engine (as did the Datsun 710 from 1975), although with only (SAE Net). The federalized 2.0 thus produced less than what was claimed for a Japanese market 1.6. California-spec cars have . The federal/Canadian version took leaded fuel and depended on an EGR system for pollution control, while the California cars have a catalytic converter and require unleaded gasoline. Gross horsepower ratings are 110 and 107 respectively. The 1974s also received larger bumpers mounted on hydraulic cylinders to meet new safety standards, increasing weight by about and making the car longer. The additional weight meant performance still suffered moderately (while fuel consumption dropped by about ten percent) from the higher weight and additional emissions equipment. Until the 1977 introduction of the six-cylinder 810, the 610 was Datsun's largest car sold in North America. New Zealand New Zealand market cars initially were a single 1.8-litre 180B sedan, again with four-speed manual transmission and assembled from CKD kits under contract by Campbell's. A three-speed automatic – using a transmission made by Nissan Japan subsidiary JATCO – was later added as a factory option. Relaxed restrictions on car assembly kit imports and increasing affluence in NZ meant Campbell's, which also assembled Toyota, Renault, Rambler, Hino, Isuzu and Peugeot models over the years, could not meet demand so Nissan-Datsun (NZ) contracted Chrysler/Mitsubishi importer Todd Motors to assemble additional manual 180Bs at its Porirua factory alongside the Chrysler Valiant, Hunter, Avenger and Alpine model ranges and Mitsubishi Lancer sedan and Colt Galant coupe. The Todd-built cars gave Datsun dealers a new range of paint colours all different from those Campbell's offered. Racing history A 610 four-door participated in the 1972 and 1973 East African Safari Rally. Bob Sharp drove his 610 HT race car to second place overall in the American SCCA B Sedan Championship for 1973 and 1974. The same car achieved a first place for the 1976 SCCA B-Sedan Championship but with Elliot Forbes-Robinson driving. 710 series Shortly after the introduction of the 610, Nissan launched a new line of slightly smaller cars January 1973 utilizing parts and styling cues from the 610. This new line of cars was sold in various markets as the Datsun 140J/160J, Datsun Violet, or Datsun 710. In Japan, it was exclusive to Nissan Cherry Store Japanese dealerships as a larger companion to the smaller Nissan Cherry, thereby giving Nissan the opportunity to sell a Bluebird-sized vehicle at
