AUDI A3 2.0T

Before our review of this brand new model from Audi, we have to mention 2 technical innovations involved with this model: DSG (direct shift gearbox), and the 2.0L FSI (Fuel Stratified Injection) engine, which just garnered the honor of International Engine of the Year.

First of all, the new A3 resides at the bottom of the Audi family, but it contains the most advanced technology that is shared through out Audi’s product range. The DSG is a good example. This is an automatically shifting manual gear box. It can be operated as a normal automatic transmission, but it is actually an electronically controlled double clutch plate manual transmission. In manual mode, it shifts much faster than normal human can, and more efficient than a normal manual transmission.

The turbo charged 2.0L FSI engine is another innovation. Maximum output is at 200 hp @ 5100 – 6000 rpm, and 207 lb-ft @ 1800 - 5000 rpm. We were really addicted to the flat power band of this engine. Instant power on demand, whether it’s in the city or on the highway, this power plant can handle with ease.

A3 has a smartly designed exterior. It is a 5 door hatchback/wagon. The look is solid yet sporty. A large air dam underneath the Audi family trapezoid grill gives out an aggressive stance. The wheel wells are filled with 17” alloy wheels with meaty rubber. The look is purely German.

The interior’s design is purely Audi. The excellent fit and finish is standard. The touch and feel is above average. Back seat passengers have ample room to move around. Split folding back seats can increase the already excellent 19.52-cu.ft. of cargo space. The ride is firm and quiet.

Starts at $25460, we think this A3 is an excellent value. It offers enough performance to qualify as a sports sedan, also enough utility to qualify as a family vehicle. The combination of luxury, comfort, and performance makes it one of a few vehicles that stand above the crowd.

在提到AUDI這款Sportback前,兩項技術您不能忽略!首先是被VAG集團廣為運用的DSG(Direct Shift Gearbox)變速箱,另一個便是甫贏得International Engine of the Year殊榮的FSI動力系統。

開宗明義先討論技術部分,是因為A3除扮演四環小兄弟角色外,新車款裡面運用的科技成分濃厚。筆者首度嘗試DSG系統是試駕TT,基本上這是手排變速箱,但操作與自排所差無幾,其特點是透過兩組電子離合器減少換檔震動,晃眼般的切換速度絕非人類可及,燃油效率是另一重點,甚至比手排車更省油。

接著,是讓筆者印象頗為深刻的FSI(Fuel Stratified Injection)渦輪引擎,這項技術如今成為業界話題,起源於參戰法國LeMans耐力賽經驗,汽缸內直噴技術雖不稀奇,但高壓縮比設計還搭配渦輪增壓頗為罕見。

FSI是採稀薄燃燒(Lean Burn),也就是汽缸內油氣混合比約60:1,比目前點式噴射供油引擎相較更省油。低轉速下FSI吸入大量空氣,讓引擎中低轉速時,保持油氣混合集中在燃燒室火星塞周邊,燃燒室外則被新鮮空氣包圍。其優勢是觸媒減少氮氧化物。引擎監測器持續偵測觸媒內含量,每60秒清除一次內部氮氧化物,達到高效率、環保的均衡輸出。這些是邂逅A3華服下的內涵,也是AUDI架構性能優勢的技術核心。

聽到這些專業術語讓您頭昏眼花?那就觀察一下AUDI如何讓小車也有高級感。A3車頭搭配依循家族傳統,梯形水箱護罩及下氣壩成就的氣勢,讓人無法與廉價字眼相提並論。側面、後方來看,以鍍鉻材料點綴和紮實鈑件交錯,加上碩大的17吋輻射狀鋁圈和225/45R17跑胎,整輛車賦予一股沈穩、內斂,單憑外觀可接受這是輛高級車,各部細節也完整陳述德國硬派觀點。

進入座艙筆者感受到務實取向,但選用材料和配置不寒酸!質感在水準之上,怠速、行駛的隔音品質令人滿意,後座空間充裕,行李廂空間容量19.52cu.ft.,仰賴可分離折疊後座造就的彈性空間讓人無法挑剔,可以察覺設計師的匠心巧思,在典型五門掀背乘坐環境裡塑造質感,實用、高級感兼具,讓筆者心跳不已。

筆者個人很喜歡AUDI設計的方向盤,造型和中間醒目的四環標識搭襯協調,握感、大小適中,隱藏於後的DSG壓板位置選定恰到好處,將身軀靠在密實的跑車座椅上,運動氣息難掩。配備部分,試駕的Sports Package雖沒拉風的Open Sky System,但分區恆溫空調、HID、感應雨刷和電子動態穩定裝置等,便非一般入門掀背車能提供。


A3隔音蠻聰明的,阻絕底盤噪音、風切聲但保留駕駛者聆聽引擎、排氣聲浪的權利,重踩油門時除隱約傳遞的貼背感,音頻傳遞下也多了幾分快感。這具由VAG集團主導的四缸FSI渦輪引擎,增壓比高達10.3:1,最大輸出200hp/5,100-6,000rpm,最大扭力為207lb-ft/1,800-5,000 rpm。這種平頂式輸出曲線讓人上癮,油門輕送力道便源源不絕,是少數市區、公路都可應付自如的車種,充裕推力讓出入彎道多了點灑脫,出彎時需退檔只消彈指,另一股渾厚扭力又將車子往前送,零到60mph加速僅6.7秒;極速突破130mph以上實力A3非浪得虛名。

難道A3這麼完美?實則不然!罩門還是在重量配置,3329
磅的體態加上FF配置,在山路操控還是小有難度。FSI引擎在2,000rpm後渦輪驅策,面對坡度較陡或連續彎時疲態叢生,令人欣慰的A3後懸採多連桿獨立結構,取代以往VAG車系扭力樑非獨立設計,兼顧運動性與舒適性,這是最值得稱許的部分,至於彎道反應暢快有餘、犀利不足,可能是筆者期待太高所致。

其實A3這輛車個人覺得物有所值,思索2.0T的25,460美元起價,同級裡兼具舒適、豪華、性能,附加品味不流於俗的雅痞氣質,A3魅力無法抗拒,FSI引擎表現令人滿意但DSG...筆者個人不太鐘意,順暢、快捷的反應造就便利,卻難以說服自己這是輛手排車,踩離合器用力換檔、轉動方向盤的快樂,是讓人迷戀駕馭手排車的誘因,少了這種樂趣會讓筆者血液辛烷值降低,幸而六速手排仍在選擇清單內,讓A3個性及感性相互輝映,成為北美AUDI最閃亮的新星。
