About Edrive

The EDrive system replaces the existing Prius NiMH battery and Toyota battery control computer with a larger advanced lithium-ion battery and a battery monitoring and control system. The new system aims to allow the Prius to be charged at home using a standard 110/120V home outlet. With the larger battery, the Prius runs in electric only 'EV' mode at lower speeds or when less power is needed. The result is EV driving and electrically boosted gasoline driving for a 40 or so miles with a gasoline efficiency of over 100mpg. After the 40 mile 'boosted' range, the vehicle performs just like a standard Prius until it is plugged in again. The battery system is about 2" higher and 3" longer than the Toyota NiMH battery. It is installed under the rear cargo carpet without limiting access to the spare tire. A small display is mounted on the dashboard.

BMW i7 xDrive60 – the electric dimension of luxury. Test and test drive

Feb 5, 2023

February 5, 2023 The new BMW 7 Series will be available in Poland with three types of drive: with a diesel engine supported by the Mild Hybrid system (740d xDrive), with a Plug-In hybrid system (e.g. 750e xDrive) and fully electric: BMW i7 xDrive60, which is this material. Along with the first test of the internal combustion version – the BMW 740d xDrive – these reports form a whole and I recommend reading the previous article first, especially with regard to the quality and interior equipment. Here I will not discuss all the functions of the passenger compartment of the car, which are identical regardless of the drive version (screenshot from the configurator below), and I will focus on the i7 xDrive60 electric drive itself. More comfort in the electric version The BMW 7 Series is a high-class car that almost touches the luxury (electrically opened/closed doors, interior quality). Especially from the point of view of a VIP sitting in the rear seat (with the possibility of unfolding it), traveling comfort is very important, resulting not only from effective soundproofing, but also from the smooth nature of the drive system. Although in the 740d xDrive version, thanks to the Steptronic gearbox, you really can’t complain about the smoothness with which the gears are changed, the possible start of the engine is basically imperceptible (thanks to the Mild Hybrid), and the soundproofing of the drive unit itself is at a really high level, I can understand that someone who spends almost PLN 1 million on a car can expect even more. This “more” can only be provided by the electric drive, which, due to its characteristics, is characterized by exemplary smoothness: no gearbox, free and immediate access to the power of the system, no “whirr” of the internal combustion engine. This, combined with the other features of the new 7 Series, i.e. the comfortable suspension and excellent soundproofing of the surroundings, makes traveling in the electric BMW i7 xDrive60 an even higher level than traveling in this car in the combustion variant. The distinguishing element of the electric version of “Seven” is the soundtrack composed by Hans Zimmer, a composer who needs no introduction. The VIP can choose the comfort mode he wants to travel in, and this also takes into account the different sound effects when moving (not just accelerating) in the BMW i7 xDrive60. Personally, I think these soundtracks fit the character of the car well, and I’ve driven with them on. Even in sport mode they were not intrusive. The optional Bowers & Wilkins Diamond Surround Sound System with … 36 speakers has an undoubted impact on the reception of these sound effects. The standard is a slightly simpler system, also Bowers & Wilkins with … 18 speakers. Well, even “standard” in the case of the BMW 7 means a very high level. The electric BMW i7 xDrive60 is … heavy, because the weight of the whole car is ~ 2640 kg, which compared to the diesel – 740d xDrive (2180 kg) – is an additional 460 kg of “ballast” that the suspension must bear. Can you feel it while driving? I don’t think so. The car is just as comfortable, comparably compact. In both cases, the air suspension with electrically adjustable anti-roll bars is of great importance. for compensating for roll in turns. As a result, the BMW i7 xDrive60 did not hear the dull “rumble” from the chassis, which is characteristic of electric cars, at least on fairly even roads on which we traveled during the presentation, and even a quick drive over the speed bump was not a major challenge. Sitting in the back seat and working on the laptop, there was absolutely no problem reading the text on the small screen, which is a very good proof of the comfort of the suspension. Of course, as in the case of the combustion variant of the 740d, so in the BMW i7 we still feel that we are driving a BMW that willingly fits into the following corners and which even encourages you to travel faster, which enhances the immediate access to the high power offered by the drive system. BMW i7 xDrive60 during faster, even sporty driving There is no doubt that with such dimensions (almost 5.4 meters long) it is difficult for the BMW i7 xDrive60 to be a thoroughbred athlete, but as I mentioned earlier, this car willingly fits into the next corners and faster driving gives quite a lot of pleasure, at least to the driver: ) This is helped by precise and direct steering, as well as a good sense of what is happening with the wheels. With very tight corners, however, physics is the hardest to bend: the return with a nearly 2.7-ton limousine (with the driver) requires a solid release of the brakes. For sports driving, however, it is better to choose a smaller car, e.g. BMW i4 M50. There is one improvement that the BMW iX and i4 lacked greatly: the “BOOST” paddle on the left side of the steering wheel, which makes the maximum power of the driveline available without changing the driving mode. The point is that as standard (without switching on the sport mode), the BMW i7 xDrive offers 360 kW (490 hp) of power and even the deepest pressure on the accelerator pedal will not get more. Only in sport mode or just after using the “BOOST” paddle, we get access to the full potential: 400 kW (544 hp). Of course, this is not a drastic difference, but when overtaking, sometimes these extra few horsepower can come in handy. The 5th generation of the electric eDrive drivetrain in the BMW i7 xDrive60 The BMW i7 uses the 5th generation of the eDrive drive, which has already appeared in e.g. in the BMW iX3 (range test), and later also in the BMW iX (range test of the xDrive50 variety) and i4 (i4 M50 test). The 5th generation eDrive is distinguished by, among others: in that synchronous electric motors do not use rare earth metals (there are no permanent magnets), and no cobalt from the Democratic Republic of the Congo is used in the production of batteries. On the practical side: in cars such as the BMW iX3, iX xDrive40/50 or also in the BMW i7 xDrive60, the maximum power is available up to the maximum speed of the electric motors, which is not so obvious in the world of electric cars. Typically, there is a drop in power at several thousand revolutions per minute that the rotor of an electric motor reaches. In addition, a significant drop in power resulting from low battery charge occurs with a really small amount of energy stored in them. Here it is worth quoting what it looks like in the case of the BMW iX xDrive50: The batteries are placed in the floor of the BMW i7, the modules themselves are 11 cm high, exactly the same as in the case of the BMW i4 – this made it possible to maintain a low seating position in this car. One of the most important improvements is better battery temperature management. This improves parameters in extremely low and high ambient temperatures. Some updates also apply to the predictive recuperation system. By default – in “D” mode – the electric BMW reacts to other vehicles, speed limits, etc. by adjusting the level of energy recovery or not using it at all (sailing) in a fully automatic way (of course after taking your foot off the “accelerator”). In the BMW i7, this process has been streamlined by taking even better account of intersections, curves and even traffic light data (certain countries). And all this even works without setting a navigation destination or activating semi-autonomous driving. There is also a MANUAL (on request) option to preheat the battery, which is useful in winter conditions when you want to recharge at an ultra-fast charging station. Until now, you had to set a destination in navigation. Of course, the BMW i7 system will heat the battery anyway when we approach a station that we have saved in the system’s memory. Range and energy consumption of the BMW i7 xDrive60 According to WLTP homologation tests, the BMW i7 xDrive60 offers a range of 591 – 625 km. With a battery capacity of 101.7 kWh net (105.7 kWh gross), this means an energy consumption of 17.2 – 16.3 kWh/100 km. This is a low demand for electricity, but still achievable – after all, in the BMW iX xDrive50 I got 15.7 kWh / 100 km over a distance of more than 650 km. And there is no doubt that the i7 will have less aerodynamic drag than the iX. I made a total of three measurements, the longest taking into account over 200 km, mainly on French motorways, and I obtained 20.3 kWh / 100 km, which translates into a range of 500 km “on a single charge”: The BMW i7 can be charged with up to 195 kW of direct current, which means that the energy is topped up from 10 to 80% in approximately 34 minutes. The on-board AC charger has a power of 22 kW, which will allow the battery to be fully charged overnight. It will be possible even if the household connection has a power of 11 kW. BMW i7 M70 A little later, the BMW i7 xDrive60 discussed here will be joined by a more powerful version marked: BMW i7 M70 xDrive, which is to offer 485 kW (660 hp) of power, so even more than the BMW iX M60, whose performance you can see below. At the moment, the acceleration you can count on has not been given, although I would expect a figure lower than 3.5 seconds in the 0-100 km / h sprint. The BMW i7 xDrive60 accelerates to 100 km/h in 4.7 seconds and the top speed is limited to 240 km/h. Cena BMW i7 xDrive60 starts from 650,000. PLN, and the highly equipped version will cost approximately PLN 200,000. more. Of course, the price can be increased even more, e.g. by adding a two-tone body color for … 62,000. PLN, or an entertainment system with an over 31-inch screen inside for PLN 24.5 thousand. zloty. It’s hard to define the ceiling, but you can get close to a million zlotys. The electric version is more expensive than the diesel 740d xDrive by about 120-130 thousand. PLN (assuming the same level of equipment). Opinion The summary should start with the fact that the electric BMW i7 xDrive60 basically has no rivals. The closest positioned car is the Mercedes-Benz EQS, which, however, does not offer such a large interior space or the luxury character of a VIP journey. In other markets, Lucid Air could possibly be considered as a competitor. This puts the BMW i7 in a league of its own. There is no doubt that the BMW i7 is the most comfortable and luxurious variant of the new 7 Series. And this is because of the obvious, which is the smooth and noiseless characteristics of the electric drive. At the same time, the modern and very advanced 5th generation eDrive drivetrain (together with improvements) fits perfectly with the equally technically advanced interior of the vehicle and completes the character of the luxurious and innovative representative limousine – the BMW 7 Series. Most importantly, however, as with most other BMW cars , so a customer interested in the BMW 7 can choose the drive version that interests him: with an internal combustion engine, with a plug-in hybrid drive or in a fully electric version (i7).
