The Mantelson KM 334, unveiled under the project name Mantelson A3447, is a sports coupe introduced in 1958 by Mantelson Motors, and originally designed by founder Dr. James Mantelson 4 years before. When Mantelson died in 1964, The car had already been in production for six years. It was unveiled at a motor show in 1956, and it went into production two years later.

The engine in the current KM334, the KM334 V12 RLS, is a 672 BHP 6.72 liter twin-turbocharged V12 engine, capable of accelerating from a standstill to 60 miles per hour in just under three seconds (2.835 seconds was the official figure), and the car's top speed was a widely disputed 213.346 miles per hour (343.48706 kph). The original car, the KM334 Mk.I, was a sedan that was produced from 1958 until 1962. Its engine was a 2.7 liter I4, which only produced 216 BHP. The car's top speed was 127 MPH, but it got to 60 in 7.8 seconds.

The next version, the KM334 I6, had a 352 BHP 3.5L I6 engine. Its 0-60 time was 6.3 seconds, and its top speed was 152 MPH. It was sold from 1963 until 1974, when it was replaced by the V6 M. The V6 M was powered by a twin-turbo V6, producing 394 BHP, and had a top speed of 163 MPH. Its production ceased in 1989. It got to 60 in 4.7 seconds.

The next variant (KM334 V8) was produced until 2003. It had a 4.8 L V8 with 463 BHP, capable of sending the car to 60 in just under 4 seconds, and its top speed was 193 miles per hour. Its successor, the KM 334 V12, had, as its name suggests, a 5.6 L 593 BHP V12 engine. It could get to 60 in 3.6 seconds, and the top speed was 207 MPH. At the time, it was the fastest car Mantelson had produced. In 2008, it was replaced by the V12 RLS, which, as expected, broke the V12's record.
