I've tested the Touring Sports on both engines. The 1.8 is a quite good car, I'd buy it as it is the most proved hybrid powertrain on the market, has been continuously improved over the years, and is very frugal. But... I wanted to try the new 2.0...
I had to feel the new generation of engines that will fit all new Toyota and Lexus models. For the ones that don't know, the M20A-FXS Dynamic Force engine is the second of a family of engines regarded by Toyota as the new and best ever generation of ICE for both conventional and hybrid powertrains. The 2.0 powers the Corolla HB and Touring Sports and the Lexus UX 250. It's older 2.5l brother, the M25A-FXS, powers the Camry, RAV 4, IS 300h, ES 300h, NX 300h and RC 300h. They're high output and high efficiency engines, with on the 2.0, 54kW/l and thermal efficiency of 41% (for HV, 63kW/l and 40% for conventional powertrains) and on the 2.5, 52kW/l and thermal efficiency of 41% (for HV, 61kW/l and 40% for conventional powertrains). It's quite remarkable, technically, at least on paper, that both high efficiency and high output can be labelled on the same engine, as we're used to get either one or the other.
On top of the new engine, the 2.0 version get's the new Direct-shift CVT with the launch gear that promises shorter shift speed and higher fuel efficiency. And I'll start from here: it's great! The car answered any stronger move of my right foot with a immediate rev increase (from about 2.000 to 3.000) and delivering the torque and power needed to perform an effortless acceleration, with a reaction that it's at least equivalent of my Corolla Verso's 136hp and 310Nm 2.2 D-4D. Not bad at all for a fuel efficient hybrid! On a slight up hill wet street, starting from full stop with a stronger push of the accelerator, taught me that if I didn't want the VSC/ASR to come into action, I should have been more gentle... The test drive was... too short! The car feels smoother and more quite with this engine, reacting very well for a long station wagon with chassis handling well the increased torque and power. I tend to drive more on the highway than on city so I've decided to pay the engine premium and ordered the 2.0 version. For anyone that calls hybrids dull, test this new Corolla and change your perspective...
