Forty percent thermal efficiency is superb. So is 133 MPGe. The air-cooled 8.8-kWh battery can be charged with the supplied cord in about five and a half house, investing in a 240-Volt EVSE cuts this to two hours. Handy for intra-day charging if bouncing form the home base. Otherwise 5.5 hours is quick enough for overnight park and charging.
