PALMS SPRINGS, Calif.—For many years, automakers like BMW and Mercedes-Benz have fought one another in group assessments for the title of “world’s finest automotive,” an honor awarded by numerous magazines. The battle has normally been between the 7 Sequence and the S-Class, with occasional challenges from Lexus. Jaguar and Cadillac usually path behind.
Right now, there is a critical new contender for the crown as BMW’s latest era 7 Sequence goes on sale.
I obtained hooked on cars-as-technology throughout the early ’90s, and what a means the automobiles have come since, as powertrains have pushed new limits and vitality sources, and interiors have develop into extra cosseting and protecting of their occupants.
The Bavarian OEM made the choice a couple of years in the past to spend money on a powertrain-agnostic car structure, so the brand new 7 Sequence will likely be out there with an inside combustion engine, as a plug-in hybrid (which can come to the US in time), and as a totally battery-electric model referred to as the i7. BMW introduced each gasoline and BEVs to Palm Springs for the worldwide first drive, and you’ll learn concerning the 760i xDrive elsewhere on these pages immediately.
However 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 characteristic parity with its petrol-powered associate, 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 is BMW’s Fifth-generation EV powertrain, and it debuted in final 12 months’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 check automotive. Over the course of a 2.5-hour drive that featured a variety of 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 score.
Charging ups and downs
DC fast-charging takes 34 minutes to return the battery to 80 p.c 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 check i7, however my fast-charging try led to partial success. I arrived on the charger with 56 p.c SoC remaining, however the session was terminated resulting from a fault or error after only a few minutes and 9.5 kWh, which took the battery to 67 p.c SoC.
If I had really wanted to prime the battery as much as 80 p.c, I would have unplugged the automotive and plugged it again in to attempt to troubleshoot, however I did not want 80 p.c and did not really feel like losing half an hour on the telephone to be advised that nobody else is aware of why it occurs, both.
Upon my return, I let the BMW engineers know concerning the problem, and after they discovered I used to be utilizing an EVgo charger, they gave a figuring out nod and mentioned sure, they’d 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 had been the final of these.) Past that, they did not know what the issue was, which simply reinforces my argument about fast-charger reliability from earlier this summer time.
