A line drawing and a shadowy image are the latest elements of an information rollout about the new platform-sharing products.

TOYOTA and upmarket spin-off, Lexus, have released additional clues about their first bespoke electric cars, developed off a common platform for potential release next year.

The brands have each released shadowy images giving a hint of how the Toyota BZ - for ‘beyond zero’ – series and the as-yet-unnamed Lexus will look on release, with industry experts immediately seeing some styling connection between the latter and the LF-30, a concept Lexus displayed at the 2019 Tokyo motor show.

Toyota’s been slow to join the electric car field and for a long time was historically disparaging of the technology, saying it was an unnecessary stop on the journey between the mild-hybrid (so, non-mains replenishable) tech that kicked off with the first Pruis and now proliferates its family and is Kiwi-favoured, to the ultimate future of hydrogen fuel cell motivation.

However, that sentiment ceased when new boss Akio Toyoda took the reins; these brands now have more plug-in hybrid cars – which do rate as EVs – and also have developed the NX300e, a fully battery-reliant version of the smallest Lexus crossover, coming on sale in New Zealand next year.

The latest announcement from Toyota overnight represents further confirmation of a bigger investment into battery driving.

Even though the platform they build upon appears related to the new TNGA underpinning now used by many popular Toyotas, these are not conversions of existing products but new cars designed from the get-go to only be compelled by batteries. In short, they’re bespoke.

Overseas’ reports suggest the BZ series and Lexus are timed to make their public emergences at a common time, but no-one yet quite knows when that will be.

However, 2021 is looking good. Toyota says that it will announce final details on the BZ “in the coming months” and that the model “has already been developed and is being readied for production”.

Toyota New Zealand’s boss Neeraj Lala, in an interview in June on his first day as chief executive, promised “we’ll have an EV here within the next 18 to 24 months. Just in time for demand.”

He would not be drawn into saying which badge that tech would sit behind. In hindsight, it’d surely have to be both.

the LF-30 concept was revealed last year.

A strong styling feature of the Lexus concept is an aggressive bonnet lip over what seems to be a typically complex ‘spindle’ front grille.

The BZ, meantime, is are expected to roughly the same size as the RAV4 SUV - although the wheelbase is almost certainly likely to be longer than that of the conventionally-powered vehicle, and the front and rear overhangs should be shorter.

There’s another string to the BZ bow in that it is likely to also be the basis for an electric Subaru; the brands are, of course, partners already with the current and new 86/BRZ – only the latter coming to NZ, next year, as the GR86 (because it’ll be part of the Gazoo Racing tribe).

Onlookers say panel creases highlighted in the BZ sketch make it clear that it and Subaru’s effort, which has been spoken of in the past, are going to share more than their underpinnings.

Says Britain’s AutoExpress: “The lines should translate into a distinctive-looking model with an image unlike anything else in the Toyota range - much as the Prius hybrids have their own identity.”

Toyota calls its new EV platform e-TNGA, and says it is designed to support a wide range of vehicles, since only a few areas of the architecture - notably the space between the front axle and the base of the windscreen - are fixed.

Toyota claims this allows difference widths, lengths, wheelbases and heights - and also says e-TNGA can be fitted with front-, rear- or four-wheel drive, and a range of battery and electric motor capacities. Some of the trademarks registered by Toyota - including BZ4X and BZ5X - would sit easily on a four-wheel-drive vehicle.

Lexus is reportedly hoping that its defined styling and a sophisticated new four-wheel drive system, called DIRECT4, will lend enough distinction between its model and the Toyotas.

The new Lexus set-up uses a motor on each axle and features sophisticated computer hardware and software that can split power and torque depending on the dynamic experience required.

As all this unfolds, Toyota has also stated intention to build another conventional – so petrol and petrol hybrid – SUV to slot between the C-HR and the RAV4.
