BMW bumps battery for the better: The 2027 i7 60 xDrive, driven
BMW has updated its flagship sedan with the newest EV and infotainment tech.
When BMW debuted the new 7 Series in 2022, it set a new standard for large luxury sedans, increasingly irrelevant though that class is. Rather than siloing off an electric alternative like Mercedes, with its EQS alongside the normal S-Class, BMW simply made the powertrain an option. Stick with a V8 if you want, or consider the rather good electric version instead—only subtle differences like the badging and lack of exhaust pipes give the game away.
Since then, BMW has brought out a string of even newer electric vehicles for the 5 and 3 Series (plus their SUV counterparts). It has switched from battery packs made of prismatic cells to more energy-dense arrangements of cylindrical cells. The motors are still electrically excited synchronous ones, but now the drive units feature silicon carbide inverters and more compact packaging.
This sixth-generation electric powertrain was designed for the clean-sheet Neue Klasse family, which also threw out the legacy cruft of dozens and dozens of discrete single-function electronic control units for a handful of powerful domain controllers. These computers take over those functions but with much faster processing power—and therefore more capabilities in terms of chassis control or powertrain efficiency—as well as the ability to be more easily updated.
Which could have left BMW with something of a problem—should the flagship be clearly outclassed in terms of power and energy density and range efficiency by, well, all the other EVs in the range? Clearly, the board decided the answer to that was no, and for the 7 Series’ midlife update, the i7 got some comprehensive surgery under the skin.
Compared to the last i7 I drove, the 2027 model boasts a higher-capacity battery pack, now 112.5 kWh (net) up from 101.7 kWh, although BMW stuck with a 400 V architecture, unlike in the Neue Klasse or the iX5 we recently drove. A less-powerful 50 xDrive and a more powerful M70 xDrive will also be available, but at the first drive, I sampled the midrange 60 xDrive model, which features a combined 544 hp (400 KW) and 549 lb-ft (745 Nm), roughly equivalent to the pre-facelift car.
Despite that power and torque, the i7 60 doesn’t feel fast like a Porsche Taycan might, and you won’t want to hustle it down a mountain road the way you might the Porsche. The entire driving experience is waftier than that, with the car offering more of a magic carpet ride, a la the iX SUV or even that very fancy cousin of the i7, the Rolls-Royce Spectre.
Even with launch control, 0–60 mph takes 4.6 seconds. Once upon a time, this would have been considered excellent—the V12 750i of the mid-1990s needed at least two seconds more to do that job. But 30 years later, electric sedans from Lucid and Tesla and Porsche and a whole load of Chinese automakers will get you there in less than half the i7’s time, should you want that. If you’re looking for an outright speed machine that will rearrange your internal organs under acceleration, look elsewhere.
In fact, the i7 was remarkably relaxed; even with the traction and stability control turned down, it refused to chirp a wheel or even threaten to break loose in the dry at speeds considered acceptable on the road. But drive it in a more relaxed manner, and it rewards. The steering is precise, and it coasts beautifully on flat or downhill grades, a consequence of those EESMs that offer no resistance to the road when they’re not receiving a charge. The same very smooth regenerative braking to a stop that we experienced in the iX3 and iX5 shows up in the i7, too.
First drive events are never a good way to determine range efficiency, but BMW says between 344—362 miles depending on wheel size. With only a 400 V pack, DC fast-charging tops out at 250 kW (up from 195 kW), and a 10–80 percent charge takes about 28 minutes. Like other model-year 2027 BMW EVs, the i7 has a NACS charging port.
