PALMS SPRINGS, Calif.—For many years, automakers like BMW and Mercedes-Benz have fought one another in group exams for the title of “world’s greatest automotive,” an honor awarded by varied magazines. The battle has normally been between the 7 Series and the S-Class, with occasional challenges from Lexus. Jaguar and Cadillac typically path behind.
Today, there is a severe new contender for the crown as BMW’s latest era 7 Series goes on sale.
I bought hooked on cars-as-technology throughout the early ’90s, and what a method the vehicles have come since, as powertrains have pushed new limits and vitality sources, and interiors have change into extra cosseting and protecting of their occupants.
The Bavarian OEM made the choice just a few years in the past to put money into a powertrain-agnostic car structure, so the brand new 7 Series will probably be accessible with an inner combustion engine, as a plug-in hybrid (which can come to the US in time), and as a totally battery-electric model known as the i7. BMW introduced each gasoline and BEVs to Palm Springs for the worldwide first drive, and you’ll be able to learn in regards to the 760i xDrive elsewhere on these pages at this time.
But the star of the present is the i7, which but once more proves that if you wish to make a luxurious automotive even higher, give it electrical motors.

The electrical model has full function parity with its petrol-powered companion, together with a brand new superior driver help system that allows you to cruise hands-free on premapped divided-lane highways and an enormous curved theater show for fortunate rear seat passengers. BMW has even managed to make the automotive enjoyable to drive.
The electrical powertrain tech within the i7 is now comparatively acquainted. It’s BMW’s Fifth-generation EV powertrain, and it debuted in final yr’s i4 sedan and iX SUV. It makes use of the identical household of electrically excited synchronous motors for each axles, fed by a lithium-ion battery pack that makes use of prismatic cells. (BMW is switching to cylindrical cells for its sixth-gen EV platform, which we’ll see in 2025’s Neue Klasse.)
There’s only a single i7 on sale for now, the $119,300 i7 xDrive60. The car makes use of a 255 hp (190 kW), 296 lb-ft (401 Nm) entrance motor and a 308 hp (230 kW), 280 lb-ft (380 Nm) rear motor with a mixed whole output of 536 hp (400 kW) and 549 lb-ft (745 Nm). The battery pack has a usable 101.7 kWh out of a complete capability of 105.7 kWh.

The i7 has an official EPA vary estimate of 318 miles (512 km) on the smaller 19-inch wheels and 308 miles (496 km) when clad with 21-inch wheels, as was our take a look at automotive. Over the course of a 2.5-hour drive that featured numerous elevation change and little or no city driving, I averaged 2.7 miles/kWh (23 kWh/100 km), barely higher than the two.6 miles/kWh (23.9 kWh/100km) EPA ranking.
Charging ups and downs
DC fast-charging takes 34 minutes to return the battery to 80 % state of cost (SoC), or 80 miles (129 km) for each 10 minutes, and i7 homeowners will get three years of limitless charging classes at Electrify America. I tried to cost my take a look at i7, however my fast-charging try led to partial success. I arrived on the charger with 56 % SoC remaining, however the session was terminated as a consequence of a fault or error after just some minutes and 9.5 kWh, which took the battery to 67 % SoC.
If I had truly wanted to high the battery as much as 80 %, I’d have unplugged the automotive and plugged it again in to attempt to troubleshoot, however I did not want 80 % and did not really feel like losing half an hour on the telephone to be informed that nobody else is aware of why it occurs, both.

You’ll word I’m within the flawed bay, because the unit I parked in entrance of saved having communication errors with the automotive. What you’ll be able to’t see is that I’m taking the picture from the center of the drive-thru line at In-N-Out, which makes accessing these chargers virtually not possible (and even worse should you drive in and discover your plug is on the flawed facet and also you want flip the automotive by 180 levels).

I bumped into In-N-Out to seize a burger, and whereas I used to be ready, the charging session terminated.
EVgo -
The info right here was not ample for me or the BMW engineers to find out what occurred and whether or not it was the automotive’s fault or the charger’s. Maybe a hen sat on the cable and broke the connection? This shouldn’t be so opaque.
BMW
Upon my return, I let the BMW engineers know in regards to the problem, and once they realized I used to be utilizing an EVgo charger, they gave a figuring out nod and mentioned sure, that they had been experiencing issues with that financial institution all month. (BMW introduced in waves of worldwide media over a number of weeks to drive the i7; Ars and the opposite US and Canadian shops have been the final of these.) Beyond that, they did not know what the issue was, which simply reinforces my argument about fast-charger reliability from earlier this summer time.
