Toyota is taking the Corolla electric

    Cars that are designed from the ground up to be EVs tend to be much better than trying to shoehorn an EV into an ICE design.

    The new Lexus ES350e, which comes in both hybrid and EV flavors, has been pretty universally panned as a mediocre EV [1]. Lexus anticipates that the vast majority of ES sales will be for the hybrid model, and I expect the same will be true of the Corolla.

    The updated bZ and new bZ Woodland on the other hand, which are built as ground-up EVs on the e-TNGA platform, actually seem pretty decent. And I'm hopeful for the upcoming EV Highlander, too (although that will use a modified version of the TNGA-K platform).

    I would prefer if Toyota just released a new EV model with roughly the same proportions as the Corolla, instead of going with the one-size-fits-all approach. But maybe they'll finally be able to get it right this time.

      I agree that it&#x27;s much better to design an EV to be an EV from the ground up. The reality is, however, that consumers don&#x27;t want EVs for a myriad of reasons and prefer hybrids. And developing two completely different platforms is too expensive even for a higly profitable company like Toyota.

        Current Toyota engines - several years in production already - used in hybrids have 40% thermodynamic efficiency, new Chinese engines (Geely and BYD) - 45% and soon coming out Toyota engine is claimed to hit 50%. With the numbers like this the hybrids ( and plugins, given the falling prices and increasing charge&#x2F;weight density of the batteries) seem to still have a long and profitable path forward.

        Granted it may result in Toyota losing the battle in the long run. On the other hand any large improve in batteries may gradually bring Toyota into EV world just by letting to upsize the plugins&#x27; batteries.

        Personally i like very much my 2015 Prius Plugin, and the only thing i&#x27;d want about it is to have additional 20KWh of batteries (may be one day i&#x27;ll throw them in myself :)

          Very impressive for a combustion engine, but still way worse than the ~90% efficiency of a battery electric car

            If your electricity comes from hydro, solar, wind - yes. If your electricity comes from fossil fuels - best power plant efficiency 60% - then not really. In US fossil fuels generate 60% of all the electricity.

              90% * 60% = 54%, which is still way better than the most efficient internal combustion engines. So even in that case an EV is still better. Plus, it gets greener when the grid gets greener.

                I&#x27;m not super concerned about green energy, but i put solar panels on my roof and charge an ev because it&#x27;s incredibly practical and a much better experience than the status quo.
