    I wonder how that choice will affect front impact safety. The frunk has multiple functions, chief amongst them in my mind is the extra crumple area.

    Or just lazy engineering.

    The Leaf has plenty of air-gaps in the motor bay. More than enough to support a significant crumple area. For a FWD vehicle (which is much easier for novice drivers to handle in the wet and snow), keeping everything under the hood increases your trunk space significantly. Besides, integrating the motor, HVAC, and inverter into your crumple zone (as mass decelerators) is a nice side benefit.

    This is all just an engineering decision to favor understeer versus oversteer, nothing more.

    As the previous owner of a 2016 LEAF I don't recall the motor bay being particularly airy, though there was certainly less mass than an engine block.

    As a former do-all-my-own-maintenance guy, the engine bay is noticeably sparse: Nissan Leaf Guide NZ

    Anyway, the point isn't about the actual amount of space there, only that there's enough to achieve good crumple zone results. So the design choice is really about FWD vs RWD, and their associated trade-offs. Of course, if you cared about servicing the HVAC system, then I would prefer FWD.

    I feel like the numbers are disconnected from reality.

    There's the Model 3 Performance, for which I see 4072 lbs, 450 HP, 472 lb-ft, 3.2 second 0-60.

    Or this E-tron S Sportback, 3 motors, 496bhp and 718 lb-ft, yet 4.5 second 0-62. Extra motor, extra battery, extra horsepower and torque, but 40% less acceleration 0-60(ish).

    Oh, wait. Does that seriously say 5770 lbs? It's a sedan that weighs 42% more than the heaviest Model 3? What the...?

    So this is Audi's grand plan. Announce a performance model, first production car with three electric motors... and then load it down with so much weight that it "competes" with a non-performance Tesla?

    RESEARCH - you have internet search - you don't want to just guess about safety, do you??

    The ariya shares the same wheelbase length as current Maxima and previous Altima, those are long bonnet vehicles, Nissan spent effort to engineer out the frunk, (due to styling message)

    I disagree. I'd say they spent no effort to change the design to create a frunk and just used existing ICE engineering concepts to create an EV drive unit that looks essentially like an ICE unit instead of something more compact. That's what they did with the LEAF.

    Haha, Mercedes thinks Model S LR's range will remain the same for 18 months.

    And what would be the price of the EQS with that range?

    "Further details closer to launch"

    This is the BEV version of S Class.

    S-Class in the US starts at $95k and tops out at $240k.

    thats the difference between creativity and effort. Nissan spent the effort to make the Ariya not look like a Maxima, part of that effort was to cut out the space for the frunk.

    JRP3, if you don't think the Ariya is based on the Maxima, then what Nissan is it based upon?

    The Maxima doesn't have a frunk, it has an ICE that fills the space. The Ariya has an electric motor/inverter that fills the space. What effort was put into eliminating the frunk other than failing to optimize the motor/inverter format? That's a lack of effort.
