As many owners found out the hard way, though, not keeping a steady eye on maintenance and oil changes proved costly, as engine sludge build up sent a number of these Japanese engines to an early grave. If engine sludge didn’t affect the engine, another killer proved to be head gasket failures with cracks in the aluminum heads that caused overheating issues.
Being the only dedicated subcompact hybrid vehicle on the market, the Kia Niro deserves to be in consideration for the best hybrid SUV 2019 is bringing our way. This affordable crossover started out as a conventional hybrid, but the plug-in version soon ensued. Both versions sport the same 1.6L inline-four engine and an electric motor. Moreover, both models generate the same 139 net horsepower.
The all-electric crossover that was first presented at the 2015 Frankfurt Auto Show will be powered by three electric motors and a 95 kWh battery pack. This setup should be good enough for 429 net horsepower. Since the Volkswagen Group is planning on producing a number of global volume all-electric models, I wouldn’t exclude at least one more battery capacity to be offered under the Audi badge.
Most of the time everyone wants to talk about the GOATs (Greatest of All Time) and debate which engine they’d swap into their favorite ride if money was no object. Would it be a Nissan RB-series from the famed Skyline GT-R? What about the Toyota 2JZ from the iconic Supra? Both are probably on everyone’s top engines list, but the elephant in the room that no one wants to talk about are the engines that couldn’t dream of showing up on a GOAT list. These are the engines that are debated as the worst Japanese engines of all time because of poor engineering.
