What would you say is the perfect engine
for a compact luxury sedan? According to Cadillac and their CT4 engineering
team, the answer is a dual volute 2.7-liter turbocharged gasoline unit. It
produces 310 HP and 474 Nm of torque in the CT4 Premium Luxury and
325 HP and 515 Nm of torque in the CT4-V, and believe it or not, it
was originally developed for the 2019 Chevy Silverado and GMC Sierra too, not
just the CT4.
However, for the Caddy, GM knew some
adjustments were in order, since the CT4 couldn’t just end up being a sports
sedan with “some” truck engine under its hood. With the new 2.7-liter turbo
unit, you get 5 more horsepower and 88 Nm of torque than you
did with Cadillac’s old Northstar V8, which also happened to weigh more by 64 kg. Furthermore, the 2.7T reaches peak torque at only 1,500 rpm in the
Premium Luxury and 1,800 rpm in the CT4-V – keeping you there until 4,000 rpm
with a very gradual drop-off, claims the carmaker.
The engine utilizes something called a
dual volute turbocharger, sending air to both sides of the turbine, spinning it
quicker and more efficiently thanks to a two-stacked chamber design. You can
buy into the Cadillac CT4 range from US$ 32,995, or simply go straight for the
CT4-V at US$ 44,495.
