Of course it is a factor of weight and so on but the Taycan is around the i4 weight while being both larger (dimension wise), more luxurious and having a larger battery all while being an older car. Sure it is more expensive but BMW wants as much here for the i5 M60 as the equivalent Taycan costs so they are comparable which is why I would expect a larger battery and faster charging for the price. The i4 M50 has an okay battery for it‘s price and size, not pack leading by any stretch but okay. But if you go into a larger car size like the i5 and into Taycan territory money wise I would for sure expect something larger than what the i4 has, because the competitors managed to make that (and more) without being significantly heavier (if at all).
Good point. At that price point it makes sense to look at the competition. The i4 is the better value, but if you have to have a business sedan the i5 e40 (U.S. $68,800 base) has more range 295 miles compared to a Taycan with a 93.4 kW battery. The base Taycan battery is 79.2 kW which is smaller than the battery in the i5 and i4 e40/i4 M50. The larger 93.4 kW battery on the Taycan is a $5,780 option in the U.S. If you are building an i5 M60 with options, but want a higher top speed and range isn’t much of an issue for you then the Taycan is the better choice.
I guess I’m circling back to my point about the Neue Klasse. The iX was built from the ground up to be just electric like the Taycan. When this is done it is easier to save on weight and allow for enough space for ~100 kW batteries. The Mercedes EQS has a range of 350 miles, uses a 108.4 kW battery and was built to be only electric. It’s also much more expensive than an i4 e40…
The i7 shares a platform with the gas 7 series, has a 105.7 kW battery and has a range of 318 miles. The iX SUV was designed solely to be electric, has a 111.5 kW battery and has a range of 307 miles. Clearly if you buy a BMW i4 e40 it is the better buy and you still have 301 miles of range. However even with gas and diesel vehicles some people wanted huge limousines like an Audi A8 or BMW 7 series while others wanted an A4 or BMW 3 series/4 series Gran Coupe and still others wanted inefficient SUVs.
