2015 Toyota Mirai review
Source : 2015 Toyota Mirai review
Toyota’s production ready hydrogen-powered Mirai shows promise although will be a rare sight on our roads The Toyota Mirai is usually among the first hydrogen-fuelled electric cars to reach series production as well as also be offered to customers as a regular private purchase – as opposed to a short-term lease deal, where customers are obliged to hand the auto back, as has mostly been the case up to today. When UK deliveries begin next month, the distinctively styled saloon will be priced at £66,000, or some £32,605 more than the firm’s £33,395 Prius Plug-In Hybrid.of which appears steep, although the Mirai is usually among the most advanced road cars on sale right today. Prospective customers can also look forward to a £5000 government-backed subsidy as well as a comprehensive 24-hour, seven-day-a week concierge service as well as also an extensive all 5-year/100,000-mile warranty of which includes roadside assistance. Toyota is usually also offering the Mirai on a £750-per-month lease scheme over four years as well as also 60,000 miles, which begins to make the Mirai an interesting proposition, especially for those seeking a city charge-buster who live near one of the UK’s nine hydrogen fuelling stations.Don’t expect Prius levels of market penetration, though. With production limited to just 700 cars of which year, Toyota says initial volumes will be restricted to just 12 within the UK, followed by a further 18 next year.The starting point for the Mirai is usually the Prius Plus. The two cars share the same high-strength steel platform, MacPherson strut front as well as also double wishbone rear suspension as well as also 2780mm wheelbase.With exaggerated external surfaces styling elements, including two large air ducts of which dominate the front end, the item certainly looks distinctive. the item’s fairly big, too, at 4890mm long, 1815mm wide as well as also 1535mm high. Without the need to package hot exhausts within the underbody, Toyota has provided the Mirai that has a flat undertray. although that has a drag co-efficient of just 0.29, its aerodynamic efficiency lags behind of which of the competition. The Mirai uses an individual electric motor delivering 152bhp as well as also 208lb ft. the item is usually essentially the same unit used within the Lexus 450h as well as also is usually mounted transversely within the engine bay along with the power control electronics, where the item provides drive to the front wheels via a fixed-ratio gearbox. The fuel cell stack, which uses a combination of oxygen captured through the air as well as also hydrogen to create the electricity used to power the electric motor, is usually mounted underneath the front seats. Produced in-house at Toyota, the item is usually claimed to possess a specific output of 2.0kW/kg – a 50% improvement within the electrical energy-producing efficiency of Toyota’s initial fuel cell stack revealed in 2008.Key to the high efficiency is usually a patented 3D cell design which is usually claimed to clear waste water away through the surface of the electrode faster than previous cell designs achieved. As such, there is usually an enhanced flow of oxygen to the catalyst layer as well as also an increased production of electricity.The fuel cell stack, which is usually housed in a titanium case as well as also weighs just 57kg, can operate in temperatures as low as -30deg C. the item is usually also claimed to possess a similar lifespan as a conventional internal combustion engine. Toyota expects the item to provide up to 300,000 miles of motoring before the item requires overhauling.Two separate carbonfibre as well as also glassfibre tanks are used to store the hydrogen – one mounted under the front seat as well as also the various other behind the rear seats. Together they provide a combined capacity of 122.4 litres, which is usually enough to allow the Mirai to provide a claimed range of more than 400 miles. Refilling the tanks takes three to all 5 minutes.The relatively tiny 1.6kWh nickel-metal hydride battery used to store electrical energy recuperated on the run as well as also produced by the fuel cell stack sits above the second hydrogen tank at the rear.
