2024 Subaru Solterra Range, Charging & Real-World Review

Quick Verdict: A Genuine Subaru, But an Underwhelming EV

The 2024 Subaru Solterra is the brand's first dedicated battery-electric vehicle, built on the e-TGBL platform co-developed with Toyota (its twin is the bZ4X). It delivers standard all-wheel drive, 8.3 inches of ground clearance, and the X-MODE traction system that loyal Subaru buyers expect. But as an EV in a segment now stacked with 300+ mile competitors, the Solterra's modest range and slow DC charging are hard to overlook — even after a significant charging speed improvement over the 2023 model year.

For 2024, Subaru raised the DC fast-charging ceiling from roughly 100 kW to approximately 130 kW on higher trims, added a battery preconditioning feature, and kept pricing competitive. The question is whether Subaru's off-road credibility and standard AWD are enough to offset a 228-mile EPA range ceiling and a charging curve that still trails the Hyundai Ioniq 5 and Kia EV6 by a wide margin.

Range, Efficiency & the Real-World Reality Check

The Solterra carries a 71.4 kWh usable lithium-ion battery (approximately 72.8 kWh gross) using NMC (nickel-manganese-cobalt) cell chemistry supplied by CATL and Panasonic, depending on the production batch. This is a modestly sized pack for a 4,365-pound crossover, and it shows in the efficiency numbers.

According to fueleconomy.gov, the 2024 Solterra achieves:

The efficiency penalty of the larger 20-inch wheels and standard AWD is real. Competitors like the Hyundai Ioniq 5 (114 MPGe combined on SEL AWD with a 77.4 kWh pack and 260-mile range) extract more miles per kilowatt-hour from a similar footprint. The Solterra's boxy shape, heavy curb weight, and all-terrain tire compound (on certain trims) all contribute to its thirstier consumption.

Charging: Improved for 2024, Still a Weak Point

Charging speed was the 2023 Solterra's most criticized flaw, and while Subaru made meaningful upgrades for 2024, the results still place the Solterra behind segment leaders. Here's what you need to know, distinguishing between kW (the rate of power delivery — think of it as how fast water flows through a hose) and kWh (the total energy stored in the battery — the size of the tank).

*10–80% time is under ideal conditions with a preconditioned battery and a capable 150+ kW CCS charger. Real-world sessions on Electrify America or EVgo often average 80–100 kW sustained, stretching the 10–80% window closer to 40–45 minutes.

The 2024 model year brought a battery preconditioning feature — accessible through the infotainment system — that warms the pack before a DC fast-charging session. This matters enormously: without preconditioning, cold-soaked batteries can see peak rates cut in half. Always activate preconditioning when navigating to a charger.

However, the charging curve still tapers aggressively past 80% state of charge (SoC). The last 20% can take as long as the first 70%, which is typical of NMC chemistry but more pronounced here than in the Ioniq 5's 800-volt architecture (which sustains high rates longer and achieves 10–80% in roughly 18 minutes at a 350 kW charger).

For home Level 2 charging, the 7.2 kW onboard charger is adequate but not generous. A full 0–100% session takes about 9.5 hours, meaning most owners charging overnight from 20% will wake up to a full battery — but those with shorter overnight windows (e.g., arriving home at 11 PM and leaving at 6 AM) may not fully replenish after a heavy driving day.

Performance, Drivetrain & the Subaru DNA

The dual-motor AWD system is where the Solterra earns its Subaru badge. X-MODE is standard, offering Snow/Dirt and Deep Snow/Mud settings that modulate torque distribution and traction control for low-grip surfaces. In our experience on gravel forest roads and light snow, the Solterra's AWD system is genuinely capable — better than most crossover EVs that simply apportion torque front-to-rear without terrain logic.

The 6.5-second 0–60 time is adequate for merging and passing but won't excite anyone coming from a Tesla Model Y Performance (3.5 seconds) or even the Ioniq 5 AWD (5.0 seconds). The Solterra prioritizes low-speed tractability and off-road crawl control over straight-line speed.

One notable omission: the Solterra is not rated for towing. For buyers who need to pull a small trailer or bike rack with a hitch receiver, this is a dealbreaker. The Hyundai Ioniq 5 and Kia EV6 both offer a 1,650-pound tow rating on AWD trims.

Interior, Cargo & Daily Practicality

The Solterra's cabin is functional and durable rather than luxurious. Hard plastics appear on the lower door panels and center console — a Subaru tradition — but the upper dash uses soft-touch materials and the overall build quality is solid.

The absence of a frunk is a missed opportunity — many competitors offer 0.8–2.0 cu ft of under-hood storage for charging cables. The 23.8 cu ft rear cargo area is competitive with the Toyota bZ4X (identical platform) but trails the Ioniq 5 (27.2 cu ft) and Model Y (30.2 cu ft). Rear legroom at 35.7 inches is tight for taller passengers on long trips.

The 12.3-inch touchscreen infotainment system (standard on Limited and Touring; 8.0-inch on Premium) supports wireless Apple CarPlay and Android Auto. Subaru's latest Starlink connected services include remote charging status, preconditioning scheduling, and OTA (over-the-air) update capability. The digital gauge cluster sits high on the dash, positioned to reduce eye movement — similar to Peugeot's i-Cockpit approach.

Pricing, Trims & Federal Tax Credit Eligibility

*Prices include destination charge. Tax credit eligibility depends on buyer income, battery sourcing, and MSRP caps. See details below.

The 2024 Solterra qualifies for the IRS §30D federal tax credit, but eligibility is not automatic for every buyer. Here's the checklist:

• MSRP Cap: The Solterra is classified as an SUV/crossover, so the MSRP cap is $80,000. All trims clear this easily.
• Buyer Income Cap: Modified adjusted gross income (MAGI) must not exceed $150,000 (single), $225,000 (head of household), or $300,000 (married filing jointly).
• Battery Sourcing: The credit is split into two halves — $3,750 for critical minerals and $3,750 for battery component assembly. As of the 2024 model year, the Solterra qualifies for the full $7,500 based on Subaru's supply chain disclosures, but sourcing rules tighten annually. Verify current eligibility at the point of sale.
• Point-of-Sale Transfer: Beginning in 2024, buyers can transfer the credit to the dealer at purchase, reducing the purchase price directly rather than waiting to claim it on their tax return. This requires the dealer to be registered with the IRS Energy Credits portal.

Consult a tax professional for your specific situation — the credit is non-refundable, meaning you need sufficient tax liability to benefit from it if you don't use the point-of-sale transfer option.

Battery Warranty & Long-Term Ownership

Subaru provides a battery warranty of 8 years / 100,000 miles, guaranteeing that the high-voltage battery will retain at least 70% of its original capacity during that period. The powertrain warranty is 5 years / 60,000 miles, and the limited vehicle warranty is 3 years / 36,000 miles.

NMC batteries in this class typically degrade 10–15% over the first 100,000 miles under normal use patterns. Subaru's 70% retention threshold is industry-standard but less generous than Hyundai's 8 years / 100,000 miles at 70% (identical terms) or Tesla's 8 years / 120,000 miles at 70% for Model Y. The Solterra's smaller battery means each percentage point of degradation translates to fewer lost miles — a 15% loss on a 228-mile range leaves roughly 194 miles, which is still livable for most commutes.

Replacement cost for the entire battery pack is estimated at $12,000–$18,000 out of warranty, though individual module replacement may be possible at lower cost depending on the failure mode.

How It Compares: Solterra vs. the Competition

The Solterra wins on ground clearance and standard AWD pricing — it's the cheapest way to get dual-motor all-wheel drive in this group. It also wins on off-road capability thanks to X-MODE. But it loses decisively on range, charging speed, and performance.

Safety & Driver Assistance

Subaru's EyeSight suite is standard across all trims, including adaptive cruise control with lane centering, pre-collision braking, lane departure warning, and lead vehicle start alert. This is an SAE Level 2 driver-assistance system — meaning the driver must remain fully engaged with hands on the wheel and eyes on the road at all times. It is not autonomous driving.

The Insurance Institute for Highway Safety (IIHS) awarded the Solterra (tested as the Toyota bZ4X twin) good ratings in most crashworthiness categories. The NHTSA has also rated the platform. Always verify the latest model-year scores, as testing protocols evolve.

Pros, Cons & Who Should Buy

Who it's best for: The 2024 Solterra fits Subaru loyalists who live in snow-belt states or rural areas with unpaved roads, have reliable home Level 2 charging, and whose daily driving stays under 120 miles. It's a commuter and weekend-adventure vehicle — not a road-trip machine.

Who should look elsewhere: Frequent highway travelers, those without home charging access (the Solterra's slow DC charging makes public-only ownership painful), and anyone who needs towing or maximum cargo room should cross-shop the Ioniq 5, EV6, or Model Y.
