MEGA; giovanni mereghetti / Universal Images Group/Newscom/The Mega AgencyIf you are buying an older, high-mileage car, a new study suggests EVs may hold up better than their gasoline-powered rivals.The research in the UK looked at 47.4 million MOT tests, inspections that focus on whether a vehicle meets minimum roadworthiness and safety standards.According to Guessing Headlights, the results showed little difference at low mileage, with both types of car passing the tests regularly.However, when it came to cars aged three to eight years with 90,000 to 120,000 miles, 16.5 percent of EVs failed their MOT compared with 22.2 percent of gasoline cars.Looking at even higher mileages, the failure rate was 16 percent of EVs and 23.5 percent for gasoline for vehicles over 120,000 miles.Gareth Lewis/Universal Images Group/Newscom/The Mega AgencyThe study was conducted by New AutoMotive and commissioned by the British Vehicle Rental and Leasing Association (BVRLA).And while it does sound promising for EV owners and potential buyers, there are a number of things the British MOT test does not cover.The MOT doesn't measure an EV battery's state of health, remaining capacity, electrochemical degradation or charging performance.This is a particularly important omission when evaluating or buying an older, high-mileage electric car as it will effect range when traveling and also how long the car could last into the future.Ingram Publishing/Newscom/The Mega AgencySimilarly, the test isn't a comprehensive assessment of engine or transmission health either.The research also showed EVs had fewer suspension issues than gasoline cars, but more tire defects.In the study's conclusions, it states: "The traditional used-car risk model that discounts vehicles past 60,000 miles must be recalibrated."Electric vehicles demonstrate a flat roadworthiness wear curve, making 70,000-to-100,000-mile used electric cars exceptionally reliable propositions."Read More From First for AutosCybertruck Coated in $60,000 Worth of 24-Karat Gold Sold for Shockingly Low Amount at AuctionNew Mazda CX-6e Can Swear at Other Drivers for You With Built-In External SpeakerGeneral Motors Hit With Class-Action Lawsuit Over Transmission Defects in 4 Popular VehiclesThis story Older Electric Vehicles Have Lower Failure Rates Than Gasoline Rivals in New Study first appeared on First for Autos.
