If you're pointing a 2025 Subaru Legacy north on Highway 49 this evening for a sunset run to Nevada City, we'll give you the straight version of what the drive asks of the car. It runs 28 miles. Nevada City sits at about 2,477 feet in elevation, while Auburn starts near 1,255 feet. So the Legacy climbs about 1,200 feet in under 35 minutes on a winding two-lane road that dips into canyon country before rising back through the pine belt. Plan around the grade and the spotty cell service, and you won't have surprises. The drive is a good one.
The Legacy's Lineartronic CVT holds the engine in its power band on the sustained climbs, and that steadiness counts for a lot in a midsize sedan. The car isn't sporty, and it doesn't pretend to be. But it stays composed and quiet, and the Subaru Symmetrical AWD keeps you planted through every sweeping corner even when late-summer dust and loose gravel sit at the road edge.
How Far Will the Tank Really Take You on This Route?
Far enough that fuel planning barely matters on this 28-mile run, though the combined rating is the figure to lean on here, because the EPA rates the 2025 Legacy with its 2.5L BOXER engine at 27 city / 35 highway / 30 combined mpg and 'highway' on that test cycle looks nothing like Highway 49 north of Auburn. Sustained grade climbing burns more fuel than flat-road cruising. Count on real-world numbers closer to the combined figure, not the highway figure, on the Auburn-to-Nevada City leg. The 2.4L turbocharged BOXER on the Sport and Touring XT trims is EPA-rated 23 city / 31 highway / 26 combined; the extra 78 horsepower feels like something on the steeper pitches, but the trade is real consumption on the climb.
The 28-mile round trip stays short enough that fuel planning is almost a non-issue. But if you're extending the drive or running up to Grass Valley first, it's worth knowing where the gauge sits before you leave, since cell service along the canyon stretches of Highway 49 is unreliable.
| Leg | Driving Character | EPA Baseline (2.5L) | Grade Reality | Planning Note |
|---|---|---|---|---|
| Auburn to just past Grass Valley Hwy junction | Multi-lane, stoplights, moderate grade | 27 mpg city | Consistent acceleration demand | Top off in Auburn if below half tank for an extended run |
| Grass Valley Hwy junction to Colfax Ave grade | Narrowing two-lane, winding, sustained climb | 30 mpg combined | Real-world closer to 26-28 mpg on grade | Enjoy the curve radius; Legacy AWD tracks well |
| Colfax Ave grade to Nevada City | Pine-lined two-lane, rolling crests, descent into town | 35 mpg hwy | Downhill assists; regen is not a factor (gas engine) | Plan for reduced cell service through canyon sections |
| Nevada City Broad Street arrival | Town driving, stop-and-go, parking search | 27 mpg city | Flat; no grade stress | Evening parking on Broad Street fills by 7 p.m. on weekends |
The Legacy's 18.5-gallon fuel tank gives you a comfortable range buffer for any foothill day-drive. At 30 mpg combined, the EPA estimates roughly 555 miles per tank. Sixty total round-trip miles barely registers.
Where Do You Stop Along Highway 49?
You've got genuine options along the way, though mostly informal ones, and the route runs through the Auburn State Recreation Area, a 42,000-acre stretch of parkland along the North and Middle Forks of the American River, dotted with pullouts and trailheads. In July, the canyon is hot and dry. Temps at river level can run 15-20 degrees warmer than Nevada City's pine-shaded streets above. The Legacy's standard dual-zone automatic climate control, offered on Premium trims and above, matters here because the temperature shifts that much in just 20 minutes of driving.
See our current Legacy inventory if you want to check trim availability before you make this drive yours.
The South Yuba River State Park sits just north of Nevada City, and it's worth the detour on a long evening. You get real terrain here, not a manicured overlook. The Legacy carries 8.0 inches of ground clearance, which is fine for the paved access roads. The car sits lower than the Outback's 8.7, so don't count on it for anything unpaved.
The Subaru Outback is worth a look if this kind of foothill driving is a weekly thing for you (higher ground clearance and more cargo room). For a one-off sunset drive to Nevada City, though, the Legacy is the better-looking car parked on Broad Street.
Plan It This Way
Keep it simple and time your run around the Grass Valley lights, because the sunset drive from Auburn to Nevada City takes about 31-35 minutes straight through, and that margin is more than enough for a golden-hour arrival up at elevation. Nevada City's historic Broad Street district is the payoff. Gold Rush-era brick storefronts sit lit by late afternoon sun, walkable and genuinely pleasant. Leave Auburn by 7:15 p.m. in late July for a golden-hour arrival at elevation.
Run through this practical checklist before you point the car north:
- [ ] Fill the tank in Auburn before heading north; gas stations thin out past the Auburn-Grass Valley strip
- [ ] Download your maps offline before departure; canyon sections of Highway 49 drop cell signal
- [ ] Set your climate control before the canyon descent; temperature swings 15+ degrees between river level and Nevada City
- [ ] If running the 2.4L turbo, expect fuel consumption noticeably above the EPA highway figure on the sustained climb
- [ ] Check Highway 49 for any Caltrans construction advisories; summer lane work is common on this corridor
- [ ] Arrive by 7 p.m. on weekends if you want Broad Street parking without circling
- [ ] Download the Caltrans QuickMap app for real-time incident alerts on the route
Does the final-year status change the math for you? It might, and that's a call worth making with clear eyes. The 2025 Legacy is the final model year, and Subaru confirmed production ended at the Lafayette, Indiana plant after the 2025 run. No 2026 will be built. If there's a Legacy on our lot, it's genuinely the end of the line for this nameplate. Some buyers find that reason enough to move quickly, while others are waiting to see what the upcoming redesign brings as a natural successor to this generation. Either way, we'd rather you know the full picture than be surprised later.
What the Legacy does on Highway 49 north, that steady, planted, reasonably efficient AWD sedan behavior, is exactly what it's been doing for foothill drivers since 2020. The final year is still the same car.

Frequently Asked Questions
Is the 2025 Legacy's fuel economy affected by the Highway 49 grade climb to Nevada City?
Yes, and more than the highway number suggests. The EPA rates the 2025 Legacy with the 2.5L BOXER at 35 mpg highway, but that number reflects flat-road, steady-speed driving. On the sustained grade from Auburn to Nevada City, roughly 1,200 feet of elevation gain over 28 miles, real-world consumption on the climb will run closer to the EPA combined figure of 30 mpg, and possibly a few points below it on steeper pitches. It's not a hardship, and the Legacy's 18.5-gallon tank gives you ample range for any foothill drive. Just don't use the highway-mpg number as your planning baseline for this route.
Does Subaru Symmetrical AWD make a real difference on this drive in dry July conditions?
Honestly, less than it does in November. On a dry summer evening, Highway 49 north of Auburn is well-paved two-lane road. AWD isn't doing active work the way it does when the road is wet or when pine needles and late-summer dust coat the corners. What it gives you is confidence through the longer, sweeping curves without your thinking about it. That said, the Legacy's AWD is standard across every trim at no upcharge, so the question is moot. You have it regardless.
Is the 2025 Legacy discontinued, and should that affect whether I buy one now?
Subaru confirmed production of the Legacy ended after the 2025 model year, and the final units came off the line at the Lafayette, Indiana plant, so no 2026 Legacy will be produced. In practice, that means remaining new inventory is finite and will not be replenished. For the right buyer, that's a clear window. You know exactly what you're getting. Parts and service support remain fully intact, and Subaru of America has confirmed ongoing parts availability. The car itself is unchanged from what earned strong safety ratings throughout this generation. For buyers who want the latest model year of something, the next generation redesign is the natural pivot point to discuss.
