When the Cadillac CT6 was originally shown in the US back in March, we only saw the standard gasoline models while the plug-in hybrid was shown in Shanghai. Cadillac brought it to the LA Auto Show with some updated information.
First, let's review some information about the CT6 Plug-In.
The Cadillac CT6 Plug-In uses the same type of liquid cooled batteries found in the Chevrolet Volt. It packs the same number of them as well, 192 cells. Unlike the Volt's T-shape battery configuration, the CT6's are stacked on top of each other directly over the rear axle. Naturally, total battery output also matches the Volt at 18.4 kWh of juice. This is more than double the battery capacity of the Mercede-Benz S550 Plug-In hybrid's 8.7 kWh. Cadillac says that recharging the CT6 from empty will take about 5 hours on 240v service depending on ambient temperatures.
The electric drive part of the equation is handled by a new EVT (Electric Variable Transmission). The EVT has two 100 horsepower electric motors which, combined with power from the gasoline engine, channel power through three planetary gear sets via 5-clutches to the rear wheels. All-wheel drive will not be offered. Those of you who remember the details of GM's older 2-Mode hybrid system might recognize this setup and while the new EVT is not an evolution of that design, Cadillac did take lessons from the 2-mode when designing this system.
The gasoline engine is a version of the 2 liter turbo 4-cylinder found in the base model CT6. Cadillac does not quote the output of the gasoline engine independently, stating only the combined system rating of 335 horsepower and 432 lb-ft of torque. Zero to 60 mph is expected to be about 5.3 seconds. Top speed in electric only mode is 75 mph while overall top speed is 150 mph.
Cadillac says that the EPA estimated EV range for the CT6 will be about 30 miles and combined system fuel economy is estimated at 65 MPGe. These are favorable numbers compared to the S550e's EPA estimated ratings of 14 miles in EV mode and 58 MPGe.
Drivers have three drive modes available. Normal and Sport are self-explanatory, while Hold tells the system to save battery power for use later. Like in the Cadillac ELR, the driver will be able to use paddles on the steering wheel to engage regen-on-demand, a sort of hand brake combined with battery recharging.
Pricing for the 2016 Cadillac CT6 gasoline models was released two weeks ago, but pricing for the Plug-In hybrid is not yet available.
The 2016 Cadillac CT6 goes on sale in March 2016 with the Plug-In hybrid going on sale later in the year.
