????梅賽德斯-奔馳智能空氣動(dòng)力汽車（IAA）

????乍一看，你會(huì)感覺(jué)IAA概念車就是一顆華麗的銀色子彈——一款S級(jí)尺寸的四門轎車,。但它并沒(méi)有這么簡(jiǎn)單：這是梅賽德斯在空氣動(dòng)力學(xué)領(lǐng)域的最新嘗試,，其阻力系數(shù)僅有.19，是梅賽德斯車體輪廓最流暢的一款汽車,。

????按下一個(gè)按鈕或?qū)④嚰铀俚匠^(guò)時(shí)速50 英里,，這款智能空氣動(dòng)力汽車的外形會(huì)發(fā)生明顯變化，從車頭和車位伸出的分割部分會(huì)延長(zhǎng)超過(guò)15英寸,。格柵的調(diào)風(fēng)裝置也可以移動(dòng),，側(cè)鰓可以改變空氣流動(dòng)的方向，主動(dòng)式輪轂會(huì)和輪胎外側(cè)形成一個(gè)平面,。這些變化將幫助這款汽車最有效地在空氣中穿行,。

????此外，車內(nèi)也有多款未來(lái)的系統(tǒng),，如所謂的“Car-to-X”技術(shù),。該公司表示，這項(xiàng)技術(shù)使IAA可以“偵測(cè)到街角的車輛”,，并通過(guò)與其他車輛和數(shù)據(jù)源分享信息,，避免交通事故?；诜较虮P的觸摸控制,，允許駕駛員將手懸停在一個(gè)緊湊安全的空間內(nèi)，操作多種功能,，就像手扶在方向盤上一樣,。

????Mercedes-Benz Intelligent Aerodynamic Automobile (IAA)

????At first glance, the Concept IAA is simply a stunning silver bullet—an S-Class-sized four-door coupe. But there’s more to it: It’s Mercedes’ latest exercise in aerodynamics, and with a coefficient of drag of just .19, it’s the German automaker’s slipperiest silhouette yet.

????Push a button or accelerate past 50 mph, and the IAA literally shape shifts, with segmented sections that extend from the front and the tail of the car, lengthening it by more than 15 inches. Louvers in the grille can move, side gills redirect air flow and active wheel rims become flush—all to help the IAA most effectively cut through the air.

????There are plenty of future systems on board, too, such as so-called “Car-to-X technology,” which the company says allows the IAA to “l(fā)ook around the corner” and avoid accidents by sharing information with other cars and data sources. And steering-wheel-based touch controls allow the driver to hover over and operate multiple functions in a compact and safe—as in hands on the wheel—space.
