Colima → Guanajuato · Autopista 54D Colima-Guadalajara
What does it actually cost to drive from Colima, Colima, to Irapuato, Guanajuato? The hard numbers: 369 km (229 miles) of pavement primarily along Autopista 54D Colima-Guadalajara, 4h 6m behind the wheel, and roughly MXN 745.36 in fuel alone — that is 30.8 liters (8.1 gallons) of gasolina Magna at a 24.20 MXN/liter benchmark. Anyone leaving Colima, the capital colimense en la falda del Volcán de Fuego, typically carries samples, signed proposals, or service equipment to deliver in Irapuato, the capital fresera y nodo logístico intermedio del corredor del Bajío, and aims to be home the same evening. It is worth confirming whether the haul fits inside your daily hours-of-service window or whether an overnight at a midpoint hotel makes more sense. Applying the tarifa promedio de mercado mileage rate of MXN 6.50/km (MXN 10.46/mile), the gross outbound reimbursement settles at MXN 2398.50. Attach the visit purpose, client name, and plate number to the Clara receipt so the journal entry lands directly in the business-travel expense account. For the US professional driving the 369 km (229 mi) between Colima and Irapuato, reimbursement of MXN 2398.50 stays non-taxable to the employee when the employer follows an accountable plan under Treas. Reg. §1.62-2 and reimburses at or below the IRS standard mileage rate. US employers generally reimburse at the IRS standard mileage rate so the payment stays non-taxable to the employee under Pub. 463. Keep the IRS-compliant expense report (Form 1040 Schedule C, line 9) alongside the fuel receipt from any EIA-tracked retail station network pump used along the leg; Internal Revenue Service (IRS) examiners pull contemporaneous mileage logs first when auditing Schedule C unreimbursed business expenses, and the Colima→Irapuato corridor must show date, business purpose, and odometer readings.
