The 2020 Tesla Semi delivers massive savings in energy costs, performance, efficiency and reliability.
The biggest immediate cost-advantage comes from savings in energy costs: fully loaded, the Tesla Semi consumes less than two kilowatt-hours of energy per mile and is capable of 500 miles of range at GVW and highway speed, accommodating a wide range of shipping applications given that nearly 80% of freight in the U.S. is moved less than 250 miles. Coupled with the low and stable nature of electricity prices – which average
Review: Mack’s New Anthem Truck Marks Upgrade
To test the new semi-tractor — it replaces the axle-back Pinnacle early next year — Trucks.com joined an 800-mile convoy, driving a selection of different Anthem configurations with Mack’s MP7 and MP8 engines, including the new turbocompound MP8.
The route started from the Mack Customer Center in Allentown, Pa., and ended at the new Nextran dealership in Duluth, Ga.
The Anthem, a redesign of Mack’s long-haul tractor offering, features bold new exterior styling, a new hood, roof cap and side skirts, which combine to increase the entire line’s “wow” factor.
Inside, the cab and sleeper get an all-new dash and a full stand-up cab height behind the driver’s seat in the 70-inch sleeper. New seats and new materials and up to 27 cubic feet of storage add up to a pleasing interior that Mack designed to help fleets recruit and retain drivers.
We drove the model that most over-the-road truckers will consider: the 70-inch, high-roof sleeper Anthem with the 455-horsepower, turbocompound engine option. A turbocompound engine employs a turbine to recover energy from the exhaust gases.
The test truck was pulling a loaded van trailer.
The Anthem is intended to boost Mack’s share of the over-the-road truck market with a new model and new buzz. Judging by the interest the 10-truck convoy generated from comments over the CB radio and at meal and rest stops, the Anthem achieves this well. The outgoing model has just over 2 percent and lags far behind the market-leading Freightliner Cascadia.
Mack’s engine lineup broadly parallels that of its corporate sibling Volvo, with the MP7, at 700 cubic inches, sharing the same hard parts as the 11-liter Volvo. And the 800-cubic-inch MP8 is similar in architecture to the Volvo 13 liter. That being said, the electronic controls give the different brands their own “personality.”
The turbocompound is the new-technology derivative of the MP8, with a two-stage turbocharger providing boost to the inlet charge while recovering some of the waste energy that would otherwise go up the exhaust.
This contributes an additional 50 horsepower to the engine’s output. The engine comes in two horsepower ratings, a 425 and a 455, both with peak torque extending down to 900 rpms.
All trucks were equipped with the Mack mDrive automated mechanical transmission. In fact, most of Mack highway-truck production is similarly equipped with mDrive, as this automated gearbox accounts for 80 percent of current production.

.12/kWh in the U.S. and can be significantly less for commercial and industrial users, falling to almost nothing when combined with local solar generation and storage – owners can expect to gain 0,000 or more in savings over a million miles based on fuel costs alone.
Without a trailer, the Tesla Semi achieves 0-60 mph in 5 seconds, compared to 15 seconds in a comparable diesel truck. It does 0-60 mph in 20 seconds with a full 80,000-pound load, a task that takes a diesel truck about a minute. Most notably for truck drivers and other travelers on the road, it climbs 5% grades at a steady 65 mph, whereas a diesel truck maxes out at 45 mph on a 5% grade. The Tesla Semi requires no shifting or clutching for smooth acceleration and deceleration, and its regenerative braking recovers 98% of kinetic energy to the battery, giving it a basically infinite brake life. Overall, the Semi is more responsive, covers more miles than a diesel truck in the same amount of time, and more safely integrates with passenger car traffic.
Reservations for the Tesla Semi can be made for ,000 USD per truck. Production in 2019.
