2024 Subaru Solterra Premium Review: Range, Charging & Real-World Ownership

The 2024 Subaru Solterra Premium sits at an interesting crossroads in the electric SUV market. Built on the same Toyota-subaru co-developed e-TNGA platform as the bZ4X, the Solterra Premium differentiates itself with standard all-wheel drive, Subaru's trademark rugged styling, and a genuine off-road pedigree that most electric crossovers simply don't attempt. But with an EPA range that trails key competitors and a charging architecture that peaked a generation ago, is the Solterra Premium still a smart buy in 2026's crowded EV landscape?

We've spent time with the Solterra Premium to give you the exact numbers — range, charging curves, real-world efficiency, and total ownership cost — so you can decide whether Subaru's first EV earns a spot in your driveway.

Range and Efficiency: What the EPA Says vs. Reality

The 2024 Solterra Premium carries an EPA-estimated range of 227 miles on its 71.4 kWh usable battery pack (72.8 kWh total capacity). That places it squarely in the middle-lower tier of compact electric SUVs — behind the Hyundai Ioniq 5 (303 mi), the Tesla Model Y Long Range (330 mi), and the Ford Mustang Mach-E Extended Range (312 mi).

Efficiency lands at 104 MPGe combined (111 city / 97 highway) per fueleconomy.gov, translating to roughly 32 kWh per 100 miles. That's adequate but not class-leading — the Ioniq 5 achieves 114 MPGe combined, and the Model Y hits 122 MPGe.

Battery Chemistry, Capacity, and Longevity

The Solterra Premium uses a lithium-ion NMC (nickel manganese cobalt) battery with 71.4 kWh of usable capacity. NMC chemistry offers higher energy density than LFP (lithium iron phosphate), which is why Subaru can package this pack in a relatively compact floor layout while still offering standard AWD.

NMC packs do carry a slightly faster degradation profile than LFP over thousands of charge cycles, but Subaru backs the battery with an industry-standard warranty: 8 years or 100,000 miles (whichever comes first) against capacity loss below 70%. In practice, most NMC packs from this generation lose roughly 8–12% capacity over the first 100,000 miles based on fleet data from similar e-TNGA vehicles — meaning you'd still have approximately 200 miles of range at that mileage mark.

Charging Speed: The Solterra's Biggest Compromise

Here's where the Solterra Premium reveals its most significant limitation. The DC fast-charging architecture tops out at 100 kW peak — and that peak is short-lived. The actual charge curve tells the real story:

The 10–80% charge takes approximately 56 minutes on a 150+ kW DC fast charger — nearly double the time of competitors like the Ioniq 5 (18 minutes at 240 kW) or the Kia EV6 (18 minutes at 240 kW). The Solterra's charge curve tapers aggressively after 40% state of charge (SoC), dropping below 50 kW by the time you reach 65%. This means road-trip charging stops will be noticeably longer.

For home Level 2 charging, the onboard charger accepts up to 6.6 kW. With a standard 32-amp Level 2 wall connector (like a ChargePoint Home Flex or Tesla Wall Connector set to 32A), you'll add roughly 22 miles of range per hour — enough to replenish a full day's commute overnight. A full 0–100% charge takes about 11 hours.

The Solterra uses the CCS1 connector for DC fast charging and a J1772 inlet for Level 2. Subaru has not announced a transition to the NACS (Tesla) connector for the 2024 model year, so you'll need a CCS adapter to access Tesla Superchargers — and not all Supercharger stalls support CCS yet.

Performance and Driving Dynamics

Every 2024 Solterra comes with Subaru's dual-motor Symmetrical All-Wheel Drive — no single-motor, front-wheel-drive variant exists. The Premium trim produces 215 horsepower and 248 lb-ft of torque, delivering a 0–60 mph time of approximately 6.5 seconds. That's adequate for merging and passing, though it trails the Mach-E GT (3.5s) and Model Y Performance (3.5s) by a wide margin.

Where the Solterra earns its Subaru badge is off-pavement. With 8.3 inches of ground clearance and Subaru's X-MODE traction management system, the Solterra handles dirt roads, snow, and light trail duty with more confidence than nearly any other electric crossover. The 220 mm water fording depth and Hill Descent Control aren't marketing gimmicks — they're genuinely useful for owners who take the Subaru lifestyle seriously.

The ride quality is compliant and well-damped, though the steering lacks the precision of the Ioniq 5 or the Model Y. Regenerative braking offers multiple levels adjustable via paddle shifters, but the Solterra does not offer true one-pedal driving — you'll still need the friction brake for complete stops.

Pricing, Trims, and Federal Tax Credit

The 2024 Solterra is available in three trims, all with standard AWD:

*Effective price assumes full $7,500 §30D credit eligibility. Actual credit varies by buyer.

Does the 2024 Solterra qualify for the federal EV tax credit? Yes — but with critical caveats. Under IRS §30D rules, the full $7,500 credit requires meeting both critical-mineral sourcing and battery-component manufacturing thresholds, which shift annually. The Solterra's battery is manufactured in Japan by Panasonic, and its critical-mineral supply chain compliance has fluctuated. Always verify current eligibility on the IRS clean vehicle credit page before purchasing.

Additional eligibility requirements include:

• MSRP cap: SUVs must have an MSRP at or below $80,000 (all Solterra trims qualify)
• Buyer income cap: AGI must not exceed $150,000 (single), $225,000 (head of household), or $300,000 (joint)
• Point-of-sale transfer: As of 2024, you can transfer the credit to the dealer for an immediate price reduction at purchase
• Battery sourcing: Verify current-year critical-mineral and component requirements on irs.gov

Interior, Technology, and Cargo

The Solterra Premium's interior is functional but not class-leading in material quality. The 12.3-inch touchscreen (shared with the Toyota bZ4X on higher trims; the Premium uses an 8-inch display) runs Subaru's Starlink infotainment system with wireless Apple CarPlay and Android Auto. The system is responsive enough, though the menu structure isn't as intuitive as Hyundai's or Tesla's interface.

Standard driver-assistance tech includes Subaru EyeSight 4.0 with adaptive cruise control, lane-centering assist, pre-collision braking, and evasive steering assist. This is a SAE Level 2 driver-assistance system — it does not enable hands-free or self-driving operation. You must keep your hands on the wheel and eyes on the road at all times. EyeSight performs competently on highways but lacks the lane-change-on-indicator functionality of GM's Super Cruise or Ford's BlueCruise.

Cargo space measures 23.8 cubic feet behind the rear seats and 63.5 cubic feet with the 60/40 split rear seats folded. That's competitive with the Ioniq 5 (27.2 / 59.3 cu ft) but notably less than the Model Y (30.2 / 76.2 cu ft). Rear-seat passengers get 35.7 inches of legroom, which is adequate for adults but not generous. There is no front trunk (frunk).

Pros, Cons, and Who Should Buy

Competitive Comparison

The Solterra Premium competes directly with the Hyundai Ioniq 5, Kia EV6, Ford Mustang Mach-E, and Tesla Model Y. Here's how the numbers stack up:

The Solterra wins on ground clearance and starting price (before credits, the gap narrows). The Ioniq 5 and Model Y dominate on range and charging speed — the two metrics that most influence daily EV satisfaction.
