    Tesla Roadster充電3.5小時跑390公里~

    【 CARNEWS carnews 】

    這部車的最大馬力、扭力達到248hp/38.7kgm,配上僅1220公斤的車重,0∼96km/h加速僅需時3.9秒,同時在來自MR的車體架構下,操控性也有相當犀利的演出;尤其它充一次電(約3.5小時)可行駛390公里的距離,無怪乎國外名人對它趨之若鶩。

    由英國Lotus車廠組裝生產、年產量約600部的Tesla Roadster,重要革命是動能回生系統並未直接與煞車連結,因此制動反應更為敏銳,當駕駛者放開油門的同時,原本提供動力的電動馬達立即進入能源回生設定,並且可供應後驅動輪6.1kgm的減速扭力。此外,在滑行狀態下駕駛者需依據儀錶板上的能量錶指示,稍微踩下油門才能讓馬達處於不發電又不耗電的順暢滑動模式,而此車的蓄電系統為6800個鋰離子電池構成,加上嚴密的監控電腦、複雜細膩的獨立散熱器與異常自動斷電設計,相對可達到極長的巡航距離。

    最後,Tesla Roadster的車架雖然是來自Elise,但底盤後段原本用來搭載引擎、變速箱與油箱的位置,還針對電池模組與驅動馬達進行修改強化,同時提昇了懸吊部份的強度與支撐力,畢竟電動車還是有重量上的影響
