What Is 1985 New Zealand Grand Prix

Overview

The 1985 New Zealand Grand Prix was a significant event in the country's motorsport calendar, marking the 30th running of the race under that name. Held on January 13, 1985, it formed part of the 1984–85 New Zealand Formula Pacific Championship, attracting top regional drivers and international competitors.

This race was notable for its competitive field and the return of the Grand Prix to Manfeild Autocourse, a circuit known for its technical layout and challenging corners. The event drew a strong local crowd and served as a key early-season race for drivers preparing for the broader Formula Pacific series.

• David Oxton claimed victory, becoming the first New Zealander to win the event since 1980, driving a Ralt RT4/85-Ford.
• The race was contested over 50 laps, covering approximately 125 kilometers, with an average lap time of 1 minute 18 seconds.
• Manfeild Autocourse, located near Feilding, featured a 3.2-kilometer circuit with 12 turns, combining high-speed straights and tight corners.
• The 1985 edition was the third round of the 1984–85 Formula Pacific Championship, which spanned five events across New Zealand.
• Second place went to Mike Thackwell, a former Formula 1 test driver, highlighting the high caliber of competition despite the regional focus.

How It Works

The New Zealand Grand Prix in 1985 followed the Formula Pacific regulations, a single-seater racing formula developed in the late 1970s to promote open-wheel racing in the Asia-Pacific region.

• Formula Pacific: A specification-based open-wheel formula using 1.6L production-based engines, designed to control costs while maintaining performance.
• Ralt RT4: The dominant chassis in 1985, built by British manufacturer Ralt, used by top drivers including race winner David Oxton.
• Ford BDA Engine: A 1.6L DOHC four-cylinder engine producing around 180 horsepower, standard across Formula Pacific entries.
• Championship Points: Drivers earned points based on finishing position, with 9 for first, 6 for second, and so on down to 1 for sixth.
• Qualifying Format: A single timed session determined grid placement, with the fastest lap securing pole position.
• Race Strategy: With no pit stops required, the focus was on mechanical reliability and driver consistency over 50 laps.

Comparison at a Glance

The 1985 New Zealand Grand Prix can be better understood by comparing it to other Grand Prix events of the era, both regionally and internationally.

This comparison highlights the regional nature of the New Zealand Grand Prix, which, while not part of the Formula 1 World Championship, played a vital role in developing local talent. Unlike the F1-level Australian Grand Prix held the same year, the New Zealand event focused on cost-effective single-seaters, offering a platform for emerging drivers. The use of Ralt chassis was common across Pacific Formula events, linking New Zealand’s race to a broader regional series. While international stars like Senna competed in similar machinery elsewhere, the 1985 NZ GP emphasized national pride and domestic competition. The event’s format and technical regulations ensured close racing and parity among entries.
