Well, the record is all-metric, because that is all Guinness recognizes (per the article). But the article is an odd mix of metric and traditional units: http://www.studentnewsie.com/hennessey-venom-gt-sets-the-fastest-0-300kmh-production-car-record-15911/
I particularly enjoy the mixed mode paragraphs where the two runs, 0-300 km/h with done with 4 mph tailwind and 6 mph headwind, or the power mass ratio of 1 HP/kg. These students are READY for a job at the BBC, confusing millions.
