Don't believe the hype. The engines are rated at 940hp up to 40mph before they then derate back down to 750hp, and acceleration becomes sluggish, frankly. A HST will catch up as its power kicks in higher up the speed range and will cruise past it effortlessly at 125mph like a true thoroughbred, while IEP flaps along struggling to maintain 110mph like a geriatric penguin.

I'll admit the initial acceleration is rocket like, however. End of the day, IEP is what it is due to how DfT specified it, but going by first impressions, Hitachi have made a damn good fist of it.
