This engine cranks out 178 horsepower and 195
lb-ft of torque, and also uses Kia's new continuously variable valve duration
(CVVD) technology. Putting this to use can result in 4 to 5 percent better efficiency,
along with a 12 percent improvement in tailpipe emissions. A variable duration
adjuster moves up and down, and actually shifts the contact point of the cam
lobe. When the duration adjuster is moved determine the duration of time a
valve is open. The predominant benefit is that a long valve duration takes
place during low engine speeds, allowing more time for the air to sufficiently
enter the cylinder.
As Car and Driver reports on the
blog this week, the top of the group GT variant makes 286 horsepower and 311
lb-ft of torque, with much of the credit going to the turbocharged 2.5-liter
inline-four. Speed tests have proven it to go from 0 to 60 in around 6.6
seconds, and there is talk of a hybrid powertrain in the works as well. There
is also a 2.0-liter 4-cylinder engine, a higher-output continuously variable
valve lift version of the identical 2.0-liter. All of these engines come
standard with either a 6 or 8-speed automatic transmission. The updated Optima
features front-wheel drive as standard, and all-wheel drive is expected in the
United States variant as well.
The seasoned staff on duty at Cnet's
Roadshow claimed regarding the 2021 Optima that “if you're staring, you
might want to keep staring because this one's deeply attractive”. Everyone here
at Jim Butler Kia of St Louis is so
excited about the “Tiger Nose Evolution” we have seen with our brand line's
sedan appearance: you know when one is coming up on you, and the looks are
striking as well as modern!
Another very cool element of the 2021 model's
design is the band of chrome outlining the side window line, which looks
attractive combined with frameless doors and blacked-out roof treatment. We
will keep you posted about developments and release dates regarding the Optima
here on the blog and are completely geared up to show you after a test drive
how fantastic and fundamentally useful a brand-new Kia can be for you this New
Year!
