BMW has unveiled the all-new i7 xDrive60, the first all-electric 7-Series model.
Unlike Mercedes’ approach, where the EQS sedan and S-Class differ significantly visually, the BMW i7 is integrated into the 7 Series. The i7 and 7-Series are visually similar and share the same body, dimensions and cabin. However, significant differences are below the sheet metal.
The drive itself consists of two electric motors, which means that the i7 xDrive60 has all-wheel drive. The engine that drives the front axle has 259 hp, while the rear has a peak power of 312 hp. The total power of the system is 544 hp and 744 Nm.
The motors themselves do not have permanent magnets and are instead electrically excited synchronous motors. BMW claims that the new engines do not use rare metals.
The BMW i7 xDrive60 can reach 100 km / h from standstill in 4.9 seconds. The i7 boasts a 101.7 kWh battery of useful energy. BMW says the range of the luxury sedan is estimated at 483km which puts it behind rivals such as the Mercedes EQS 580 (547km) and the Tesla Model S Plaid (557km).
The i7 can be quickly charged with power up to 195 kW, and BMW claims it can increase the range by as much as 128 km in just 10 minutes. This is slower than the charging power provided by Porsche Taycan, which can deliver energy at a maximum charging rate of 350 kW. However, BMW strives to attract customers with other technological benefits…
For example, the adaptive recuperation present on BMW iX and i4 is programmed to track traffic lights and detect downhills. Regeneration automatically increases when approaching an intersection, or when moving downhill.
BMW has also optimized the charging software, using lessons learned from the i4 and iX. For starters, fast DC charging temperatures are more precisely controlled, extending overall battery life. While the i7 is charging on a DC charger, the software alters the phases of full and partial cooling in an attempt to reduce battery cell stress and shorten charging time.
Once the battery reaches a higher charge level, the charging speed is gradually reduced, instead of the steep drop that would have been the case earlier. This gives a more rounded charging curve, again shortening the charging time but also the battery life.
Pre-orders for the i7 will open on April 20, and the first deliveries are expected in the fourth quarter of this year.
In addition to the all-electric version of the i7, the new 7 Series will also be available in Europe with traditional SUS engines. It will contribute to ecology through plug-in and light hybrid technology.
For example, the 740d xDrive is a 3.0-liter diesel with light hybrid technology, which means far lower registration costs in our market. As before, the diesel developed 286 hp and 650 Nm, and the starter-generator 18 horsepower and 200 Nm. The total power of the system is 300 hp and 670 Nm. It reaches 100 km / h in 6.3 seconds and the maximum speed is limited to 250 km / h.
The aforementioned diesel will be available from spring 2023, as will the 750e xDrive with 490 hp and the M760e xDrive with 571 hp. For now, the week will be able to run only in the i7 variant, ie with a purely electric drive.
