#Cadillac announced that their first ever 2017 CT6 Plug-In Hybrid model will arrive in the US in the spring of 2017, featuring a driving range of more than 400 miles (643 km).

The automaker first announced their range-topping CT6 PHEV model last year at the Shanghai Auto Show, when it was revealed that its two-motor EVT system, combined with the 2.0-liter turbocharged four-cylinder petrol unit, would produce a total output of 335 HP (250 kW) and 432 lb-ft (586 Nm) of torque.

Each electric motor puts out 100 HP (74.5 kW), and on electric power alone, the CT6 PHEV can run for approximately 30 miles (48 km) - up to a top speed of 78 mph (125 km/h).

It can also hit 60 mph (96 km/h) from a standstill in an estimated 5.2 seconds, similar to its V6-powered competitors, though with twice the full EV range and MPGe (miles per gallon equivalence) figures.

Still, in terms of autonomy, the combination of its efficient turbocharged engine and battery power enables users to drive more than 400 miles (643 km) before recharging, thus helping remove any range anxiety the driver might experience along the way. Its fuel economy figure is estimated to be 65 MPGe, which in EU terms would be around 3.6 liters/100km.

"The CT6 is a technological showcase throughout, and by far the lightest car in its class, making it an ideal platform for electrification," said Cadillac president Johan de Nysschen. "In the CT6, Cadillac presents a new formula for prestige luxury. The advanced Plug-In Hybrid system is a key addition, providing a combination of exceptional fuel economy, crisp acceleration and strong electric-driving range."

While prices in the US will start at $75,095, there will also be a $995 destination freight charge before any applicable electric vehicle tax incentives. The CT6 PHEV will also be offered as its own unique package within the range, as pricing and equipment levels are to be comparable to the existing Premium Luxury version, which is the second-highest spec in the model range.

Among its many on-board features, customers will find several optional technologies as standard, such as Rear Seat infotainment, Enhanced Night Vision and Rear Camera mirror.
