    [​IMG] Despite slow sales, thankfully the Sonata Hybrid was not canceled and should be even better than ever before!

    Wayne Gerdes – CleanMPG – July 21, 2019


    Hyundai released details on their all-new Sonata hybrid transmission that not only indicated that the 2020 Sonata Hybrid will not only be made available, it will incorporate the worlds first Active Shift Control (ASC) transmission. The upgrade appears to be mostly computer hardware and software in nature while still not incorporating a torque converter as gear shifts are monitored up to 500 times per second to adjust transmission rotation speed for faster shift times. The new technology will premiere in the upcoming Hyundai Sonata Hybrid and eventually benefit other upcoming Hyundai and Kia hybrids.

    ASC applies new control logic software to the Hybrid Control Unit (HCU), which then controls the electric motor to align the rotational speeds of the engine and transmission to reduce gear shift time by 30%. The technology also delivers smoother gear changes despite quicker shift times.

    Independently Developed Control Logic Software Applied to the Electric Motor

    Conventional hybrid vehicles do not have torque converters in order to further improve fuel. Although fuel efficient, such a system also requires longer shift times to ensure smoother gear changes.

    ASC technology allows the hybrid’s electric motor to also take control of gear shifts by applying new software logic to the Hybrid Control Unit (HCU) to mitigate issues with slower shift time. The HCU monitors the rotational speed of transmission with a sensor installed inside the electric motor at 500 times per second to quickly synchronize the rotational speed with that of engine.

    With the synchronization, shift time is reduced by 30% from 500ms to 350ms. This not only improves hybrid vehicle’s acceleration performance and fuel economy, but also durability of the transmission by minimizing friction during gear shift.

    Sonata Hybrid unveiled in South Korea. They write, "The Sonata Hybrid is equipped with a SmartStream G2.0 GDi hybrid engine and a hybrid six-speed automatic transmission, delivering power output of 152 horsepower (ps), maximum torque 19.2 (kgf · m) and 10% Improved fuel economy of 20.1 km / l. (Based on 16 inch tires ※)" And 20.1 km/l translates into just over 47mpg. Interesting numbers.

    Equals about 188 N·m or 139 foot-pounds in legit units.

    And I'm sure that's just the engine, not the electric drive that will boost "system" horsepower and torque into the "typical for the class" range.
    I'm pleased to see that Hyundai isn't playing the horsepower game.
    The 1.6t SmartStream engine is going to be the one offered in the Sonata "turbo", with the 2.5t going into the "N" version. (where N = Nincompoop - a person whose self-worth is calculated by how fast they can get to 60 miles an hour in rush hour traffic)
    The little turbo is going to generate a lower horsepower number than the older high-strung 2.0 motor, but with shorter gearing and the new CVVD variable valve duration, it will feel faster than the old 2.0t.

    That matches the 10% gain mentioned also in the video. So then probably around 46 mpg EPA. Pretty decent improvement and similar to Camry (46 mpg) and close to Accord (48 mpg combined).
    There's also talk about new solar roof: 6 hours of daily sun yields about 800 miles a year according to Hyundai. So about 2 mile for 6 hours of sun I think.
    I don't park my car outside typically for a long time often and 6 hours is a lot of exposure for just 2 mile. But no surprise there as typically they haven't been cost effective yet (e.g. Prius). But ignoring cost it's pretty green at least:).

    I read somewhere that the US DOT doesn't allow full solar roof coverage due to crash standards and safety in a rollover. There's metal under the panels so my guess is that a rollover could expose the panel wiring to moist earth, but who knows. I'm not sure how authentic this is considering the old Fisker had its share of solar cells on the roof so maybe there's some limitation that can be avoided?
    I do like the solar roof idea.

    Glad to see the Sonata Hybrid continuing. It's an amazingly comfortable and quiet ride, while reducing fuel consumption. I don't feel like I gave up much in efficiency, but gained boat loads in creature comfort.

    The Prime's supposedly didn't pass because of the glass covering. It wasn't safety glass, so meant lots of sharp shards when it broke.

    Well, that figures. The Safetyists strike again.

    A film application may have been enough to address the issue, but I don't think enough US buyers were interested in paying for the option to make it worth Toyota's wild; it's $3000 in Japan.

    Toyota said it wasn't available because of safety, but they also said the Prime had 4 seats because of weight concerns, and 5 would need more reinforcing.

    Hi All:

    The 2020 MY Changes from the Hyundai Media site...

    2020 Sonata Hybrid - All New

    The 2020 Hyundai Sonata Hybrid is all new. More information will be provided early next year.

    I know, nothing to see here but I thought it was cute. :)

    You know, I don't think the word tranny is politically correct. How about "alternative power delivery system."

    or "alternative gender". Because we try so hard to be politically correct. :)
