Freienbach Switzerland, 10 May 2021 – Briggs & Stratton launched its Vanguard® V-Twin 40 gross HP* (29.9 gross kW) petrol engine, expanding its EFI range. Featuring Electronic Fuel Injection (EFI) and Electronic Throttle Control (ETC) technologies, it delivers maximum power with increased torque; easy, all-weather starting; and optimal load acceptance. The result is a quieter and more cost-effective alternative to diesel power for inner city construction and forestry applications.

The new V-Twin 40 gross HP* (29.9 gross kW) petrol engine is the second, and most powerful, Vanguard Big Block engine to combine EFI and ETC. Both this engine, and the earlier 23 gross HP*, address many of the concerns of the European markets regarding the use of smaller diesel engines: in particular, high noise and emission levels, and total cost of ownership.

The advanced EFI system ensures more usable power from the same block, increasing the power-to-weight ratio while reducing engine weight, compared to a diesel alternative. This enables OEMs to build smaller, lighter, and more maneuverable equipment, which, in turn, helps reduce CO2 when transporting it from site to site.

With integrated EFI intelligence, the engines can be operated in remote or unmanned equipment. Using Vanguard’s in-house diagnostics software, technicians can plug into the ECU and rapidly identify and fix any issues. Productivity, equipment uptime and ROI are increased, while total cost of ownership is reduced.

"The new Vanguard 40HP EFI engine has been developed based on market needs,” says Paul Bramhall, Director Marketing EMEA - Engines & Power. “Our customers have been looking for an engine that delivers more power without additional weight, to achieve the optimal power-to-weight ratio - particularly for weight-sensitive applications. ETC technology provides a smoother and more consistent performance as more load is applied. And by combining EFI and ETC, we deliver an efficient alternative to diesel for a wide variety of applications."

The Stage V-compliant engines do not require expensive after treatment filter systems or Diesel Particle Filters (DPF), further reducing upfront capital costs for equipment owners and rental companies. Lifespan is maximized thanks to the cyclonic air cleaner, which protects the engines under dirty and dusty conditions, as well as cast-iron cylinder sleeves and dual ball bearings. The engines come standard with a 3-year commercial warranty.

The unique combination of technologies and design makes Vanguard’s V-Twin 40 gross HP* engines a sound investment for both equipment owners and rental companies, and a perfect power option for remote operational machinery and inner city applications such as utility vehicles, woodchippers and smaller construction equipment.


*All power levels are stated gross kW (HP) at 3’600 rpm per SAE J1940.
