The McLaren MP4/3 is a Formula One racing car built and run by McLaren International during the 1987 Formula One World Championship. It was designed under the leadership of American engineer Steve Nichols, after John Barnard quit the team in August 1986. It was the first all-new chassis design for McLaren International since the successful MP4/2 series of cars debuted at the start of the 1984 season.

The MP4/3’s aerodynamics were completely different from the MP4/2, and the car appeared much more low-slung, to take advantage of the maximum fuel capacity limit of 195 litres, rather than the 220 litre limit in effect from 1984 to 1985. With addition of side-ducted radiators, the car’s basic exterior shape was all-new and sleeker than its predecessor. However, it carried over the suspension geometry and gearbox design from the MP4/2. The engine was the 1.5 litre TAG-Porsche twin-turbo motor, but with slight changes in compression and engine balancing.

MPEG-4 Part 14 or MP4 (formally ISO/IEC 14496-14:2003) is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The only official filename extension for MPEG-4 Part 14 files is .mp4.

Some devices advertised as "MP4 Players" are simply MP3 Players that also play AMV video or some other video format, and do not necessarily play the MPEG-4 part 14 format.

MPEG-4 Part 14 is an instance of more general ISO/IEC 14496-12:2004 (MPEG-4 Part 12: ISO base media file format) which is directly based upon QuickTime File Format. MPEG-4 Part 14 is essentially identical to the QuickTime file format, but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features. MPEG-4 Part 14 revises and completely replaces Clause 13 of ISO/IEC 14496-1 (MPEG-4 Part 1: Systems), in which the file format for MPEG-4 content was previously specified.

Neil Oatley (born June 12, 1954) is currently Design and Development Director for the McLaren Formula One team.

Graduating from Loughborough University in 1976 with an Automotive Engineering degree, Oatley worked briefly outside motor racing before joining the Williams team in 1977. There he became one of many young engineers to have worked alongside Patrick Head early in their careers before moving on to other organisations. Oatley worked as a draughtsman before becoming a race engineer for both Clay Regazzoni and Carlos Reutemann.

In 1984 Oatley was recruited by Carl Haas to work on the FORCE F1 project but the results were poor and the team withdrew from Formula One in 1986.

Oatley joined the McLaren team shortly after leaving FORCE and worked alongside John Barnard in the design office. Barnard was soon replaced by Gordon Murray whose MP4/4 chassis almost completed a clean sweep of victories in 1988, and when Murray moved to the new McLaren road car project Neil Oatley was made Chief Designer, his cars securing titles in 1989, 1990, 1991, 1998 and 1999.
