If you constantly run
LONG distance at
highway MOST OF THE TIME with
speed ABOVE 110km/h, then turbo might be the better option.
However there is a misleading condition when ppl say when using mostly highway, turbo better becoz turbo is better for highway run ONLY with the ABOVE conditions.
However if you spend a lot of time in City as well AND using only short distance highway like Klang Valley's Kesas, NVKE (from Klang to Damansara, etc), and run mostly at relaxed driving speed of 110km/h and below, by all means RS with it's full specs are the best. Occasional speed of 140km/h ok lar but when relaxed casual drive of 110km/h below, RS is better coz it will keep switch to EV, then engine turn on to charge....then switch back to EV. Generally motor drive and ecvt smooth acceleration all the way, very fuel efficient with strong torque at that speed and below.
If you concentrate only on fuel savings and efficiency AND
long distance high speed highway run, then RS tak berbaloi.
IMO, when you buy Honda eHev, half is about fuel efficiency, another half is the semi EV driving experience you get with Honda eHev.
Honda eHev hybrid setup although are similar to Toyota Synergy in fuel efficiency, are quite drastically different in driving experience.
While Toyota Hybrid mostly engage motor (full EV) below 40km/h, it is mostly an engine assisted by motor drive with the very efficient planetary gear to switch between engine and motor. After 40km/h, it will generally be engine engaging the wheel assisted by motor with with complex switch managed by planetary gear. Top notch in fuel efficiency and much lesser gear maintenance required for the hybrid system vs Honda eHev.
Our eHev will mostly engage motor to wheel below 110km/h. So technically you are getting full EV driving experience at low and mid torque with motor directly engaged to the wheel below 110km/h. Engine are mostly there to assist charging the battery and motors especially during harder acceleration. It is only when you go above 110km/h, the engine will directly clutch in to the wheel. (Note : I believe below 110km/h, occassionally engine will also clutch in when going at higher end limit there and doing hard acceleration).
Of course it can't compare to pure EV, Honda seems to control the acceleration to gradual acceleration increment rather than Tesla G-Force type of full acceleration. Engine noise and vibration also makes it uncomparable to pure silent EV drive BUT the smoothness of eCVT acceleration (only make possible as with electrical motor), the torque strength with motor engaged to wheel is for me, way ahead in comfort vs normal CVT with engine acceleration. The micro vibration of motor even with the noiser engine (much muted in CRV and Civic) is much better than Turbo CRV.
You have to drive RS for at least 15 minutes and then immediately drive turbo CRV to feel the difference in vibration tho...Just like selecting LED TV, lower cost TV ok in resolution BUT when you put it side by side with higher end wan, then you straight away see the drastic quality difference between 2 of them but when use alone, still very good wan.
Value for money, we can't deny Turbo CRV is better with the drastic price increase of RS setup but you can't put monetary value on the semi EV experience that you can get with RS eHev. Just my own 2 cents.
Based on my experience, sometimes the EV mode engaged when driving more than 110kmh. I think sometime at 120kmh also the EV mode will engage. Most of the time it will happen when i maintain constant speed cruising. but definitely it will not last long compared to low speed cruising.
