**Cross-Country Trip Example** (NYC to LA, 2,800 miles, 8 stops):.

**Route**: New York → Cleveland → Chicago → Denver → Las Vegas → Los Angeles.

**Fuel Calculation**: - **Highway miles**: 2,400 miles (28 MPG) = 85.7 gallons - **City miles** (8 stops × 50 mi): 400 miles (22 MPG) = 18.2 gallons - **Detours** (20% of 2,800): 560 miles (25 MPG) = 22.4 gallons - **Idle fuel** (8 stops × 1 hr): 8 hours × 0.3 = 2.4 gallons - **Total fuel**: **128.7 gallons**.

**Cost by Region**: - **New York to Chicago** (900 mi, 32 gal): $4.00/gal avg = **$128** - **Chicago to Denver** (1,000 mi, 36 gal): $3.30/gal avg = **$119** - **Denver to LA** (1,000 mi, 36 gal): $4.50/gal avg = **$162** - **Total trip cost**: **$409** (vs $332 if constant $3.50/gal).

**Vehicle Type Comparison** (1,000-mile trip with 5 stops):.

| Vehicle Type | Highway MPG | City MPG | Total Gallons | Cost @ $3.50/gal | Cost Difference | |--------------|-------------|----------|---------------|------------------|-----------------| | **Compact Car** (Honda Civic) | 36 MPG | 30 MPG | 37 gal | **$130** | Baseline | | **Sedan** (Toyota Camry) | 32 MPG | 25 MPG | 42 gal | **$147** | +$17 | | **Midsize SUV** (Honda CR-V) | 28 MPG | 22 MPG | 47 gal | **$165** | +$35 | | **Full-Size SUV** (Chevy Tahoe) | 20 MPG | 15 MPG | 66 gal | **$231** | +$101 | | **Pickup Truck** (Ford F-150) | 22 MPG | 17 MPG | 60 gal | **$210** | +$80 | | **Hybrid** (Toyota Prius) | 50 MPG | 48 MPG | 25 gal | **$88** | -$42 | | **Electric** (Tesla Model 3) | N/A (kWh) | N/A | 300 kWh | **$45** @ $0.15/kWh | -$85 |.

**Stop Optimization Strategies**:.

**1.

Minimize City Driving**: - **Choose stops on highway exits** (not downtown): Save 15-30 miles city driving per stop - **Gas up before entering cities**: Highway gas stations are 10-30¢/gal cheaper - **Example**: 5 suburban stops vs 5 downtown stops = Save $15-25.

**2.

Combine Stops**: - **Cluster activities** (gas + restroom + food in one stop): Save 2-3 stops = $10-20 - **Overnight near attractions**: Reduce next-day detour mileage.

**3.

Use Cruise Control**: - **Highway segments**: Maintain steady speed (55-65 mph optimal MPG) - **Fuel savings**: 7-14% vs variable speed = $9-18 on 1,000-mi trip.

**4.

Plan Route for Fuel Prices**: - **GasBuddy app**: Shows real-time prices along route - **Fill up in low-price states** (Texas, Oklahoma): Save $0.50-1.00/gal = $20-40 per tank - **Avoid tourist traps**: Highway rest stop gas 20-50¢/gal premium.

**5.

Reduce Idle Time**: - **Turn off engine** when stopped >30 seconds: Save 0.1 gal/stop - **Pre-cool cabin before stops** (run AC while driving): Avoid idling for AC.

**Elevation/Terrain Impact**:.

**Mountain Routes** (I-70 through Rockies): - **Uphill**: MPG drops 30-50% (28 MPG → 14-20 MPG) - **Downhill**: MPG improves 20-30% (28 MPG → 34-36 MPG) - **Net effect**: 15-20% worse MPG overall - **Example**: Denver to Vail (100 mi, 8,000 ft elevation gain): - **Flat road**: 100 ÷ 28 = 3.6 gallons - **Mountain**: 100 ÷ 22 = **4.5 gallons** (+25% fuel).

**Weather Impact**:.

**Headwinds/Crosswinds**: - **10-15 mph headwind**: -5% MPG - **20-30 mph headwind**: -10-15% MPG - **Example**: 500 mi in 20 mph headwind = Extra 2-3 gallons ($7-10).

**Extreme Temperatures**: - **AC usage** (95°F+): -10-20% MPG - **Heater** (cold <32°F): -5-10% MPG (engine takes longer to warm) - **Example**: Summer desert crossing (500 mi, AC on high) = Extra 3-5 gallons ($10-18).

**Load/Cargo Impact**:.

**Roof Cargo** (cargo box, bikes): - **Aerodynamic drag**: -10-25% MPG - **Example**: 1,000 mi with roof box = Extra 5-10 gallons ($18-35).

**Heavy Load** (luggage, passengers): - **100 lbs extra weight**: -1-2% MPG - **500 lbs extra** (4 passengers + luggage): -5-10% MPG - **Example**: Family road trip (500 lbs load) = Extra 2-4 gallons ($7-14).

**Real-World Trip Budget** (1,000 mi, 5 stops, 2025):.

**Conservative Estimate** (compact sedan, efficient driving): - **Base fuel**: 37 gallons × $3.50 = $130 - **Stop penalty** (15% detour): +$20 - **City driving** (5 stops): +$15 - **Idle fuel**: +$5 - **Total**: **$170**.

**Realistic Estimate** (midsize SUV, normal driving): - **Base fuel**: 47 gallons × $3.50 = $165 - **Stop penalty** (25% detour): +$40 - **City driving** (5 stops): +$25 - **Idle fuel**: +$8 - **Load/AC**: +$12 - **Total**: **$250**.

**Worst-Case** (full-size SUV, inefficient route, CA gas prices): - **Base fuel**: 66 gallons × $5.20 = $343 - **Stop penalty** (40% detour): +$137 - **City driving** (5 stops): +$52 - **Mountain routes**: +$35 - **Idle fuel**: +$15 - **Total**: **$582**.

**Fuel Cost Comparison vs Flying**:.

**NYC to Miami** (1,280 miles, 4 stops): - **Driving** (sedan): $225 gas + $300 hotels = **$525 total** - **Flying** (1 person): $150 flight + $80 airport transfer = **$230 total** - **Flying** (family of 4): $600 flights + $120 transfer = **$720 total** - **Break-even**: 3+ passengers make driving cheaper.
