Source: Jordan Times, AmmanAug.儲存倉 07--Successor to the old Audi 80 and 90 saloons, Inglostadt's compact saloon has gone up in the world in terms of cache, since it adopted the A4 nameplate in the mid-1990s. Now firmly established among the German prestige brand troika, the A4's competitors obviously include the Mercedes C-Class and BMW 3-Series, as well as the Volvo S60 and Infiniti G-Sedan.First launched in 2008, the fourth generation A4 underwent a subtle but effective face-lift in 2012, and with Audi's renowned Quattro four-wheel-<<>>, S-tronic dual clutch gearbox and S-line kit, the A4 has tenacious traction, quick gear changes and a sportier more assertive look.Subtle makeoverBarely different from the pre-facelift model -- or other Audis in general -- at first glance, the 2012 makeover however freshens up the A4's elegant, sleek, assertively business-like and clinically handsome design, even its replacement model creeps nearer. Revised bumpers include honeycomb intakes and added slats. The large looming near-full height grille now looks more muscular and elegant with a small upper tuck, while front lights are straighter on top and sharper and meaner looking, with optional <<>> elements. The sporty S-line package includes subtly muscular bumpers and skirts, and a slightly lower ride height and larger alloy wheels, which well compliment its chiseled and concise lines.Much-praised, the A4's interior busy but elegantly executed, and feels better <<>> this fourth generation, than before. Sporty and elegant, the A4 S-Line's cockpit features large clear dials, instrumentation and infotainment screen, and user-friendly functions. A contoured thick steering wheel is sporty, while leather, metallic and soft texture plastic materials look classy. The large and tall gear <<>> could have been designed more subtly or sportily however. Good equipment levels are matched by decent in-class space, while minimum 480 luggage capacity is good for a compact executive car, and with split folding rear seats, extends to 962-litres. Rear Isofix child seat anchors are standard equipment.Wide range abilityFitted with the second to entry-level petrol engine, the A4 2.0 TFSI's direct injection turbocharged four-cylinder engine however develops 208BHP throughout a wide 4300-6000rpm range and 258lb/ft torque throughout a broad 1500-4200rpm mid-range. For some perspective on how far cars have come and just what is considered powerful, the A4 2.0 -- as one of the least powerful petrol A4 versions -- develops slightly more power and torque than the nearly 400kg lighter and iconic rally-bred 1980 Audi Quattro sports car, which was considered seriously quick back then. The driven A4's 6.5-second 0-100km/h time and 245km/h also beat the performance of early examples of the now classic Quattro.As quick as a compact executive saloon reasonably need be for most buyers, the A4 2.0 TFSI Quattro launches with immediacy off-the-line as all four driven wheels dig into the tarmac, while its' turbo spools up quickly after a brief turbo lag. Once boost builds to its sweet spot the A4 2.0 benefits from a wide maximum torque range, and is responsive, confident, brisk and flexible when overtaking. Maximum power is similarly available over a broad range, while power build-up is underplayed by almost ever-present torque. Combined cycle 7l/100km fuel economy is easy on the pocket, but lighter and rear-<<>> Mercedes C200 does slightly better.Tenacious tractionUsing a modern version of the same innovative and highly effective Quattro four-wheel-<<>> system that debuted on the eponymous 1980 Audi Quattro, the driven A4 Qua迷你倉沙田tro's engine is placed in-line and ahead of the front axle, with power distributed from the gearbox and differential unit to the front and rear wheels. Refined over the years, the system now places the engine as close as possible to the front axle, but as it is longer in-line engine layout in-front rather than on top of the axle, overhang weight is more noticeable than transverse engine and front-to-rear derived four wheel-<<>> systems.Along with Subaru's Symmetrical AWD, the Quattro system is among the most effective four-wheel <<>> systems for road cars, With weight placed on the front wheels and a direct line of power to both front and rear, Quattro offers exceptionally high traction, in slippery, wet and gravelly conditions, and channels high power output very effectively to the road. Delivering both performance and safety advantages, Quattro ensures the A4 is sure-footed and highly effective in putting power down through corners, especially in low traction conditions where it claws back grip and stability by applying power through all wheels. The A4 Quattro also has modern electronic stability and traction controls.Tight dynamicsWith a firm but comfortable, supportive and well-adjustable sports, decent visibility and good noise, vibration and harshness isolation, the Audi A4 2.0 Quattro S-line is a pleasant, refined and reassuring place to be. Smooth and stable on the highway, the A4 drove wonderfully during a short test <<>> on Dubai's smooth roads. Sure-footed through corners, the A4 also has good grip and body control, which are all the better from its S-line spec lower ride height and larger and lower profile 245/40R18 footwear. Tight, planted and confident on smooth highways, the A4 S-line's lower suspension and larger wheels do however make it firm over sharp bumps and cracks.Direct and quick steering adds to the A4's sporty driving experience and is responsive to inputs and clinically accurate, but favours directional stability and refinement over feedback. The A4 Quattro's confident handling is highly competent but also leans to refinement and smoothness over <<>> engagement. Turn-in is crisper and more eager than older Audis. With the engine slung in front, one expects the 2-litre engine's lower weight make this A4 tidier handling and more eager into corners than larger engine versions. But on sudden turn-in or switchbacks, one feels a milder version of the previously more pronounced weight transfer from the nose-heavy engine layout.Technical specificationsEngine: 2-litre, turbocharged in-line 4-<<>>Bore x stroke: 82.5 x 92.8mm<<>> ratio: 9.6:1Valve-train: 16-valve, DOHC, variable timing, direct injectionGearbox: 7-speed dual clutch automated, four-wheel-<<>>0-100km/h: 6.5-secondsMaximum speed: 245km/hPower, BHP (PS) [kW]: 208 (211) [155] @ 4300-6000rpmPower-to-weight: 126.4BHP/tonTorque, lb/ft (Nm): 258 (350) @ 1500-4200rpmFuel consumption, city / highway / combined: 8.8 / 5.8 / 7/100kmFuel capacity: 61-litresLength: 4701mmWidth, with / without mirrors: 1826 / 2040mmHeight: 1427mmWheelbase: 2808mmTrack width, F/R: 1564 / 1551mmOverhang, F/R: 862 / 1031mmAerodynamic drag co-efficient: 0.34Unladen weight: 1645kgHeadroom, F/R: 1015 / 952mmShoulder room, F/R: 1463 / 1442mmHip room, F/R: 1410 / 1380mmLuggage capacity, min / max: 480 / 962-litresSteering: Electric power-assisted rack and pinionBrakes, F/R: Ventilated / discsSuspension, F&R: Multi-link, anti-roll barTires: 245/40R18Copyright: ___ (c)2013 the Jordan Times (Amman, Jordan) Visit the Jordan Times (Amman, Jordan) at .jordantimes.com Distributed by MCT Information Services迷你倉價錢
