 cars two weeks before. Falling sales of the traditional MG models caused a change of heart, and the car, initially to be called the UA-series, was brought back. As it was so different from the older MG models it was called the MGA, the "first of a new line" to quote the contemporary advertising. There was also a new engine available, therefore the car did not have the originally intended XPAG unit but was fitted with the BMC corporate B-Series type allowing a lower bonnet line. The MGA had no exterior door handles.

Twin-Cam

A high-performance Twin-Cam model was added for 1958. It used a high compression (9.9:1 later 8.3:1) DOHC aluminium cylinder head version of the B-Series engine producing 108 hp. Due to detonation problems, a 100 bhp low-compression version was introduced later. Four-wheel disc brake

s by Dunlop were fitted, along with Dunlop peg drive knock-off steel wheels similar to wheels used on racing Jaguars, unique to the Twin-Cam. These wheels and chassis upgrades were used on a small number of "DeLuxe MGA 1600 Roadsters" built after Twin-Cam production came to a halt. Aside from the wheels, the only outside identifier was a "Twin-Cam" logo near the vent aside the bonnet.
The temperamental engine was notorious for warranty problems during the course of production, and sales dropped quickly. The engine suffered from detonation and burnt oil. Most of the problems with the Twin-Cam engine were rectified with the low compression version, but by then the damage had already been done. Many restored Twin-Cams are running more reliably today than they ever did during production. The Twin-Cam was dropped in 1960 after 2,111 (2,210 according to some) had been produced. Production ended in April 1960, but had slowed to a trickle long before.

An open car was tested by the British The Motor magazine in 1958 and was found to have a top speed of 113 mph (181.9 km/h), acceleration from 0–60 mph (96.6 km/h) in 9.1 seconds and a fuel consumption of 27.6 mpgimp was recorded. The test car cost £1,283 including taxes of £428.

1600 and 1600 De-Luxe

In May 1959 the standard cars also received an updated engine, now at 1588 cc producing 78 bhp . At the front disc brakes were fitted, but drums remained in the rear.

31,501 were produced in less than three years.

Externally the car is very similar to the 1500 with differences including: Amber or white (depending on market) front turn indicators shared with white parking lamps, separate stop/tail and turn lamps in the rear, and 1600 badging on the boot and the cowl.

A number of 1600 De Luxe versions were produced with leftover special wheels and four wheel disc brakes of the departed Twin-Cam, or using complete modified Twincam chassis left redundant by the discontinuance of that model. Seventy roadsters and 12 coupés were built.

A 1600 open car was tested by the British magazine The Motor in 1959. It had a top speed of 96.1 mph (154.7 km/h) and could accelerate from 0–60 mph (96.6 km/h) in 13.3 seconds. A fuel consumption of 29.7 mpgimp was recorded. The test car cost £940 including taxes of £277.

 size was increased again to 1622 cc by increasing the bore from 75.4 mm (3 in) to 76.2 mm (3 in) for the 1961 Mark II MGA. It also had a higher ratio 4:1 rear axle, which made for more relaxed high-speed driving. An inset grille and Morris Mini tail lamps appearing horizontally below the deck lid were the most obvious visual changes. 8,198 Mark II roadsters and 521 coupés were built.
As with the 1600 De Luxe, there were also some Mark II De Luxe versions; 290 roadsters and 23 coupés were produced.

Competition history

The MGA's bodywork was based largely on that of a one-off MG TD specially built by the MG factory at the request of racing privateer George Phillips for the 1951 24 Hours of Le Mans. Later, a new chassis was designed so as to seat the driver lower in the car with even cleaner bodywork resulting in the EX 175 prototype.

The later MG prototype EX 182 was very close to the final production MGA and was the car actually raced at Le Mans in 1955. Three MGA prototypes were entered at Le Mans

 competition the MGA has won numerous regional and national championships. It has also been a favorite choice of those competing in vintage racing. The MGA continues to win races even at the highest levels. Kent Prather has been the most successful American MGA driver to date with G Production wins at the SCCA national championships in 1986, 1990, 1995, 2002, 2003, and 2005. Prather and his MGA accomplished this despite the fact that his MGA was often the oldest vehicle competing among several hundred race cars at the SCCA Runoffs.

The car made numerous appearances in the first half of the picture, often with camera work that seemed suspiciously marketing-like, panning back to the car or putting the car under complimentary soundstage lighting. Elvis so liked the car he bought it for himself, and after changing hands once or twice, he re-acquired the vehicle, which is now at Graceland with his Lincolns
