The Mazzanti Evantra is a high-performance limited production sports car made by Italian automobile manufacturer Mazzanti Automobili. The car premiered at the Top Marques Show Monaco in 2013 and has had several subsequent variants produced. The Evantra is produced on commission, in a maximum of five units per year.

The body is structurally a two-seater coupé. The same body is built in two different types of equipment: pro-body, which made entirely of carbon fiber and one-body, which is built from the same material with some parts built from hand-wrought aluminium.

The engine is a naturally aspirated, 7.0-liter aluminum Chevrolet LS7 V8 engine that produces 701 PS at 6600 rpm and a maximum torque of 848 N⋅m at 4500 rpm. But during prototyping and testing, Mazzanti engineers were able to extract a further 50 HP from the engine.

For final production version, the engine produces 751 PS at 7500 rpm, and a maximum torque of 860 N⋅m at 5000 rpm. The engine has a compression ratio of 11: 1 and is equipped with dry-sump lubrication system, titanium valves and connecting rods.

The Evantra V8 is equipped with a 6-speed sequential gearbox and can reach a top speed exceeding 350 km/h with acceleation from 0–100 km/h taking about 3.2 seconds.

The 781 is an evolution of the 771, replacing the 7.0L LS7 with the same engine found in the Pura, a 6.2L LT2. The engine produces 781 PS.

The aerodynamic development was realised with the support of partners with significant background in F1 and Le Mans. The car is equipped with stock high performance tires 255/30 R20 front and 325/25 R20 rear, mounted on specific 20" OZ Racing wheels, and controlled by a Brembo braking system with carbon-ceramic 380 mm discs and 6-piston calipers at the front and 360 mm discs and 4-piston calipers at the rear.

The Evantra Millecavalli was unveiled at the 2013 Top Marques Show in Monaco. 

The 7.0L LS7 found in the 771 has been enlarged to 7.2L, and fitted with a pair of turbochargers, and now produces 1,000 PS, hence the name, with Mille meaning thousand & cavalli meaning horses.

Sending that 1,000 PS and 1200 N⋅m to the rear wheels is a bespoke 6-speed sequential, which gives the car a claimed 0–97 km/h acceleration time of 2.7 second, and an estimated top speed of 402 km/h.

Again, OZ Racing supplies the wheels which are the same size as the 771 wheels, and are shod with Pirelli Trofeo R tyres, 265/35R19 at the front and 335/30R20 at the rear. Stopping power is provided by 390 mm rotors and six-piston calipers at the front, and 360 mm rotors and four-piston calipers at the rear, with carbon-ceramic brakes being standard. Mazzanti claims that this can bring the car from 300 km/h to a stop in 7 seconds.
