Today, Jaguar Land Rover has taken a big step forward by revealing the 2020 Range Rover Sport HST for the United States. What needs to be underlined now is that Jaguar Land Rover brings a newly-developed 3.0-liter inline-six engine that is able to cranks out 395 horsepower and 406 lb-ft of torque. The new six-cylinder gasoline engine is claimed to have received a mild hybrid touch and will be available in several Range Rover lineups throughout 2020 in the United States, including for the new Range Rover Sport HST.

It Gets a New Six-Cylinder Ingenium Petrol Engine

Unlike the previous supercharged 3.0-liter V6 engine, the new 3.0-liter inline-six is a modern gasoline engine that is part of the Jaguar Land Rover (JLR) Ingenium engine family. This means the new 3.0L six-cylinder unit basically shares the same engine architecture platform with the 2.0-liter turbo four-cylinder engine. Also, what is quite impressive is that the all-new 3.0-liter inline-six is now powered by a single twin-scroll turbocharger combined with an electric supercharger featuring a 48-volt electric system. This is exactly the same as JLR has ever offered on their four-cylinder unit.

The 2020 Range Rover Sport HST is offered in several variants with different power outputs. The entry-level P360 model is able to offer 355 horsepower, while the highest HSE P400 variant is able to cranks out 395 horsepower and 405 lb-ft of torque. Jaguar Land Rover has claimed that the 2020 Range Rover Sport HST (the hottest HSE P400 variant) can accelerate from 0-60 mph in just 5.9 seconds, while the sprint from 0-62 mph can be achieved in 6.3 seconds. Of course, it’s 0.9 seconds faster when compared to the Range Rover Sport with a supercharged 3.0-liter V6 engine that produces 380 HP.

Thanks to the use of a single twin-scroll turbocharger and electric supercharger, the new Range Rover Sport HST (HSE P400) has a top speed of up to 130 mph. Basically the new electric supercharger component helps the inline-six 3.0L gasoline engine to provide a better power response. This means that the electric supercharger has eliminated the turbo lag problem because it’s now able to spool completely in just 0.5 seconds.

The electric supercharger is very different from the traditional exhaust-driven turbocharger which often experiences turbo lag problems. However, this concept seems quite familiar and exactly the same as you can find on other vehicles on the market like the Mercedes-AMG CLS53 and E53. Besides giving a boost to its electric supercharger, the 48-volt electric system also helps automatic stop-start system. The new 3.0-liter inline-six engine is also equipped with a variable valve-lift and variable cam-timing, and it’s claimed to be able to improve its fuel economy by 20 percent. Which means it’s far more efficient than the OLD supercharged 3.0-liter V6 engine.

Previously, Jaguar Land Rover had used a supercharged 3.0-liter V6 engine in some of their car lineups for a long time. The supercharged 3.0L V6 unit is basically still a great engine, but it’s compromised. Given that the supercharged 3.0-liter V6 engine actually uses a V8 engine block but with a V6 cylinder head. It automatically makes the weight almost the same as a V8 engine but without providing the same amount of power as the V8 unit. It’s also equipped with a 90-degree cylinder bank angle, since it’s based on the V8 engine block. Of course, it’s not ideal for a supercharged V6 engine, mainly because of engine vibration problems and not so good in terms of its fuel economy.

Release Date and Pricing

JLR hasn’t yet announced its release date, but the 2020 Range Rover Sport HST is expected to reach U.S. showrooms sometime next year. This new mid-size luxury SUV will be available in two new exterior paint colors which include Portofino Blue and Eiger Grey, complete with newly-available 22-inch alloy wheels. These two exterior paint colors basically replace the Loire Blue and Corris Grey that have been offered in the current model. Well, talking about the official price, the entry-level 2020 Range Rover P360 will arrive at U.S. dealerships at a price of $90,900. While the hottest HSE P400 variant is priced at $96,150, followed by the 2020 Range Rover SVAutobiography LWB which will hit the dealer at a price of $209,500. All prices above don’t include taxes and fees of $1,295.
