The toolkit
Multi-input tools that show their working, never a black box.
Tyre Size & Speedo Error
Compare two tyre sizes: speedometer error, diameter change, revs/mile and ride height.
● Live nowTow-Car Matcher
Kerb weight vs caravan MTPLM, the 85% guideline, noseweight, gross train weight and UK licence rules.
● Live nowEV Charging Time & Cost
Battery, charger and tariff → charge time, cost and cost-per-mile vs petrol.
● Live nowJourney Fuel Cost
Distance, MPG and pump price → trip cost, cost per mile, annual commute and car-vs-car comparison.
● Live nowGear Ratio & Speed
Final drive, gearing and tyre size → speed at RPM, cruise revs and top speed, with a live gearing chart.
● Live nowCar Running Cost
Depreciation, fuel, insurance, tax and servicing → the true all-in cost per mile and per year.
● Live nowWhy MotorBench?
Tools that actually compute, not just look up a number. Anyone can tell you a single figure. The questions that matter ("will these tyres throw my speedo out?", "can my car legally tow this caravan?", "is the EV really cheaper per mile than my petrol?") need real, multi-input working-out. That's what we build.
Every tool shows its method, every estimate carries an honest caveat, and there's never a sign-up wall to get an answer.
