From a mechanical standpoint it was essentially an evolution of its predecessor, the Alfasud, whose floorpan, chassis and drivetrain were carried over—albeit with modifications to the suspension and braking system. The Nissan-based Alfa Romeo Arna was launched shortly after, offering a similarly sized but lower priced car. The 33 has a unique place in the Alfa Romeo history, as nearly 1 million of these cars were produced. During its 11-year lifespan the 33 saw a light facelift in 1986 and a significant restyle in 1989. The 33 was discontinued in 1994 and replaced by the Alfa Romeo 145 and 146, which used the same boxer engines but built around an entirely new platform based on the Fiat Tipo. ==First series (1983–1986)== Initially known as the Alfa 33 (Type 905), the 5-door hatchback was launched in 1983 and a station wagon version (initially badged Giardinetta, later badged Sportwagon) was introduced the following year at the same time as a four-wheel drive version of the hatchback. The hatchback was styled by Ermanno Cressoni at the Centro Stile Alfa Romeo, while the station wagon was designed by Pininfarina. The 33 became renowned for its nimble handling and powerful boxer engines, but also became equally well known for its unreliable electronics and tendencies to rust (a frequent complaint on Italian cars in general at the time). Another issue was its braking and increased unsprung weight—the Alfasud's inboard front disc brakes (mounted on the gearbox) had been moved to the more common outboard discs (mounted on the wheel hubs). The rear discs of the Sud's four-wheel disc arrangement had also been replaced with drums. The car featured numerous innovations for the company, including an instrument binnacle that moved up and down with the adjustable steering wheel, and a plastic bonnet. The UK launch promoted the sleek design,〔''The Glasgow Herald'' - June 16, 1983〕 and the Daily Mail noted its low drag coefficient of 0.36,〔''Daily Mail Motor Review 1984''〕 and very impressive in 1983 with only bigger cars such as the Ford Sierra and Audi 100 able to better it. At launch two models were available, 33 1.3 and 33 1.5 Quadrifoglio Oro. Both engines were SOHC boxers fed by a twin-choke carburettor, carried over from the Alfasud along with its 5-speed gearbox: a 1350 cc developing at 6,000 rpm, and a 1,490 cc developing at 5,800 rpm. Unlike on the Alfasud, fifth gear acted like an overdrive gear and top speed was reached in fourth.〔 The luxurious 1.5 Quadrifoglio Oro (Gold Cloverleaf in the UK) was distinguished by a silver grille, two-tone paintwork (metallic paint upper body separated by a brown tape from the dark brown lower body and bumpers) and clear front turn indicator lenses outside; by beige Texalfa leatherette/cloth interior, a woodtone steering wheel and shifter knob inside. Standard equipment included bronze tinted glass, headlight wipers, twin wing mirrors and trip computer. A four-wheel-drive variant, the 33 1.5 4x4, was introduced in at the 1983 Frankfurt Motor Show and commercialised in December. It was assembled by Pininfarina in Grugliasco, Turin.〔 Normally front-wheel drive, the four-wheel drive system could be engaged manually by the driver at any speed, via a handle in front of the gear lever. Like the Quadrifoglio Oro the 4x4 was characterised by two-tone paint, either metallic red or silver separated from a black lower body by a double white pinstripe; the grille matched the body colour. Equipment level was also the same as on the richer Quadrifoglio Oro; ride height was raised in comparison to standard 33s. The 33 1.5 Giardinetta (Estate in the UK), a 5-door estate designed and—like the 4x4 hatchback—assembled by Pininfarina, made its début at the March 1984 Geneva Motor Show. The Giardinetta went on sale in 4x4 guise in June and was joined later in the year by a front-wheel drive model, shown at the Turin Motor Show in November. Another Quadrifoglio top of the range model, this time the sporting 1.5 Quadrifoglio Verde (Green Cloverleaf in the UK), was put on sale in June 1984. It was powered by a version of the 1,490 cc boxer, equipped with double twin-choke carburettors like on the Sprint 1.5 QV coupé; Alfa Romeo claimed a top speed of over .〔 The Quadrifoglio Verde could be recognized from its specific grille, additional plastic spoilers under both body-colour bumpers, side skirts, and grey 8-hole alloy wheels with low profile 185/60 HR14 tyres; it was only available in two paint colours—Alfa red or optional metallic silver—highlighted by a light grey stripe in the body side indent. In the cabin there were sport seats in black and grey cloth, a leather covered steering wheel and additional gauges for voltmeter and oil pressure. October 1984 saw the introduction of the updated model year 1985 range, later displayed at the 60th Turin Motor Show. The main change was the introduction of one-choke-per-cylinder carburettor setups—like on the Quadrifoglio Verde—on all models but on the base 1.3. This gave birth to the 33 1.3 S, a sportier 1.3 which put out at 5,500 rpm, or 10 PS more than the standard; the 1.5 on the estates and Quadrifoglio Oro now had . Minor changes were made to the equipment of most models but the recently introduced 1.5 QV, such as the adoption of side skirts and a black grille on the Quadrifoglio Oro. With the arrival of the 1.3 S and front-wheel-drive Giardinetta, for 1985 the lineup included seven models: 1.3, 1.3 S, 1.5 Quadrifoglio Oro, 1.5 Quadrifoglio Verde, 1.5 4x4, 1.5 Giardinetta and 1.5 Giardinetta 4x4. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alfa Romeo 33」の詳細全文を読む スポンサード リンク
