 150 mph Hopefully, the rear wheel electric variable transmission will also fix the one complaint that I had about the gasoline CT6 models: a slight jerkiness from the 8-speed automatic transmission when coming to a stop.

The PHEV boasts 30 miles of pure electric range thanks to an 18.4 kWh lithium ion battery bank that is juiced via the electric charging port near the rear of the vehicle. Total cruising range has been boosted to 400 miles at an expected 65 mpge fuel economy estimate -- a substantial jump up from the CT6's previous best of 30 highway mpg.

The 2017 Cadillac CT6 plug-in hybrid hits the road in the US in spring 2017 at an MSRP of $75,095 before a $995 destination charge and any electric vehicle tax incentives.
