Global leader in complex sand castings Grainger and Worrall have announced that they’ve entered the race for the fastest supercar, with their GW Speed Model 88.

The car boasts an incredible 3000 bhp, as well as some innovative design features. It’s an amazing achievement, highlighting just how far casting technology and innovative engineering can support the development of the fastest (and lightest) supercars.



The GW Speed Model 88

Recently, there has been much online discussion (and drag race challenges) about just which is faster between the Tesla Model S Plaid and Bugatti Chiron. The Tesla Model S Plaid with its 1,020 peak horsepower and 1,420nm of torque, covers zero-to-60mph in just 1.99 seconds, beating the Bugatti Chiron which still does zero-to-60mph in 2.3 seconds. The Chiron's 1,500 bhp engine and top speed of 261 mph comes into its own with rolling 50/rolling 60 tests, comfortably beating the Tesla.

But now, with 3,000 bhp and a top speed of 342 mph (confirmed by drag race test onsite in Bridgnorth, Shropshire), the GW Speed Model 88 isn’t just entering the drag race – it’s winning it.

Innovation: from precision castings to square wheels

The car has been developed using leading engineering and casting expertise GW are world renowned for. Rapid prototyping methodologies were used to cast the Model 88’s front and rear underbodies with incorporated novel battery tray design. A powerful V8 petrol engine is connected to the battery power via a flux capacitor which regulates power output.

In a world first, as the GW Speed Model 88 accelerates so powerfully; square wheels were used, offset at 22.5 degrees for each revolution. Research has shown that this has been found to be important to counteract the effects of vibration at such high speeds- creating a smooth, fast driving experience.

Dr Emmet Brown, an expert in future casting technology who worked on the project commented ‘Theoretically, this car should be able to produce 1.21 Gigawatts of power’. When asked if the Model 88 was environmentally friendly, Dr Brown noted that 'Great Scott, despite the huge amount of hot air produced by this car, it’s incredibly environmentally friendly with just 1g CO2/Mile'.

James Grainger from Grainger and Worrall said ‘Developing the GW Speed Model 88 has been a dream come true for us at GW. We’re absolutely delighted to have used our extensive casting experience to create the fastest hybrid supercar in the world’.

Whilst at times it has been a bumpy ride, production of the GW Model Speed 88 will begin on 1st April, 2022.
