宝马在去年2月发布的740e混动车似乎生命周期很短。在最近举行的SEMA改装车展上，宝马发布了配备MPerformance组件的插电混动车型，而740e将于明年将退役以便为新款745e腾出空间。虽然目前不清楚745e的规格，但据宝马博客报道，升级版车型不仅动力更强，而且在纯电动模式下的续航里程也进一步增加。目前的740e搭载一台2.0升四缸涡轮引擎，功率255马力，另有一台111马力电机，综合功率322马力，扭矩500牛米。车辆0-96公里/小时加速时间5.1秒，最高时速209公里。目前还无法预计745e的性能指标，当然性能提升总是好事，尤其是现行版740e搭载的9.2千瓦时锂电池组在纯电动模式下的续航里程为14英里（约合22.5公里），如果745e能进一步延长续航里程就更好了。另外，宝马2015年3月发布的X5xDrive40e，同样的动力组合，功率308马力，扭矩450牛米，同样搭载9.2千瓦时锂电池，纯电动续航里程22.5公里。不过，不要指望xDrive45e的性能会有很大提升。宝马博客没有提及新车价格的变化，现行的740e在美国零售价为90700美元（约合人民币59.86万元），而X5xDrive40e为63500美元（约合人民币41.9万元）。这两款车将于明年下半年上市。
More Potent BMW 7 Series And X5 Hybrids In The Works
The BMW 740e was originally unveiled in February 2016 and it seems it’s going to have a very short life cycle if we were to rely on a new report. The plug-in hybrid fullsize sedan currently being displayed by BMW at SEMA with an array of M Performance parts will allegedly be retired as early as next year to make room in the lineup for a new 745e. Technical specifications are not available at the moment of writing, but BMWBlog reports the improved version will not only have more power, but also an extended range in electric mode.
As a refresher, the current 740e combines a turbocharged 2.0-liter four-cylinder engine rated at 255 horsepower with an electric motor good for 111 hp. With the power of the two combined, the electrified 7 Series provides a total of 322 hp and 369 pound-feet (500 Newton-meters) of torque. That’s enough for a swift acceleration to 60 mph (96 kph) in 5.1 seconds before topping out at 130 mph (209 kph).
We are not expecting these numbers to go through any drastic changes for the 745e, but any improvement is more than welcome, especially when it comes down to the current electric range of just 14 miles provided by the 9.2-kilowatt-hour lithium-ion battery pack. As far as the other plug-in hybrid, the X5 xDrive40e was introduced in March 2015 with 308 hp and 332 lb-ft generated by the same combo: 2.0-liter gasoline engine with electric motor. It takes 6.5 seconds to do the sprint and will max out at the same 130 mph. The plug-in hybrid SUV also utilizes a 9.2-kWh battery with enough juice for 14 miles.
Again, don’t expect the xDrive45e to be a vast improvement over the existing version.
The report doesn’t mention whether the upgrades will be reflected in the starting price of the two plug-in hybrids. The existing 740e can be had in the United States from $90,700 MSRP while the X5 xDrive40e retails for $63,500. Their replacements are slated to arrive in the second half of 2018.
