特斯拉（Tesla）Model 3最誘人的功能之一添加了新細節(jié)——在“賽道模式”下，這款車不再只是速度快，而更像《速度與激情8》里的定制賽車。賽道模式是高性能版Model 3的特色之一，還配備了雙電機和四驅(qū)功能，售價為6.4萬美元至7.8萬美元。上個月開始，該款已開始向商家和用戶供貨。

今年5月，特斯拉的首席執(zhí)行官埃隆·馬斯克曾表示，高性能版Model 3“將秒殺任何同類車型”，也就是奧迪A5和寶馬3系等入門級跑車。馬斯克之所以信心十足，該車型強勁的動力也是原因之一——獨立測試表明，高性能版Model 3的0-100公里加速時間居然僅需3.3秒。

所有可選配件、輪胎和噴漆等包括在內(nèi)（不含自動駕駛功能），全車價格7.8萬美元，跟寶馬M3差不多，但速度要快15%，操控性也更好。秒殺所有同類車型。——埃隆·馬斯克

但光憑加速度強勁征戰(zhàn)賽道還不夠，而且實際上賽道模式并未真正提升Model 3的性能。正如汽車雜志《Road and Track》詳細披露的最新道路測試結(jié)果，該模式改變的是車輛的剎車和操控方式，從而讓技藝高超的駕駛者獲得更多的靈活性。這其中就包括降低制動防抱死系統(tǒng)（ABS）等安全系統(tǒng)的反應(yīng)速度，也就是高速行駛時干預(yù)操控的功能。

該模式調(diào)整了Model 3的再生制動系統(tǒng)，車輛在轉(zhuǎn)彎時重心前移，從而實現(xiàn)過度轉(zhuǎn)向，也就是通常說的“漂移”。類似操控機制和速度關(guān)系不大，更多是提升駕駛的樂趣。據(jù)《Road and Track》介紹，高性能版Model 3進一步強化了類似無聊好玩的功能。測試員鮑勃·索羅卡尼奇寫道：“沒有掩蓋一切聲響的引擎轟鳴。”駕駛者在感知汽車牽引力并做出反應(yīng)時“將有全新體驗，在轟然作響的燃油車里絕無可能?！?

當然，在賽道上釋放激情需要能量。賽道模式也會限制輸出功率，確保Model 3的部件溫度維持較低水平，從而穩(wěn)定運行。這也意味著在連續(xù)跑3-4圈后，Model 3的動力會稍微減弱，但不至于令人掃興。

電池續(xù)航能力方面，索羅卡尼奇的報告說，在賽道上疾馳了“整整一上午”后（測試者用了兩輛車，只在換車時稍事休息過幾次），測試使用的Model 3還能行駛40英里左右。

特斯拉明確表示，該功能不適合通勤途中使用。選擇賽道模式后，中控屏上會出現(xiàn)警告，提醒駕駛者該功能“僅限封閉賽道”。由于特斯拉有無線升級（over-the-air）系統(tǒng)，該功能仍在微調(diào)。但索羅卡尼奇表示，就算不升級，高性能版Model 3也已成為“世界上首款真正具有賽車性能的電動跑車。”（財富中文網(wǎng)）

New details have emerged about one of the most lusted-after features of the Tesla Model 3: a “Track Mode” that makes the car handle less like a very fast sedan, and more like a custom racer from The Fast and the Furious. Track Mode is included in the Performance version of the Model 3, the $64,000-$78,000 top-of-the-line model which also includes dual-motor All Wheel Drive. It started reaching showrooms and buyers last month.

Tesla CEO Elon Musk claimed back in May that the Performance Model 3 would “beat anything in its class on the track”—that is, other entry-level luxury sports sedans like the Audi A5 and BMW 3-Series. Fulfilling that promise is partly down to raw power, and independent tests have tracked the Model 3 Performance going from 0-60 in a fantastic 3.3 seconds.

Cost of all options, wheels, paint, etc is included (apart from Autopilot). Cost is $78k. About same as BMW M3, but 15% quicker & with better handling. Will beat anything in its class on the track.

— Elon Musk

But mere acceleration doesn’t make a car ready for the racetrack—and in fact, Track Mode doesn’t enable any performance enhancements per se. Instead, as described in a detailed new Road and Track road test, it changes how the car brakes and handles, allowing skilled drivers more flexibility. That includes toning down the reactions of safety systems including anti-lock brakes, which can interfere with high-speed maneuvering.

It also includes rebalancing the car’s regenerative braking systems to shift weight forward on turns and allow oversteering—sometimes known as “drifting.” It’s a maneuver less about speed than just having fun, and according to Road and Track the Performance Model 3 takes such automotive tomfoolery to new levels: “With no engine noise to out-shout everything,” writes tester Bob Sorokanich, drivers can sense and respond to the car’s traction “at a level you’ve never experience in a bellowing internal-combustion car.”

Of course, burning up a track also burns energy, but Track Mode adds a power-throttling feature that keeps the car’s components cool enough to operate reliably. That also means it gets less punchy after three or four back-to-back laps, but not enough to ruin the fun.

As for battery life, Sorokanich reports that “an entire morning” of high-speed track stunts, with cool-downs as the testers swapped between two cars, left about 40 miles of range on the Model 3 batteries.

Tesla is making it clear these features aren’t for your daily commute—when a driver selects Track Mode, a warning screen reminds them it’s “designed to be used exclusively on closed courses.” Track Mode is also still being fine-tuned, possible thanks to Tesla’s over-the-air update systems. But even in its current form, Sorokanich declares it makes the Model 3 Performance “the world’s first electric sport sedan with bona fide race track chops.”
