2021 Kia Sorento engines, other details revealed before Geneva debut

The 2021 Kia Sorento was shown in official photos a few days ago, but we were missing all of the meaty details. Today, Kia has begun the process of parceling this information out, feeding us powertrain information and a few other interesting features of note. In North America, we can expect at least two engine options: a hybrid and a traditional gasoline-only engine. The latter is slated to be ready at launch — itÂ’ll consist of a 2.5-liter turbocharged four-cylinder, matched with an eight-speed dual-clutch automatic transmission. We imagine itÂ’s the same powertrain that we got a taste of in a pre-production Sonata N-Line not too long ago. In the Sorento, output is 277 horsepower and 310 pound-feet of torque. ThatÂ’s the same amount of torque as Hyundai said the Sonata N-Line will have, but itÂ’s down 13 horsepower compared to the semi-performance sedan. The hybrid powertrain, which is confirmed for the North American market, consists of a 1.6-liter turbocharged four-cylinder and single electric motor. Combined output amounts to 227 horsepower and 258 pound-feet of torque. Kia promises low emissions with high levels of performance, and with those power figures, we imagine the Sorento Hybrid wonÂ’t be a total bore to drive. ThatÂ’s it so far as North America powertrain news is concerned for now, but Kia promised more to come — weÂ’re told to expect additional gasoline engine options and “a powerful new plug-in hybrid variant.” Kia teased out a few details about the new platform this Sorento is riding on, too. The wheelbase is 1.4 inches longer than before, but the vehicleÂ’s overall length is only extended by 0.4 inch. Kia claims better packaging strategies will give the Sorento “class-leading cargo space.” The new platform also allows Kia to put the hybridÂ’s battery pack underneath the floor, claiming it has zero impact on passenger or cargo space. There were a few easter eggs at the end of KiaÂ’s release, too. The Sorento will be the first Kia to feature the companyÂ’s new “multi-collision brake system” that automatically applies the brakes when the airbags have been deployed after the initial collision. It also has a new “remote smartphone surround view monitor.” This will allow folks to look at the vehicleÂ’s surroundings on their smartphone through an app, in addition to seeing it in the infotainment screen.

2021 Kia Optima getting two turbo engines, all-wheel drive option

Even before we've had a chance to drive it, the 2021 Kia Optima is proving to be an interesting sedan. For one thing, it might not even be called Optima anymore, with a switch to the Korean-market K5 name rumored. The styling is thoroughly aggressive, too. As for the latest Optima news, it's getting a pair of turbo engines for the United States, and two more drive wheels as an option. Unsurprisingly, the Optima will be available with a turbocharged 1.6-liter inline-four, just like many versions of its cousin, the Hyundai Sonata. It makes 178 horsepower and 195 pound-feet of torque. There's also mention of a naturally aspirated 2.5-liter inline-four with the same 191 horsepower and 181 pound-feet of torque as the Sonata's base engine. Kia doesn't specifically say it will be offered in America, but its presence in the Sonata means it will probably be available. If those engines aren't powerful enough, the Optima will be available with a turbocharged 2.5-liter engine making 286 horsepower and 311 pound-feet of torque. Presumably, this is the same engine that will be in the Sonata N-Line and future Genesis G70. Kia says this engine is good for a 0-62 mph run of 6.6 seconds. The other big news about the Optima, besides the engines, is that it will available with all-wheel drive as an option. The Sonata does not offer it, making it a unique selling point for the Kia. It will join a growing number of sedans with available all-wheel drive including the Toyota Camry, Nissan Altima, and of course the Subaru Legacy. The Ford Fusion is also among this group, but will soon be discontinued. In addition to all-wheel drive, Kia said Optimas will be available with either six- or eight-speed automatic transmissions, though it didn't specify to which engines they would be paired. The same goes for the eight-speed dual-clutch automatic announced, but seeing as the Sonata only has that on the N-Line, it's probably exclusive to the turbo 2.5-liter engine. Pricing isn't available yet for the new Optima. But Kia did say it will go on sale in the first half of 2020. Related Video:    

Kia's Intelligent Manual Transmission — here's how iMT and clutch-by-wire works

When Kia introduced the facelifted Rio for Europe a few weeks ago, the press release briefly touted a clutch-by-wire six-speed manual transmission that would improve gas mileage and reduce CO2 emissions. A new press release provides details on the Intelligent Manual Transmission (iMT), which we find a surprising avenue of innovation designed just for mild hybrids. Traditional and dual-clutch automatic transmissions, thanks in part to more gears and programmed repeatability, already perform better than human drivers shifting for themselves in metrics including gas mileage. Kia's head of powertrain in Europe said the automaker developed the manual just because "European drivers in particular still love changing gear for themselves." With the pressure on budgets and on standard gearboxes even before the current travails, this seems a benevolent gesture. The traditional linkage from clutch pedal to gearbox goes AWOL in the iMT, sensors on the pedal lever controlling clutch actuation electronically. And an iMT-equipped Kia can take over control of the driveline even when the vehicle is in gear. For example, when a driver takes his foot off the accelerator as he approaches a stoplight, the iMT tells the mild hybrid system to turn off the engine, as it disengages the clutch. Normally, many drivers use coasting in gear in this situation as a way to slow the car without pressing the brake pedal. Kia's system has "the open clutch limiting deceleration and allowing the car to make the most of its kinetic energy," which will mean rethinking one of the finer points of transmission use. If the driver presses the accelerator or brake during the coast, the integrated starter-generator (ISG) restarts the engine. Assuming speed hasn't dipped too low for the chosen gear, the iMT engages the clutch and the driver resumes in the gear the Kia was left in. The hybrid system supplies a boost to get engine revs back up to speed in order to avoid bogging. If vehicle speed is too low to avoid bogging in the current gear, the iMT will disengage the clutch so the car effectively restarts in neutral while in gear, and the driver adjusts.
