V olkswagen offered us for the primary time a primary glimpse of an undisguised prototype of its future electrical automobiles – in a method. The MEB platform (Modular Elektrobaukasten) will underpin the longer term compact and subcompact battery-powered electrical autos of the VW Group, together with the manufacturing variations of the Volkswagen model ideas now we have seen up to now: ID, ID Crozz, ID Vizzion, and ID Buzz.
For many who are acquainted with fashionable battery electrical autos (BEV), nothing radical right here: the battery is underneath the bottom, the mechanical parts are forward of the firewall and management tools is distributed the chassis. Not having to assist an inside combustion energy practice, the MEB platform is characterised by quick overhangs, no transmission / exhaust tunnel and a utility compartment flooring low. In the course of the presentation, Volkswagen touted the advantages of an EV structure devoted to making a BEV for the MQB platform on which the e-Golf relies. Within the first place, it’s ineffective to place batteries and different tools within the nooks and crannies that may go well with them. Volkswagen attributes this primary gasoline to the 125-kilometer vary of the Electrical Golf and, though we’re just a little skeptical, Hyundai runs 258 kilometers from Kona Electrical, which shares its platform with a basic propulsion mannequin. It’s apparent that the SEM has a variety of area for a giant battery. We’ve no cause to doubt VW's estimate of 200 to 300 miles away, and with the speedy progress in battery chemistry, we hope these figures are conservative.
We’ve discovered different attention-grabbing info in regards to the SEM Platform. First, though BEV engines can have their engines virtually wherever engineers need, the MEB-based automobiles will provide both rear-wheel drive or AWD. VW is on the lookout for benefits by way of propulsion efficiency, which we applaud; Nonetheless, we should ask ourselves what would be the destiny of those consumers. Patrons of Snow Belt need an reasonably priced electrical automobile however could also be uncomfortable with the rear-wheel drive. If they need a VW, they must pay for the all-wheel drive system at additional prices. (Or get winter tires, which might make the drive wheels a lot much less problematic.) With a lot flexibility in powertrain placement, we cannot assist however marvel why Volkswagen doesn’t manufacture BEVs both earlier than.
One other curiosity: the rear brakes are drums. We assumed that it was primarily a motion to scale back prices; in spite of everything, fashionable BEVs rely closely on regenerative braking (utilizing the engines as turbines to cost the battery, which creates a drag that slows the automobile), to the purpose that friction brakes are solely an issue. fraction of the work. VW tells us that the drums have a decrease rolling resistance when the brakes are launched. Drive wheels and disc brakes / drum?
What Volkswagen was making an attempt to argue – and what we contemplate to be an important – is that the electrical automobiles promised within the wake of Dieselgate are on observe, and that it’s going to not solid its future on automobiles with a myriad of powertrain choices. The MEB platform exhibits that it approaches electrical autos in the identical method as gasoline or diesel automobiles, creating an structure that may underpin a household of merchandise designed for all budgets and targets. Contemplating that VW is the world's largest automaker, SEM might sign a drastic change within the availability and acceptance of BEVs.
