特斯拉当地时间10月10日发布了Model S P85D,该车性能获得全面提升。该车采用全轮驱动布局，包括一台前置的211马力电机和一台后置470马力电机，综合输出功率达到515千瓦/691马力，扭矩930牛米。由于增加了一台电机，车辆性能也获得提升，0-96公里/小时加速时间3.2秒，比P85快了整整1秒。车辆最初四分之一英里（约合400米）加速时间11.8秒，最高时速250公里，而P85为210公里。除了动力和加速性大幅超越P85外，这辆车的续航里程也增加了16公里，达到443公里。由于增加了前置电机，车重也随之增加132公斤至2239公斤，前后重量分配达到50:50黄金比例。不过，P85D外观并没有显著变化，只是采用了红色刹车卡钳，车尾增加了特斯拉logo。除了P85D，特斯拉还发布了低端的60D和85D,这两款车前后轴都分别搭载了188马力电机。其中60D 0-96公里加速时间5.7秒（后驱版本为5.5秒），85D加速时间5.2秒（后驱版本5秒）。60D最初四分之一英里加速时间14秒（后驱版本13.8秒），85D 13.5秒（后驱版本13.3秒）。60D最高时速201公里（后驱版本209公里），85D最高时速250公里（后驱版本298公里）。60D续航里程362公里（后驱版本378公里），85D 475公里（后驱版本491公里）。这两款车的重量也分别增加了80公斤，60D为2087公斤，85D为2190公斤。除了增加四驱外，三款D版新车型还配备了辅助驾驶技术，比如车道保持、自我调整巡航控制系统。此外，三款新车还支持自动泊车功能，全新的auto pilot技术能使用超声波，探测周围车辆的距离等情况，用以自动控制车距。进入自动巡航阶段之后，该系统可以读取道路限速标识，调整行驶速度、自行变更车道。特斯拉CEO 马斯克表示，将在未来5-6年内推出全自动车型。

 

691 bhp Tesla Model S P85D unveiled with all-wheel drive and 3.2s 0-60 mph sprint

Tesla Motors has taken the wraps off the range-topping Model S P85D which brings a wide array of massive improvements.

 

First and foremost, the vehicle now has an all-wheel drive arrangement thanks to a dual electric motor configuration after installing a 211 bhp front motor which works together with the 470 bhp rear one in order to enable the high-performance Model S pack a combined output of 691 bhp (515 kW) and 687 lb-ft (930 Nm), with 221 bhp & 244 lb-ft at the front and 470 bhp & 443 lb-ft in the back. Thanks to this hardware arrangement, the vehicle needs only 3.2 seconds for the 0-60 mph (0-96 km/h) run which makes it a full second quicker than the previous P85 flagship variant.

 

The quarter mile is achieved in 11.8 seconds while the top speeds stands at an impressive 155 mph (250 km/h) whereas the P85 can't go beyond 130 mph (210 km/h). Aside from being significantly more powerful and quicker than the P85, this all-wheel drive also provides an extra 10 miles (16 km) of range which means it now can do 275 miles (443 km) before running out of juice.

 

Adding the front electric motor has increased the car's weight by 291 lbs (132 kg) to 4,936 lbs (2,239 kg) distributed 50:50. There aren't any significant visual differences as Tesla Motors only added red brake calipers and a badge at the back.

 

Besides the P85D, Tesla Motors has also announced lesser versions in the form of a 60D and 85D which get a 188 bhp electric motor installed on both front and rear axles. The first one runs the sprint in 5.7 seconds (0.2s quicker than the rear-wheel drive version) while the other does it in 5.2 seconds (0.2s faster). The 60D runs the quarter mile in 14 seconds (-0.2s) while the 85D does it in 13.5 seconds (-0.2s). Top speed stands at 125 mph (+5 mph) for the 60D and at 155 mph (+30 mph) for the 85D.

 

As far as range is concerned, the 60D will do 225 miles (+10 miles) while the 85D can travel for up to 295 miles (+10 miles). As expected, weight of both versions has increased by 176 lbs to 4,597 lbs (60D) and 4,824 lbs (85D). Despite being more powerful and heavier, the cars have a higher range which has increased by 10 miles to 225 miles (362 km) in the 60D and to 295 miles (475 km) in the 85D.

 

Aside from introducing these three new all-wheel drive models, Tesla Motors has also announced a semi-autonomous driving system which uses optical cameras to scan the road up ahead. It also has a 360-degree sonar to detect traffic and barricades and will come to a full stop if the traffic in front slows down completely.

 

As a final note, Elon Musk says that we should expect fully autonomous vehicles in the next 5-6 years.
