Background:
I have two homes, one in Phoenix AZ, and one in Sausalito CA.
Before my (now) 2nd home in Sausalito, I had a 2nd home in Rancho Palos Verdes (LA suburb) when my son was going to school at USC.
I regularly drove the Phoenix to LA route (400 miles, door-to-door) and now, I drive the Phoenix to Sausalito (~780 miles, door-to-door) route.
I am a strong EV advocate. My home in Phoenix has been 100% solar-powered and wired for EV charging since 2008. Sadly, no pure EV was worth buying until the 2020s. I had a gas hybrid (2017 Lexus RX450H), and a 2019 Honda Clarity (PHEV)—now my son’s car. Currently, I drive a 2022 Lucid AGT and a 2023 Rivian R1S.
I want to share my perspectives about taking long road trips in a hybrid, a PHEV, and two different EVs. Nothing profound. Just some real-life experience and numbers for long road trips.
Framing:
I don’t intend to get into debates with anyone about the efficiency (miles/kWh) of EVs and whether it is related to the square or cube of the speed etc., drag coefficients, elevations, etc., etc.. Enough has already been said by many forum participants. Mostly, I loosely follow the speed limit, between 70-80mph on I10 and I5. In short, if you drive fast, your efficiency will be (substantially) lower than EPA and what you wished for. There are a lot of nuances than just the drag factor and the speed. That’s just life! Suck it up!
In Perspective:
- I drove my Lexus on many trips to LA and to Sausalito. In short, the Lexus performed flawlessly over a 6-year period. It gets ~28-29 miles/gallon. Its driver assist functions (lane-keep, adaptive cruise control, etc.) are on par with all the other cars, even though the Lexus is 5-6 years older than the Lucid and the Rivian (see below). I had ZERO problems with the Lexus over a 6+ year ownership. It was a quality car! The trip from Phoenix to LA takes ~6hrs, non-rush hour, 1X gas refill. Trip from Phoenix to Sausalito takes ~11hrs (no traffic), 2X refill. Cost of gas ~$120-140 (@$4.50/gallon avg) for the Phoenix to Sausalito trip, depending on the prevailing gas price.
- The Honda Clarity is the best-balanced car if you want EV economy/convenience and no anxiety on long drives. It gets 45+ EV miles (rated @47 miles) range when fully charged. I can get around town on EV-only and never needed any gas until I got on the road between LA and Phoenix. There, I used the “mixed mode” with EV and gas. It gives a good balance between power and economy. Trips between Phoenix and LA take 6hr, 2X refill (The Clarity only has a 7-gallon gas tank). The cost of gas is <$55 for the Phoenix to LA trip. I love this car!
- I bought the Lucid AGT (19” wheels) in Nov 2022, mostly because of the advertised range (EPA range rated at 516 miles). It is the longest-range EV around. In reality, it barely covers the 400-mile distance between Phoenix and LA. True, there are elevation changes (e.g., San Bernadino Mts, etc.) and highway speed (70-80 mph) that wreak havoc on your EPA range. On over 7,000 miles of driving the Lucid, the efficiency is ~3.6 miles/kWh. Pure highway driving (70-80 mph) is ~2.9-3.0 miles/kWh. The cost of charging for the Phoenix to Sausalito trip is ~$150-$160 with Electrify America (@56c/kWh). Free, if you have the free charging.
On the Phoenix to Sausalito trips (780 miles), it takes ~12 hrs. The Lucid can make it with 2 charging stops. But you need to plan carefully. I arrived in Sausalito (from Phoenix) with 2 charging stops, with <5% SoC upon arrival! One good thing about the Lucid is its fast charging, unless your charging rate is limited by Electrify America throttling, and it happens often!
The ground clearance of the Lucid is incredibly low. That’s how they get the drag coefficient down. Mechanically, this car is a thrill to drive. The interior is comfortable. But you must be extremely careful not to go over bumps fast or park too close to the curb! The infotainment and SW are sub-par! The navigation is barely functional and laggy. I must resort to my phone navigation on several occasions.
- The Rivian is built like a tank! It is rugged and rides high. It is reasonably comfortable, though not luxurious. With the large pack (battery), it is rated at ~321miles (road tires, quad motor). You can squeeze out another 15 miles or so using Conserve mode (FWD only). From my experience and other Rivian owners’ reports, the efficiency is close to 2.3 miles/kWh, higher than the 2.0 miles/kWh claimed by Rivian. It can pull 7,000 lbs and carry a lot of stuff! It rides high and can handle rough roads. The 3rd row seats are not that bad, though I won’t ride the 3rd row for a 13-hour trip. The SW and infotainment system is superior to that in Lucid’s. The navigation is excellent, the destination search is very informative and far better than Lucid’s.
If your trips are less than 550 miles, you can do it with 2 charges. But my Phoenix to Sausalito trip requires 3 (or even 4) charging stops. But if you like rough roads and 4-wheeling, Rivian is the only (EV) way to go!
Rivian has its own “Adventure” charging network. It used to be free (ended Nov 2023). Rivian now charges a uniform 36 cents/kWh. These DC chargers are rated at 300kW. My experience is, that every single one worked, and they don’t throttle, far better than Electrify America! And Rivian charger’s rates (36 cents/kWh) is MUCH cheaper than Electrify America (and Tesla)! On paper, the Rivian does not charge as fast as the Lucid per the charging specs. In reality, the Lucid does charge faster, but the difference in actual charging time is not as big as the specs suggest since the Lucid’s peak charging rate is only relevant over a small SoC range (e.g., from 20% to say 40%). Nevertheless, taking the Rivian on the 780-mile journey will result in an additional stop (or two) and 35 minutes or more. The cost of charging is ~$130-135 (@36c/kWh) if you use all Rivian Adventure charging stations.
In conclusion, if I only have one car and I need to do long-distance driving, I’d opt for a PHEV. The Lucid AGT’s range and fast charging are pluses for long road trips and fun to drive. It saves 1 to 2 charging stops and ~1+hr of travel time on a 780mi trip. But the Lucid has the highest fuel cost (if you must pay for it). The navigation system is quirky, laggy, and almost useless. The Rivian R1S is roomy and rugged. Best for family/dogs, camping, 4-wheeling, and hauling thing. Its range and efficiency are not as good as the AGT. However, the Rivian Adventure chargers are great and about 30-45% cheaper than Electrify America and Tesla chargers. According to Rivian, its Adventure Charging Stations use renewable energy such as solar and wind.
Apologies for the long rambling post. To each his own!
