雷克萨斯在东京车展发布了LS+概念车。这款未来主义风格的轿车向人们提前展示了车厂未来几年将推出的旗舰级车型的设计雏形。雷克萨斯解释称，LS+是“一款展示LS未来外观的概念车”。车厂不到一年前刚刚推出了LS全新版本，而该车的产品生命周期又特别长，因此LS+概念车的推出让人感到意外。这是一款硕大，优雅的轿车，展示了LS未来主义设计风格。车头是硕大的标志性纺锤格栅，在激光前大灯下面是散热孔。车身侧面轮廓很顺滑，后面是与行李箱集成在一起的扰流器，车尾同样采用了激光尾灯组。车厢内布满高科技装备，采用了车厂的“高速伙伴”(Highway Teammate)自动驾驶技术，可实现level3自动驾驶，从高速入口至高速出口机动车专用道路中的自动驾驶。可以已经能够实现汇入车道、变换车道、驶离车道、保持车道、维持车距等自动驾驶操作并利用人工智能纪录道路和周边环境数据。雷克萨斯未公布该车细节和规格，不过车身上的蓝色装饰件表明这是一款电动化车型。车厂也未公布内装照片。车厂预计该车的造型元素和技术将在2020年应用于量产车。

Lexus LS+ concept hints at new flagship in Tokyo
Lexus has traveled to the Tokyo Auto Show to introduce a concept named LS+. The futuristic sedan is a preview of what we can expect from the Japanese brand's flagship model in the coming years.

Lexus explains the LS+ is "a concept vehicle that suggests the future look of the LS." The brand launched a brand-new version of its flagship sedan less than a year ago, and the LS' production run has historically been long, so the LS+ Concept comes straight out of left field.

It takes the form of a big, elegant sedan that stands out with a more futuristic interpretation of the LS' design. Bigger than ever, the signature spindle grille fades into air vents positioned right below the laser-lit headlights. Its sleek silhouette flows into a trunk-mounted spoiler, while the rear end gets laser lights.

There's no shortage of high-tech features inside. The LS+ announces Lexus' Highway Teammate technology, which is a fancy term for a level 3 autonomous system. The concept drives itself from on-ramp to off-ramp on the freeway. It merges and changes lanes on its own, and it uses AI to record data about the roads it's on and the surrounding areas.

Mechanical specifications haven't been released yet, though the blue accents on the body hint at something electrified. We haven't seen interior photos, either.

Lexus predicts the LS+'s style and tech will reach showrooms in the early 2020s.
